Operation
The secure wandering system is a system that allows
any potential escape attempts by confused patients to
be controlled.
Each exit under surveillance is fitted with a standalone
controller which alerts staff when a person wearing a
special wristband tries to go through it. In the event that
therearenosupervisorystaff near the exitthisinformation
can be transmitted to the BUS/SCS nurse call unit using a
door unit Cat. No. 766 06 configured for this function.
This way nurses receive information on the escapee's
identity and on the door used.
The system can operate using two modes:
• Surveillance mode: An alarm is activated when the
wearer of a wristband is close to the exit and this exit
is open.
• Intruder mode: An alarm is activated when an exit
is opened
Switching from one mode to the other is done manually by
entering a special code into the controller keypad.
Thestaff haveachaperone code which allows a wristband
wearer to be let through an exit under surveillance
without triggering an alarm.
Two control outputs allow:
• The exit to be locked once a wristband is detected in the
vicinity (provide an electromagnetic lock*).
• An audible or illuminated warning signal to be triggered
when an escape alarm is activated.

Device presentation and installation
SECURE WANDERING SYSTEM
Normally situated close to the exit, this controller is the
heart of the system.
All auxiliary elements are connected to it.
A 12-button keypad is used to configure and
activate special functions (mode changes, alarm
acknowledgement, etc.).
A buzzer acts as a warning if an escape is detected.
The door controller retrieves the information from antenna
Cat. No.76621andfromdoor contact Cat. No.431 00 and,
depending on its usage mode, either triggers a nurse call
or locks the door.
When the door is locked it can be unlocked using special
codes.
The coded keypad captures the wristband signal when a
predefined door is crossed.
Requires a modular 12 V= power supply
(Cat. No. 4 131 05).
This system is used to signal crossing of a door threshold by a resident fitted with a wristband Cat. No. 766 20.
It works with door unit Cat. No. 766 06 configured for secure wandering and allowing acknowledgement.

Placed as close to the exit as possible, ideally 50 cm from the ground at the side of the door latch, this element detects the
presence of a wristband Cat. No. 766 20 and informs the controller Cat. No. 766 22.
The sensitivity and therefore the detection radius (around 1 to 15 m) can be set easily using a screwdriver.
A green indicator light indicates that the antenna power is on.
A red indicator light flashes when a wristband is in the detection zone (see setting the antenna).
The antenna activity is permanently checked by the controller.

Worn on the wrist or the ankle, this waterproof wristband is fitted with eyelet closures preventing the person under
surveillance from taking it off.
These wristbands are made of anti-allergy plastic that is capable of being in continuous contact with the skin.
The battery has an expected lifetime of more than one year (although replacing the batteries every year is
recommended).
The weatherproof seal (IP 55) allows residents to take baths and showers.
The wristbands can also be cleaned by placing them in an alcohol bath for 5 minutes.
Wristbands must be removed in the following cases:
- If they are faulty or the battery is dead
- When the resident leaves
- When the resident undergoes an MRI (magnetic resonance imaging) exam
To remove the wristband, cut it with a pair of round-end scissors.
When a wristband is immobile it switches to low-consumption mode. This allows the standalone capacity of the battery
to be increased to a maximum 4 years when stored.
Once movement is detected the wristband switches immediately to operational mode.

Chaperone
The controller must be set to chaperone mode in
order to allow a wristband wearer to go through an exit
without setting off the alarm.
This is done by entering a code on the keypad or by
activating the chaperone input (via a pushbutton or
keyswitch, etc.).
Thechaperone contactmustbenormallyopenornormally

Acknowledgement
When an alarm is detected, the alarm output and the
buzzer remain active until they are acknowledged.
The alarm is acknowledged by entering a code on the
keypad or by activating the acknowledgement input.
The acknowledgement is processed with each change of
state for this input.
The acknowledgement contact may therefore be of any
type whatsoever (NO/NC or powered/non-powered).
Mode selection
The changeover from surveillance mode to intruder
mode and back can be controlled by the state of this
input. When the contact is open (or the input is not
supplied with power) the system is in surveillance
mode. When the contact is closed (or the input is
supplied with power) the system is in intruder mode.

System installation (continued)
Chaperone
The controller must be set to chaperone mode for a
set time period (chaperone period) in order to allow a
wristband wearer to go through an exit without setting
off the alarm.
This is done by entering a code on the keypad or by
activating the chaperone input (via a pushbutton or
keyswitch, etc.).
Thechaperonecontactmust benormallyopenor normally
non-powered.
For optimum security the controller returns to surveillance
mode once the door is opened and closed. The chaperone
period is cancelled.
Acknowledgement
When an alarm is detected the alarm output and the
buzzer remain active until they are acknowledged.
Acknowledgement is via the door unit Cat No. 766 06
by pressing the nurse presence button.
Mode selection
The changeover from surveillance mode to intruder
mode and back can be controlled by the state of this
input. When the contact is open (or the input is not
supplied with power) the system is in surveillance
mode. When the contact is closed (or the input is
supplied with power) the system is in intruder mode.
The system state can therefore be controlled by an
external device (clock etc.).
When this input is not being used, the changeover from
one mode to the other is achieved by entering a code on
the keypad.
OPERATING MODES

15
For the initial commissioning or following a software update or restoration of the default settings (code 9090) the
controller is started up with the standard operating settings which have the following values:
• Controller address: 1
• Chaperone period: 15 seconds
• Door contact operation: Normally Closed (value 0)
• Door contact time delay: 5 seconds
• Chaperone code: 217
• Acknowledgement code: 369
• Buzzer volume: 2
• Mode selection (surveillance/intruder) via wire input (value 0)
• Locking control: Lock (value 0)
• Direction detection: Deactivated
• Surveillance of the radio elements: Activated (value 0)
• User language: French
• System link protocol: 2G anti-wandering system
• No code ltering (surveillance for all wristbands)
Commissioning
FACTORY SETTINGS

16
The parameters can easily be set for the system using simple codes that provide access to the different
parameter setting steps.
A parameter setting is changed by entering the following on the controller keypad:
• 1 - The setting code (90XX codes)
• 2 - E (conrmation)
• 3 - The setting value
• 4 - E (conrmation)
• C: for cancelling an entry being made.
An entry in parameter setting mode is confirmed by an audible signal from the controller lasting 2 seconds.
The system remains in parameter setting mode for 2 minutes and then returns automatically to normal mode.
Entering a valid configuration code extends this period by 2 minutes.
The system remains completely functional in parameter setting mode.
Code: Parameter
9001 Chaperone period: Period during which the controller will not detect an alarm after a chaperone code
is entered. This period can be set between 1 and 255 seconds.
Example: Chaperone period of 45 s: 9001 E 45 E
Once the door has been opened and closed the controller returns to surveillance mode and the
chaperone time is cancelled.
9002 Chaperone code: Code that must be entered when the system is in surveillance mode in order for the
exit to be crossed with a wristband without an alarm being triggered. This code can be between 1 and
5 digits long. Avoid using codes that start with "90" so as to avoid any of the parameter settings being
changed by mistake.
Example code 12345: 9002 E 12345 E
9003 Acknowledgement code (standalone mode only): Code that must be entered in order to
acknowledge an alarm and stop the buzzer from sounding. This code can be between 0 and 4 digits
long.
Example code 456: 9003 E 456 E
9004 Buzzer volume: Sound level of the buzzer output in the event of an alarm. 0 = no audible signal,
1 = medium volume (75 dB A at 10 cm), 2 = high volume (85 dB A at 10 cm).
Example: Setting the buzzer to medium volume.: 9004 E 1 E
PARAMETER SETTING
Commissioning (continued)
Important: The system must be in parameter setting mode before codes are entered on the keypad. There are
two ways of doing this:
- By placing a magnet under the controller.
- By entering the access code in the keypad parameter setting mode (9039E). This code is only taken into
account if the locking configuration (CONF) is at position "1.2" (factory position 2 and 3) .

17
Code Parameter
9005 Mode change mechanism: Allows the user to choose whether the changeover from intruder mode to
surveillance mode is performed by entering codes on the keypad (value 1) or by analysing the mode
selection input (value 0).
Example: Mode selection by entering codes on the keypad: 9005 E 1 E
9006 Locking control: Operation with locking control (value 0) or with release control (value 1).
Example: Electric release connected to the locking control: 9006 E 1 E
9009 Surveillance activation for the radio receivers: Enable (value 1) or disable (value 0) this function.
The green indicator light flashes when this option is enabled and the link with a radio receiver is broken.
Example: Disabling the radio surveillance function: 9009 E 0 E
9010 Adding a wristband number to the surveillance chart: Adds the number stated to the list of
wristbands to be kept under surveillance. The chart may contain 50 numbers.
Example: Adding the number 123 to the list of wristbands to be kept under surveillance: 9010 E 123 E
9011 Deleting a wristband number from the surveillance chart: Removes the number stated from
the chart of numbers under surveillance. If the number to be removed is 0 then all the numbers are
deleted.
If there are no numbers in the chart then the system is open, i.e. detections from all the wristband
numbers are acknowledged.
Example: Deleting the number 123: 9011 E 123 E
Example: Deleting the chart: 9011 E 0 E
9012 Door contact: Using a normally closed (value 0) or normally open (value 1) door contact.
Example: Connecting a normally open door contact: 9012 E 1 E
9013 Setting a time delay for the door contact: Period in seconds that the door contact is still considered
active following its return to the initial status. This period can be programmed for between 1 and 30
seconds. This period is equal to 5 seconds by default.
Example: 10-second time delay: 9013 E 10 E
9014 Immediate restart for the alarm: When this option is confirmed (value 1) an escape alarm can be
restarted immediately following acknowledgement of the alarm. Otherwise the wristband has to leave
the detection zone for at least 20 seconds before a new escape alarm is possible again from this
number.
Example: Immediate restart for authorised alarm: 9014 E 1 E

18
SETTING THE ANTENNAE
Due to the low power level radiated by the wristband transmitters setting the sensitivity level of the antenna must be
carried out under conditions that are as close as possible to normal system usage.
Proceed as follows in order to set the antenna:
• Set the thumbwheel SW1 to 8, which corresponds to medium sensitivity for the receiver.
• Set the antenna to test mode by placing the congurator ST2 to 2-3
• Fit a wristband in exactly the manner as is worn by the residents (for example, on your right wrist)
• Remove all other wristbands from the system in order to prevent any interference. Place them in standby mode
or put them in a metal box or enclosure.
• Adjust the sensitivity of the antenna using the thumbwheel SW1 so that you will be detected once inside the
desired area. The detection and reception level in relation to the threshold defined by SW1 are indicated by the
antenna indicator lights flashing (see below). Make allowance for a safety margin in order to ensure detection
even if a wristband's radio range is altered (if an unusual obstacle is present for example).
The value 0 corresponds to the receiver's minimum sensitivity level, i.e. the transmitter must be very close
in order to be detected (in the order of a few centimetres). The higher the thumbwheel value the greater the
detection distance. The value F corresponds to the acknowledgement of any signal received that is correctly
decoded.
• Exit the test mode by resetting the congurator ST2 to position 1-2
• Perform one or more trigger tests in normal mode
Illuminated signals in test mode.
• Green indicator light DS4
- On continuously: Awaiting reception
- Off for 200 ms: Receiving wristband
• Red indicator light DS2
- Off: No reception or level below that determined by SW1
- 100 ms pulse: Reception with a level slightly higher than the threshold determined by SW1
- Two 100 ms pulses: Reception with a level much higher than the threshold determined by SW1
