Quick Start Guide
The P139 is a complex device with the ability to monitor many sensors associated with distressing conditions that can
occur in bed. It is especially aimed at supporting the care of those with Epilepsy and SUDEP. The alarm can then trigger
an Alert-iT Safelink Pager or Nurse Call/Telecare systems.
This handbook and associated Quickstarts, are intended to assist in adjusting the many alarm parameters to suit the
specific user. The adjustments must therefore be made by someone with skills similar to programming a mobile phone
and who is familiar with the users needs and competent to decide what additional safeguards will be needed, in the light
of the health risks involved. The manufacture offers a free telephone helpline and a range of information sheets to assist
(see page 20).
It is ESSENTIAL to adopt a methodical approach to setting each set of parameters, or the user will soon become
confused as to which sensor is giving alarms or false alarms. Unless otherwise informed the unit will have been shipped
with all alarms other than gross bed movement turned off and the internal audible sounder disabled. This will enable the
user to gradually introduce one sensor at a time and not be confused by false alarms as each setting is tested. Once all
the parameters are proved to be working as required, then the audible alarm can be enabled if required (see Hidden
Menu).
For protection against inappropriate or accidental parameter changes, all settings can be locked in a hidden menu.
Unless there is specific pressing needs, then the following order for setting the sensor parameters is recommended.
After enabling a sensor, then it is recommended that the sensor is used for a few days to establish the optimum setting
that has few false alarms while giving the required security, before proceeding with more sensors.
·Bed Movement
·Shallow Movement (Min=0)
·Bed Occupancy
·Moisture (wetting or vomit)
·Sound
·Shallow Movement (Max-Min) based on learning mode settings
Finally remember there are a set of DEFAULT parameters stored in the unit. If you get into difficulty these can easily be
recalled to establish a known good working state. Once the changes have proven to be successful, then these new
defaults can be saved within the Hidden Menu system.
On page 18 you will find a useful chart that lists all the menu items in order, with space to write the optimum settings
found by the user.
Look out for this “hint” frame
throughout the handbook
Hint for Getting Started
·To start the process, press the top right “Menu” key for 3 seconds to switch the unit on.
·Wait for the “Monitoring” screen. The P139 will return to this screen if no keys are pressed for 30 seconds.The “bar”
display indicates the state of the battery charge. Ensure the charger is plugged in if only one bar is displayed, as the
next stage will be that the unit will automatically power down.
·Press the MENU key again, and all the available settings will be displayed in rotation, starting with the Power Off
capability.
·In general the RIGHT arrow key will turn-on and increase the displayed parameter, while the LEFT key will
decrease and eventually turn off the parameter.
·The UP key will scroll back through the menu system, stopping at the “Monitoring Screen”. It also acts to RESET
any alarms that are active.
Refer to the main book section for hints on how best to begin setting each parameter., which will appear in a frame like

P139 GUARDIAN MONITOR INSTRUCTIONS
IMPORTANT
Please read these instructions carefully before using the equipment and keep readily available for reference
purposes.
It is not intended for this equipment to be used in diagnosis of medical conditions or for the measurement of any
physiological processes. If the user is considered to be at high risk it should not be used without medical advice and
support.
The equipment can, when used correctly and in accordance with the instructions, be used to give warnings of
symptoms that may be related to particular conditions. The equipment, for a number of reasons, cannot be guaranteed
detect the symptoms being monitored and is not a substitute for direct supervision.
If there is ever any cause for concern with the performance of the equipment the supplier should be contacted.
DISPLAY & CONTROLS
Overview
A liquid crystal display screen with back lighting and a touch sensitive keypad is provided in order to indicate and
adjust, as required, the functions and the status of the system.
In the event of an alarm condition a highly visible red alarm light will flash on the top of the monitor (through this can
be disabled if it cause a nuisance) There are a number of screen displays, which provide details of each function and
allow adjustment of the various settings. Pressing the 'menu' button advances the screen display in sequence and the
settings can be adjusted by pressing the ‘INCREASE’ or ‘DECREASE’ buttons. By pressing the 'menu' button
repeatedly, the screen displays can be scrolled in sequence until the one required is observed. BACK reverses the
menu scrolling, stopping at the “Monitoring” screen, it also functions as the ‘ALARM RESET’ button when an alarm
condition is active.
The 'menu' button has the additional functions of a ‘POWER ON’ switch when the monitor is turned off
Continuously pressing a button has the same effect as repeated pressing.
If no buttons are pressed for longer than 30 seconds and no alarms have been activated the backlight turns off and
the screen will show the normal “monitoring” display.
When sound or motion is detected this is indicated by display symbols on the screen situated above the sound and
motion arrows. This facilitates testing and validating the monitor.

POWER Control
The monitor has an internal battery designed to maintain full operation during mains failure. It is charged by a mains
adapter which should be mounted in a well ventilated area. To isolate the monitor remove the charger connection.
Press and hold the ‘POWER ON’ button for 3 seconds to switch on the monitor. A start-up display will indicate the model
number and software issue, as well as the monitor identification and site identification numbers for the radio version.
After approximately 5 seconds the normal monitoring display will be observed on the screen.
If an alarm is activated, the screen will indicate the relevant alarm message and override the monitoring display.
To turn off the monitor press the 'menu' button until the “Power screen” is visible (one press from the normal monitor
screen). Press the DECREASE < button once turn-off the unit (note this functions can be disabled in the HIDDEN
menu). Power Off results in the Alarm OFF message (Fault 29) being sent as a warning that the monitor is off. If this is
an acceptable condition then the pager indication can be removed with the RESET ALL function, by disabling FAULT
warnings in the pager FUNCTION menu. After this RF Fail messages can be expected on the pager as the unit is no
longer transmitting its heartbeat signal (which can be silent) or the monitor can be temporarily deactivated in the pager
MONITOR SCREEN
Alarm monitoring is ONLY active when this screen is displayed. If no key is pressed for 30 seconds in any of the other
“menu” screens, then the monitor will revert to this screen and alarm monitoring will commence.
The backlight automatically extinguishes after 30 seconds so not to disturb users at night. Pressing the BACK button
will re-illuminate the screen without affecting the monitoring readings
LINE1: MONITOR ACTIVITY
With no alarms active the screen will show:
ALARMS OFF! This warns that no sensors have actually been enabled
ACTIVE: The normal state when the monitor is sensing for a condition
=zZ following ACTIVE shows the Snooze feature is enabled and can be activated
SUSPENDED: Followed by s (shallow movement & sound), m(moisture), b (bed vacation) shows which sensors are
temporarily suspended , until normal activity is again detected.
LINE2: STATUS INFORMATION
There are three different modes of presentation on this line:
In the basic monitoring condition the shallow movement rate will be displayed in movements per minute
Or If the Max/Min Shallow Movement Recorder is enabled (in HIDDEN menu) this will show instead.
Following this, if a Bed Occupancy Sensor is fitted, the word VACANT or In Bed will appear when appropriate.
However:
If SNOOZE is active then the time countdown will be displayed instead of all the above
ALARM ACTIVATING & RESET
When an alarm is activated the cause appears on line 1 of the screen with a minute/seconds counter on line 2 showing
how long the alarm has been active. Any active alarm condition can be reset immediately by pressing the ‘ALARM
RESET’ button so that the message “ALARM RESET” is displayed. After a period of 3 seconds the display screen will
return to the Monitoring Screen, providing that no further alarm conditions are activated.
Many of the alarms can be individually configured to be latching or automatically resetting. When an alarm is configured
as latching, then once activated the alarm will continue until it is manually reset by pressing the ‘ALARM RESET’ button.
When an alarm is configured as auto resetting, the alarm will automatically cancel as soon as the conditions causing
the alarm have reverted to normal., though the screen will continue to show that the alarm was activated for 60 seconds.
The configuration of the alarms as latching or auto resetting is made with the Hidden Settings screens. It is our practice
to set all the alarms as LATCHING on radio versions to ensure the carer has to attend to the user and there is no
uncertainty as to the cause of the alarm. For the wired versions, which are usually connected to Nurse Call or Telecare,
we set all the alarms as non-latching so that the carer only has one RESET point, that being the Nurse Call point.
SNOOZE
There may be short times when it is desirable to have the Bed Movement alarms temporarily disabled. This is particu-
larly useful if the user is restless for a period after going to bed, there is a need to use the bed for a caring activity or
the user wants some privacy for a while. From the Monitoring screen pressing the RIGHT INCREASE button (as indi-
cated by >=Zz) will show a time increasing in 5 minute steps. This will count down to zero, at which point the alarm
monitor will recommence. Pressing the DECREASE button at any time will cancel the snooze period.

P139 GUARDIAN MONITOR INSTRUCTIONS
Radio Transmitter option (P139Bxx)
Model P139B includes a transmitter module, which will pass an alarm condition to a remote P137 or P168 Pager. Any
alarm indication that causes the red light on the P139 to flash will also cause an Alarm to be indicated on the Pager.
Resetting the alarm at the P139 will also reset the Pager.
The radio transmission is “failsafe” in that if a regular heartbeat signal is not received, then the Pager will indicate that
the RF link has failed (and hence the user may be at risk). This should be remedied immediately. Please see the Pager
handbook for fault finding suggestions.
The communication address for this option is the ID Number displayed on the front panel, which can be adjusted from
1-64 within the hidden menu.
Alarm Receiver Option (P139xxB)
Models without a radio transmitter can house a P155 radio receiver unit that can be triggered by any compatible Alert-iT
Care Alarm. In particular this has application for monitoring day-time falling, where the client wears a radio linked Fall
detection badge (eg P135). Should the detector be activated then a radio communicated alarm will trigger the P139 to
display “External Alarm”, and pass the alarm to any connected equipment (eg Nurse Call). For details how to pair the
receiver with alarm units please see the P155 handbook (UH1093). The EXTERNAL ALARM is always non-latching by
default, as it assumes the external equipment will control the reset condition.
MONITOR FUNCTIONS AND DETECTION OF SYMPTOMS AND CONDITIONS
SHALLOW BODY MOVEMENTS
This function can be used when the movement Sensor Plate is plugged into the yellow socket marked
“movement sensor” on the rear of the monitor.
The Sensor Plate can detect normal slow body movements which are associated with general muscle, diaphragm,
stomach or heart activity. While the monitor ignores most low-level vibrations, care must be taken to ensure that the cot
/ bed being monitored is not subjected to continuous vibration, as this could delay or prevent activation of the alarm.
This point can usually be covered via the Confidence Check procedure described later.
A “learn mode” is used to establish the normal shallow movement activity from which a Max and Min alarm condition
can be set, which may help to warn of the onset of a TONIC condition. It is also possible to send an alarm if all movement
ceases for a set period, as may indicate a SUDEP condition
Bed Movement Sensor Installation
The Sensor Plate with the label side uppermost should be placed on a firm, flat surface
UNDERNEATH the mattress so that it will be located centrally under the area of the abdomen
of the user. If the surface below the mattress is not firm or flat, the Sensor Plate should be
supported by placing it on a piece of non-resilient board. Ideally the board should be made to
cover the area under mattress and be made of a material such as plywood of at least 2 mm
(1/8”) thickness. The cable from the Sensor Plate should be located so that it will not be liable
to damage or present a hazard to the user. Ensure that thick bedclothes are not tucked
under the edges of the mattress which might lift the underside of the mattress away from the
Sensor Plate.
!
The detection of TONIC seizures or SUDEP cannot be guaranteed with precision. The monitoring of
shallow bed movements is a powerful tool in supporting users vulnerable to these conditions but
may need to be supplemented depending on the health risks involved. The carer must make this risk
assessment and the manufacture should be contacted for further advice as necessary
P140 Bed Movement Sensor
Mount with side shown upper-
most for best sensitivity
ŸThe Sensor Plate should not be used in a moving pram, vehicle or in a rocking cot/crib.
Draughts blowing over the bed/cot/crib may be detected by the Sensor Plate as shallow move-
ments. This would delay or prevent activation of the alarm. The use of fans directed towards the
bed/cot/crib should be avoided.
ŸThe movement alarm will not necessarily detect early stages of choking as the rapid body move-
ment and strengthened heart rate may be interpreted as acceptable shallow movements
The use of this monitor alone for detecting SUDEP is not recommended
!

P139 GUARDIAN MONITOR INSTRUCTIONS
UH1075_P139_Instructions_English.ppp 29/08/2016 16:01:45 Page 5 of 22
SHALLOW MOVEMENT MINIMUM
If the movement rate falls below this setting the monitor display will show the alarm message “SHALLOW MIN”.and
the alarm output will be activated. The setting ranges from OFF to 10 mpm (movements per minute)
The movement rate is usually averaged over a minute, but as an additional precaution zero movement detection is
ONLY delayed by the Shallow Movement Delay, which should be set to avoid false alarms during apnoea type events
(30 seconds is recommended)
See SHALLOW MOVEMENT ADJUSTMENT below on how to set the optimum value.
SHALLOW MOVEMENT DELAY
This sets the time after which an alarm (SHALLOW MOVEMENT) is raised when all shallow movement ceases. The
value is set to avoid false alarms if the user exhibits periods on excessive stillness normally (eg in sleep apnoea), but
fast enough to protect the user should a serious life threatening condition occur. If the user is know to be susceptible
to this condition then the carer is responsible for assessing the risks of using this monitor and determining any
additional surveillance necessary
SHALLOW MOVEMENT MAXIMUM ALARM
If the movement rate rises above this setting, the monitor will show the message “SHALLOW MAX”, and the alarm
output will be activated. The setting ranges from OFF to between 20 and 30 mpm.. WARNING: Very fast panting (faster
than 2 seconds) will be ignored as this conflicts with heart beats under stress and may therefore compromise fast
detection of SUDEP. However continuous activity at this rate will result in Shallow Movement Alarm instead due to the
lack of signal.
See SHALLOW MOVEMENT ADJUSTMENT below on how to set the optimum value.
SHALLOW MOVEMENT ADJUSTMENT
The normal sleeping pattern of a user will lead to great variability in the normal shallow movement pattern. The
Guardian Monitor has a built-in MAX/min movement recorder to help assess the optimum settings.
ŸIn the HIDDEN MENU (see later) the MAX/min DISPLAY function is enabled.
ŸThe Monitoring screen (when no alarm is active) will then display the Maximum and Minimum recorded values
at the start of the second line.
ŸThe carer resets these to a nominal value of 15 at the start of the recording period by pressing the DECREASE
(<) button.
ŸAt the end of the recording period the values are noted and used to judge the best limits for the SHALLOW
alarms.
Hints on setting Shallow Movement Monitoring
1. Using the TICK function is very useful to hear the movement sensor working.
2. Set the Shallow Magnification at 4 and with no user in the bed and no one touching the bed,
check the small x symbol does NOT appear on the screen. Decrease the magnification if
necessary to stop any sensor activity.
3. With the user or someone of similar weight lying on the bed check that the small x symbol
appears regularly on the screen (particularly with each breath). Increase the Magnification if not,
then recheck the x stops with no-one in the bed.
4. If SUDEP is of concern then set the Shallow Delay to 30 seconds and Shallow Min to 0. In this
case also perform a risk assessment to ensure an appropriate range of monitoring is used
5. On the first few nights do not use the Shallow Alarm Max/Min alarms but enable the “MAX/min
Display” recorder function in the hidden menu to detect the suitable settings
6. Once the user is sleeping press the DECREASE button (<) to reset & start the recorder
7. In the morning and before the user is awake, note the Max/Min readings and use these to set the
alarm values with a margin to prevent false alarms.
8. Validate operation during observed seizures and adjust the magnification and detection limits as
required. The manufacturer can be contacted for advice as required

UH1075_P139_Instructions_English.ppp 29/08/2016 16:01:45 Page 6 of 22
P139 GUARDIAN MONITOR INSTRUCTIONS
RESET and SUSPEND SHALLOW MOVEMENT MONITORING
If the alarm is active and latched (eg on radio units), then press RESET to clear the alarm. The monitoring will then
be suspended until 10 movements are detected (indicating the user safely in bed) or the Bed Occupancy signal is
present. This allows the monitor to remain dormant in the day, and automatically revert to monitoring at night or
whenever the bed is occupied.
For non-latched (eg Nurse Call) units, the alarm will automatically clear once movement is again detected. Alterna-
tively press RESET to suspend the monitoring.
Using the Bed Vacant signal provides a secure automatic way to prevent false alarms when no-one is in the bed,
though a risk assessment is essential as it will inhibit alarms if the person falls out of bed or moves off the occupancy
sensor mat (eg in a double bed).
The monitor must be checked that it has returned to ACTIVE once the occupant has settled back in bed
Using the suspend function is preferable to turning the unit off as there is no chance of the user returning to bed un-
protected (bar equipment failure).
SHALLOW MOVEMENT MAGNIFICATION
To allow for different thickness, structure and composition of mattresses and the depth and degree of the
user's movements, the monitor has an adjustable threshold setting.
ŸTo help set this an audible “tick” can be enabled to sound each time a shallow movement is detected. Hence
set TICK VOLUME to 8 (full volume) and have the user or a suitable subject lie as still as possible on the bed.
ŸAny Bed Occupancy Sensor should be disconnected for this test.
ŸThe SHALLOW MAGNIFY is then increased until a regular series of ticks is heard, at least as often as any
chest motion is observed.
ŸThe bed should then be vacated and the ticking should cease, to check that room vibrations or air currents do
not cause unwanted activation of the movement detection function. Should this occur then the MAGNIFICA-
TION must be reduced and the above tests repeated.
ŸAfter successful setting, turn off the TICK facility.
ROUTINE TESTING SHALLOW MOVEMENT DETECTION
The Monitor should be tested on a regular basis. The confidence check establishes that the shallow movement alarm
is operating correctly. For test purposes the bed should be empty. Push the mattress gently and rythmically and note
that a * symbol appears in the bottom right of the display. Check this does not appear when there is no movement
applied.
BODY SPASM MOVEMENT MONITORING
The spasm movement monitoring function of the monitor uses the bed movement sensor. For details see Bed
Movement Sensor Installation (Page4)
When the Monitor has detected a spasm movement of sufficient intensity, a ‘#’ symbol will flash on the screen above
the motion arrow in time with each movement.
SPASM ALARM
The seizure alarm is activated when movements are detected which are greater than a pre-set energy level and faster
than a pre-set frequency, as well as lasting for at least a pre-set period. The monitor will then display the message
“SPASM MOVEMENT ALARM”, and the alarm output activated.
SPASM DELAY
This setting adjusts the minimum period that movements need to persist before the alarm is activated. The period is
adjustable between 5 and 60 seconds or, alternatively, the spasm alarm feature can be switched off. This can be done
by pressing the 'menu' button until the screen “SPASM DELAY” is observed. Press the ‘INCREASE’ button to turn the
seizure alarm function on and increase the setting. Press the ‘DECREASE’ button to decrease the time setting.
Decreasing the time below 5 seconds will turn off the seizure alarm function.
If the time delay is set for too short a period, this will give an early warning of body movements, which may not
necessarily be seizure movements, and is more likely to cause false alarms. If the time delay setting is increased this
should reduce the probability of false alarms, but may not detect spasm movements of short duration. Some prior
knowledge of the nature of the user’s seizure patterns is desirable to make a suitable choice of the time delay setting.
The monitor will normally be provided with a pre-set time delay of about 15 seconds for general use and may not need
to be changed, unless a more suitable specific setting can be selected based on experience with the user.

P139 GUARDIAN MONITOR INSTRUCTIONS
UH1075_P139_Instructions_English.ppp 29/08/2016 16:01:45 Page 7 of 22
To adjust the setting, press the 'menu' button until the “SPASM MAGNIFY” display is observed. Press the ‘DECREASE’
button for higher energy movements and to decrease the detection gain Press the ‘INCREASE’ button to increase the
gain for detection of low energy movements.
SPASM RATE SETTING
This adjustment can assist in distinguishing between the movements associated with normal body activity and rhythmic
spasms. The spasm rate setting can be adjusted between 1 and 4 seconds between each spasm. This adjustment is
intended to prevent the alarm from being activated by slow, repetitive movements, which are not typical of a seizure.
To adjust the spasm rate setting, press the 'menu' button until the “SPASM RATE” display is observed. Press the
‘INCREASE’ button to increase the frequency limit (so that more rapid spasm movements are required to activate an
alarm condition). To reduce the rate limit press the ‘DECREASE’ button (This will allow detection of seizures with both
rapid and slow movements).
Setting the spasm rate limit to a low value may cause alarm activation with other normal movements and cause false
alarms. By setting the spasm rate limit too high the probability of false alarms will be reduced but a seizure may possibly
remain undetected. If in doubt initially set the rate limit to a high value and gradually decrease this, as necessary, in
order to eliminate false alarms
RESET SPASM MOVEMENT MONITORING
If the alarm is active and latched (eg on radio units), then press RESET to clear the alarm.
For non-latched (eg Nurse Call) units, the alarm will automatically clear once gross movement ceases.
The Spasm Monitor cannot be suspended as it will not false alarm when no-one is in the bed
SPASM MAGNIFICATION SETTING
The body movement energy level which can be detected is adjustable in 8 steps. Setting the spasm magnification at a
high level will allow minor movements to be detected, at a low level the movements would need to be more energetic in
order to be detected.
Routine Testing of Spasm Monitoring
Check the operation of the spasm alarm by repeatedly pressing on the mattress to simulate body spasm movements,
and observe the # symbol appears with each press..
TRANSIENT SOUND ALARM
This alarm is designed to respond only to transient or non-continuous sounds in order to eliminate detection of
background noises such as from radio, TV or talking. The monitor uses a microphone located in the top of the enclosure
to detect sounds. The monitor will respond best when situated close to the source of sound but the exact positioning is
not critical because the microphone is equally sensitive in all directions. An optional external microphone can be used
(P158) id difficult situations to better target the sound source.
When the monitor has detected a sound, an bracket symbol (will flash in time with each sound on the display
screen above the sound arrow indicator.
Hints on setting SPASM detection
1. Turn off all other alarm sensors and use only the Spasm Detection.
2. Use the following settings as a start.
Spasm Delay 15 seconds
Spasm Rate 3 seconds between spams (or faster)
3. You will note this means the system will require a minimum of 5 spasms to trigger the alarm, which
is acceptable.
4. Set the Spasm Magnification at mid point (4), and test the # appears when the bed is pressed, but
with less movement than the seizure produces. If not, then check the connection and position of the
sensor plate. Then increase the Magnification until reliable detection occurs. This test SHOULD be
conducted every evening
5. Ensure the # symbol does NOT appear regularly on the screen while the user is lying still or asleep
normally. If it does then the magnification will need to be reduced.
7. If the system is failing to detect, then please note if the # symbol is flashing on the display while the
seizure is in progress. If not, then the Magnification must be too low or the pad position is poor.

P139 GUARDIAN MONITOR INSTRUCTIONS
The transient sound alarm is activated when a sequence of transient sounds above a pre-set sound level occur within
a pre-set time period. The sequence must repeat faster than a present frequency. The transient sound alarm can be
set to respond for example to a baby crying, as well as personal vocalisations during a seizure or to someone calling
for help. It is particularly designed to mirror the detection pattern used for Seizure Monitoring.
When the monitor detects sounds, which meet the set criteria, the monitor will display the message “TRANSIENT
SOUND ALARM”, and the alarm output will be activated
SOUND DELAY TIME
The transient sound alarm requires the sounds to continue for a set time period. The time period commences with the
first sound and continues for the pre-set time. This period can be set between 5 and 60 seconds in 5-second steps.
To adjust the sound monitoring period or turn the sound alarm function on or off, press the 'menu' button until the
“SOUND DELAY” display is observed. Press the ‘INCREASE’ button to turn the sound alarm function on and increase
the setting. Press the ‘DECREASE’ button to decrease the time setting. Decreasing the time below 5 seconds will
turn off the sound alarm function.
SOUND MAGNIFICATION
The sensitivity to sound can be adjusted with this setting. This can be set in 8 steps .
To adjust this setting press the 'menu' button until the “SOUND MAGNIFY” display is observed. Press the ‘DE-
CREASE’ button to decrease the gain (for louder sound) or press the ‘INCREASE’ button to increase the gain (to
detect quieter sounds).
SOUND RATE
To activate the alarm, the sound bursts must occur faster than the rate set.
To adjust the rate, press the 'menu' button until the “SOUND RATE” display is observed. Press the ‘INCREASE’ button
to increase the rate or press the ‘DECREASE’ button to decrease the rate.
RESET SOUND MONITORING
If the alarm is active and latched (eg on radio units), then press RESET to clear the alarm.
For non-latched (eg Nurse Call) units, the alarm will automatically clear once the sound ceases.
The allow for daytime suspending of the alarm, the SOUND monitoring is only active when Bed Occupancy is assured,
by either the Shallow Movement monitor being active (indicating by movement that there is someone in the bed to
monitor) or the Bed Occupancy sensor has been activated
Routine Testing of Sound Monitoring
Tap the unit or click fingers to stimulate a sharp sound and note the ) symbol appears
MOISTURE ALARM (A Patient Connected Sensor)
This is used to detect excessive perspiration or bed wetting with urine or, with a sensor sheet over the pillow, saliva
or vomit, All can be a consequence of an epileptic seizure.
Hints on setting SOUND detection
1. With the user is sleeping normally in the bed, set the sound magnification to maximum and observe
the occurrence of the “(” symbol on the display. It is reasonable that this may appear occasionally due to
some outside noise, but if it appears regularly (so that it would trigger an alarm) then decrease the magnifi-
cation until it stops).
2. Set the alarm conditions to
Sound Delay 10 seconds
Sound Rate 3 seconds between sound bursts or faster
3. If the system fails to detect seizure please observe if the “(” symbol is being displayed with the
sounds made by the user during a seizure, and raise the magnification if not.
4. If the system is prone to false alarms then try decreasing the magnification. If this leads to failure to
detect then reset the magnification and increase the Sound Rate. Finally you may try increasing the time
delay to 15 seconds .

This function of the system can be used when the lead of the moisture detection sheet is plugged into the blue socket
marked “Moisture” at the rear of the monitor. The monitor has special isolation circuitry built in to ensure safety of the
user in all foreseeable circumstances. The standard provision is a two connector lead, with the leads connecting two
adjacent outside studs (ie NOT the two inside studs). There is an optional 4 press-studs cable which not only allows
moisture detection but also warns of a sensor failure. However this gives permanent FAULT alarms while the sheet is
removed for laundering.
The alarm is activated when the sensor sheet becomes moistened with fluid of sufficient electrical conductivity. The
message “MOISTURE ALARM” will be displayed and the alarm output activated
The alarm will only cancel if the moisture detection sheet dries, is removed or is replaced with a clean dry one.
Moisture sensor fault detection
For the normal 2 connector cable the sheet is tested after fitting by connecting the two spare studs together with a
metal object (e.g. spoon or key). This should cause a Moisture Alarm condition.
If the 4 connector cable is used then automatic fault detecting can be set in the Hidden Menu. If the moisture detec-
tion function is active and the sensor is not connected to the monitor or a wire broken in the sheet, then the message
“MOISTURE SENSOR FAULT” will be displayed, and an alarm output is activated. The alarm is reset when the
sheet is correctly connected, but can be suspended by pressing RESET (and SUSPENDED m will be displayed).
The normal monitoring will resume as soon as a functional sensor sheet is connected to all 4 connectors.
MOISTURE CONDUCTIVITY SETTING
The sensitivity to the conductivity of the liquid required to trigger the alarm can be adjusted in 5 steps from that for
moist to wet. Using the least conductive setting will cause the monitor to produce alarms with most liquids, inclusing
perspiration. Setting the conductivity higher will make the monitor more selective, and will only produce alarms with
more liquid.
To adjust the conductivity setting, press the 'menu' button until the ‘MOISTURE’ display is observed. Press the
‘INCREASE’ button to turn the body moisture alarm function on and increase the setting. Press the ‘DECREASE’
button to decrease the conductivity setting. Continuing to decrease the setting will turn off the moisture alarm function.
BED OCCUPANCY
This function can be used to provide a remote alarm after a preset period when the bed is vacated. It can be set to
allow the user to leave the bed for a given time but generate an alarm if they have not returned within a preset time
limit. The time period between the bed being vacated and the bed occupancy alarm activating can be set between 5
seconds and 24 hours. This feature will also stop nuisance alarms from the Shallow Movement and Sound sensors,
whilst the bed is vacant. However to ensure failure of the mat does not permanently inhibit these alarms, a bed
vacation alarm will always happen at least after 24 hours (the maximum time delay possible). Shorter times MUST be
used if the user could fall from bed or move off the mat and thus inhibit the shallow movement or sound detection.
This function is enabled in the Hidden Menu and allows for two possible sensor types, Bed Sensor or Dynamic
Sensor Connection
There are currently 4 types of device that can be used.
1.Bed Leg sensor platform for location under a bed leg
This adjustable device detects the change in weight of a bed when it is vacated. It acts as a normally closed
switch when adjusted for an occupied bed.
2. P143C Pressure sensitive mat for use in the bed under the user
In general the mat must be installed on top of the mattress, which should be firm. The mat is waterproof and
easily wiped clean in the event of soiling. The mat will act as a normally closed switch for an occupied bed.
Hints on setting Wetting detection (either Bed or Pillow
1. Install the sensor pad in the bed on top of any waterproof mattress or pillow protection but
under and comfort sheet and connect.
2. Enable the alarm with the lowest sensitivity. Please note that if the sensor pad is
automatically tested for damage and a “Sensor Failure” will show if a wire is broken or the plug not
inserted correctly.
3. If the system fails to detect, then note if the pad has been penetrated by moisture and
reposition if necessary.
4. If the system to too sensitive (eg to dribbling or just slight wetting), then set the sensitivity
accordingly.

P139 GUARDIAN MONITOR INSTRUCTIONS
Operation of Alarm
When the bed is vacated, thereby releasing the pressure, the shallow movement sensing is frozen to prevent any
alarm from being activated. This enables a user to leave the bed temporarily without setting off alarms unnecessar-
ily. The vacation is indicated on the normal display screen with the word “Vacant”.
When the bed is re-occupied and the pressure sensitive switch is activated the shallow movement function will
resume after a short time. The occupation is indicated on the normal display screen with the word “In Bed”.
If a time has been set for the bed occupancy alarm feature an alarm will be generated after the set time period, the
monitor will display the message “BED OCCUPANCY ALARM”,and the alarm output will be activated.
Bed Occupancy Alarm Setting
To adjust the bed occupancy alarm delay setting, press the 'menu' button until the “BED OCCUPANCY” display is
observed. Press the ‘INCREASE’ button to increase the delay period. Press the ‘DECREASE’ button to decrease
the delay period,or turn the sensor OFF
Reset and Suspending the Bed Vacation Monitoring
If the alarm is active and latched (eg on radio units), then press RESET to clear the alarm. The monitor will then be
suspended (showing SUSPENDED b), until the bed is re-occupied.
For non-latched (eg Nurse Call) units, the alarm will automatically clear once the bed is re-occupied., or it can be
suspended by pressing RESET.
External Alarm
This alarm is only available on the P139xxC with the internal alarm receiver unit. This module can be coupled with
up to 32 radio linked alarm monitors and if any trigger an alarm there will be:
ŸA period of 20 seconds while an audible tune is played, allowing the user to reset the source off any false
alarm
ŸActivation of the alarm, with the message EXTERNAL ALARM displayed.
ŸThe alarm is usually reset by resetting the external equipment.
Auto-testing of Sensors
The Guardian MK3 introduces a major capability towards total reliability in monitoring. All the sensor signals are
continuously monitored for activity, even if not an a level to stimulate an alarm. If there is no sign of activity in a 24
hour period then a fault alarm is raised as this could mean the senor or connecting cable has failed. The ONLY
way to clear this alarm is to stimulate the sensor in the manner shown in the Client Set-Up Table on page 18
Remote Reset
This feature is available for the Radio (P139B) versions only and is enabled in the Hidden Menu. In essence this
stops the Guardian sending Alarm Clear messages to the pager. Instead a separate radio button mounted near to
the Guardian sends the clear signal when pressed. This allows the Guardian, with all alarms in “auto-reset” mode,
to be discretely mounted under the bed so as to not draw the attention of the client who might damage such
equipment. The pager will indicate an alarm condition but can only be reset if the alarm condition has ceased
such that the Guardian has self-reset and a member of the care staff has attended the room and pressed the re-
mote reset button. Ask Alert-iT for information about hiding the monitor inside the matress.
Recall Default
In the “hidden menu” the supervisor can store a complete snapshot of all the settings as “default”. Hence should
the operator accidentally adjust any setting wrongly, this function will restore this saved default.
Hints on use of Bed Occupancy Sensor
1 If the user is known to leave the bed at night, or if the shallow movement false alarms indicate this is
happening, then install the bed occupancy sensor. With the bed vacant the display should shows the word
VACANT. Check that this word is not present when the user is in bed and sleeping normally.
2 If the user is known to risk collapsing out of bed then there is the ability to raise the alarm on
extended vacation.

Maintenance
Alarm Output Socket
The multifunction alarm output socket is usually used to activate Nurse Call
or Telecare devices. It also has power available for activating other equip-
ment :
● Pin 3: Normally open contact output (closes for 2-3 seconds on
alarm if non-latching mode set)
ŸPin 1: Normally closed contact output. (opens 2-3 seconds on alarm if non-latching mode set)
ŸPin 2: 12 volt power output (50 mA max.) To special order
ŸPin 5: Power zero volt/chassis connection
BATTERY
An internal rechargeable battery allows the monitor to continue uninterrupted operation in the event of a mains power
failure for several days or it allows the monitor to be used for short periods without a mains supply.
Battery Level Indication
When the battery status bar indication is static with hollow boxes, then the battery is powering the unit and there is no
charger attached (and functioning). The number of bars approximately indicates the battery charge condition as follows:
4 bars: 75 to 100% level (Fully charged)
3 bars: 50 to 75% level
2 bars: 25 to 50% level
1 bar: Up to 25% level (battery needs recharging immediately)
The later situation will be accompanied by short clicks from the audible alarm to ensure the potential danger is recognised.
Battery Charging
If possible, the monitor should be connected to the AC adaptor at all times. Prolonged periods of disconnection should
be avoided. An inbuilt charger continuously monitors the battery condition. The battery charger has a number of modes
of operation to maintain the battery in optimum condition.
Trickle Charge: While the monitor is connected to the mains supply via the AC adaptor the battery is trickle charged
to maintain the battery voltage, even when the monitor itself is switched off. In this situation the Battery Status bargraph
are solid black and static.
Fast Charge: If the battery needs charging, for example after a power cut, it will be automatically charged rapidly. This
process is indicated by the battery bar graph continuously cycling from 1 through to 4 bars.
Top up charge: When the battery is nearly fully charged or when the battery needs charging during normal
usage, intermittent charging will occur. This is indicated by intermittent cycling of the indicator from 1, 2, or 3 through
to 4 bars.
Notes: Fast and Top up charging will only occur while the monitor is switched on with the mains adaptor operative.
Battery Fault: If the battery cannot be charged to its full capacity, the bars on the indicator are replaced with question
marks ‘????’. The charging process will continue in an attempt to reinstate the battery condition and, if successful, the
display will revert to normal. If the Battery fault indication continues for more than a few days, the battery should be
replaced with an identical type available from your supplier.
Battery care
The type of battery used is capable of being continuously kept on charge and topped up to full capacity.
End of Battery life
The battery will need to be replaced when the battery fault indication persists for several days. This requires advanced
maintenance and a special battery pack after opening the case, so please contact the manufacturer.
Battery capacity check
Periodically, after about every 12 months of daily use or after an extended period of non-use, the capacity should be
checked. This is done by first waiting for the battery to reach the fully charged condition (steady 4 bars while the AC
adaptor is connected and switched on), and then disconnecting the AC adaptor and allowing the monitor to operate from
the internal battery alone.

P139 GUARDIAN MONITOR INSTRUCTIONS
If, after 24 hours use, the monitor shows 2 bars, or more, the battery has some useful service life remaining. If the
monitor fails to operate for the full 24-hour period or the battery charge level has dropped to 1 bar the battery should be
replaced.
Periods of non-use
If the monitor is not going to be used for an extended period, ensure that the battery is fully charged before switching
off and storing the monitor. Power is disconnected by removing the mains plug. The monitor can be deactivated
temporarily in the professional pager to stop RF Fail alarms.
Battery Replacement
Battery Type: 7.5v 1500mAh NiMH Bespoke Battery Pack available from iTs Designs Ltd
Note: When the battery is removed and replaced the monitor settings will revert to the default settings that have been
pre-programmed. Thus ensure the defaults are safely saved (see HIDDEN menu) before removing the battery.
To replace or remove the battery, first switch off the monitor and disconnect the AC adaptor as well as any other
connecting leads. Remove the four base screws and open to expose the inner circuit board. Disconnect the battery
leads from the main board. Remove the main pcb after removing the 65 retaining screws. Cut the 2 tie clips holding the
battery and dispose of the old battery safely. Mount the new battery using 2 new tie clips and refit the circuit board with
the 6 retaining screws. Re-connect the 2 battery leads, The base of the monitor can now be refitted .

INSTRUCTIONS FOR HIDDEN SETTINGS
These instructions are normally only used by service personnel or by the technical staff of authorised distributors of this
product and allow functions to be tailored to a particular user's specific needs as follows:
· Locking changes to menu items.
· Enabling or disabling of the internal audible alarm
· Radio Identification number setting.
· Site Identification number setting.
· Setting Alarms as latching or auto resetting.
· Saving of default settings.
To gain access to the hidden settings press the 'menu' button until the ‘POWER’ screen is displayed (one press from
normal MONITOR screen) then press and hold the ‘INCREASE’ button for 10 seconds as shown on the countdown
Hiding or display of menu Items
Once you have gained access to the hidden settings the main menu entries for groups of functions can be set to either
‘ADJUSTABLE’ or ‘LOCKED’. (see table below)
Press the ‘INCREASE’ button to set to ‘ADJUSTABLE’ or press the ‘DECREASE’ button to set to ‘LOCKED’. Press the
'menu' button to advance down the list. If no buttons are pressed for 30 seconds then the monitor will revert to the
normal Monitoring display.
The ‘ADJUSTABLE’ selection allows full access for adjustment of the settings. The ‘LOCKED’ selection maintains the
current settings but prevents user adjustment.
Additional Control Settings
Power Off Func.
In some cases it is prudent to prevent the user turning the unit off. This can be done here
MAX/min Display
When ON this function shows the maximum and minimum shallow movements that have occurred since starting the
recorder. This allows an intelligent assessment of the best settings for the Shallow Maximum and Shallow Minimum
alarms, to protect those vulnerable to partial or tonic seizures. The recorder is reset to start a new session by pressing
the DECREASE < key.
Audible Alarm
The audible alarm within the monitor can be turned on or off. It is usual to turn the ‘local’ alarm sounder off. In the
Hidden Settings menu advance to the ‘AUDIBLE ALARM’ display with the 'menu' button and press the ‘INCREASE’
button to turn the alarm on, or the ‘DECREASE’ button to turn the alarm off.. Note that the sound is not activated for a
Non-Latched Sound Alarm, as the sound prevents the Guardian detecting the reset condition.
Red Alarm Light
If the front red alarm light is likely to disturb the user, then it can be disabled
Monitor Identification number
When the monitor is fitted with a radio transmitter the monitor can be identified with an ‘ID’ number. This number should
be set specifically so that no monitors operating within range of each other have the same number. In an environment
where several monitors are in use, such as an institution, the ID could be set to match room numbers. When used with
portable pager/ receiver alarms, the ID number can be displayed on the pager to identify the monitor from which the
alarm signal has been received. The ID number can be set between 1 and 63.
In the hidden settings menu, advance to the ‘MONITOR ID No.’ display with the 'menu' button and press the
‘INCREASE’ button to increase the ID number or press the ‘DECREASE’ button to decrease the ID number. The ID
number will scroll from 1 to 250 and 250 to 1.
Site Identification number
For asset management the monitors can be programmed with a ‘Site ID’ number. The site ID number can be set
between 0 and 255.

UH1075_P139_Instructions_English.ppp 29/08/2016 16:01:45 Page 14 of 22
P139 GUARDIAN MONITOR INSTRUCTIONS
In the hidden settings menu, advance to the ‘SITE ID NUMBER’ display with the 'menu' button and press the
‘INCREASE’ button to increase the ID number or press the ‘DECREASE’ button to decrease the ID number. The ID
number will scroll from 0 to 255 and 255 to 0.
Alarm Output
The changeover relay is activated on alarm. It can be set to be activated while the alarm persists (as may benefit its
use for a remote buzzer or beacon), or pulse for 2 seconds (usually required for activating a Nurse Call or Telacare
interface). This pulsing repeats every 2 minutes while the alarm condition persists to ensure it cannot be over-ridden.
Setting Alarms as latching or auto resetting
Once you have gained access to the hidden settings the alarms can be set as either ‘LATCHING’ or ‘AUTO RESET’.
Press the ‘INCREASE’ button to set to ‘LATCHING’ or press the ‘DECREASE’ button to set to ‘AUTO RESET’. Press
the 'menu' button to advance down the list. If no buttons are pressed for 30 seconds then the monitor will revert to the
normal display.
When an alarm is set as latching, once activated, the alarm will continue until it is manually reset by pressing the
‘ALARM RESET’ button. This is the default for radio pager based units as it ensures the carer responds at the room.
An alternative radio solution is to use a Remote Rest button (P176AB). In this case the alarms will be AUTO-RESET
and the Remote Reset facility enabled (see below). When an alarm is set as auto reset the alarm will automatically
cancel as soon as the symptoms causing the alarm condition have stopped. This is also the default for Nurse Call
systems as the wall box has to be reset by the carer and the duplicated reset function would cause confusion.
Remote Reset
This mode has application where the client can be destructive to equipment. The alarms should all be Auto Reset so
that the Guardian Monitor can be hidden under the bed. It is also possible to reverse the supplied bracket so that the
front panel is protected. With REMOTE RESET active, the Guardian does not send All-Clear on reset, this function is
left to an optional Remote button. It does however maintain the Safelink integrity using an Alternative Safelink signal
Saving of default settings
The default settings are those that are reloaded if the latest settings have been lost. This will occur, for example, if the
internal battery is removed and replaced. It is advisable to set the default settings once the monitor has been
configured to a particular user's requirements so that, in the event of disruption to the battery power, the settings will
not be lost. The USER is also able to reload these settings if, for instance, the sensor parameters have been adjusted
wrongly
To save the current settings as the default settings (including all of the user-adjustable settings), enter the Hidden
Settings menu and advance to the ‘SAVE SETTINGS AS DEFAULT’ display by using the 'menu' button. Press the
‘INCREASE’ button to store the settings. The monitor will turn off and once the settings have been stored the monitor
will turn back on in the Monitoring mode.
EXIT HIDDEN MENU
Select to exit the hidden menu loop and return to normal monitoring screen.
