MAYDAY LMW2 Loner Worker Safety System
Specification
The MAYDAY is a lone worker safety system. It is designed to give audible and visual warning to prompt staff to take action
by cancelling a warning after a pre-determined period. Failure to take action will result in a secondary alarm operating after
a further pre-determined period. This is used to raise an alarm to call for assistance which can be either a simple sounder
and visual indicator or a voice message transmitted via a speech dialler (not supplied) via a landline. The two time periods
are separately adjustable. 20 - 60 minutes and 2 - 10 minutes respectively. The MAYDAY is mains powered and supplied with
a rechargeable 12v 0.8Ahr standby battery. The integral 12v power supply will deliver 150ma for ancillary items. The unit is
housed in a plastic enclosure approx. 125w x 175h x 55d (mm).
The MAYDAY has the following integral indications and controls:-
1. An On Off key switch to arm the unit.
2. An OK button to restart the countdown timer and reset the alarm.
3. A green Power On LED.
4. Four red System Active countdown LEDs.
1. 5 . An integral piezo sounder. (85db at 10cm)
5. Two adjustable countdown timer controls. These are fitted internally and only used during the installation set-up.
Five inputs are provided for connecting ancillary devices:
IN1 Remote OK buttons to supplement the front panel OK button. (Normally Open -close to acknowledge OK)
IN2 To arm the MAYDAY from a key switch or other device. (Normally Closed - open to start lone working)
IN3 Input from a movement detector such as a PIR (Normally Closed -open on detection - i.e. OK)
IN4 Input from a speech dialler. (Apply a -ve for OK)
IN5 Timer set-up. This is a divide by 60 facility (eg 57mins= 57sec).
Volt free contacts are provided by three independent relays:
Relay 1 operates when the key switch is thrown to arm the unit.
Relay 2 operates at the end of the first pre-determined run-down delay T1 (20-60 minutes).
Relay 3 (normally on, off when operated) operates at the end of the second pre-determined countdown delay T2
(2-10 minutes).
Eight outputs are provided for remote indications:
LED1 - 4 follow the LEDs on the front panel.
LED5 Remote buzzer, follows internal buzzer.
LED6 Remote LED, all indications.
LED7 Remote LED to indicate T2 has run out.
LED8 Remote power LED.
Timer Set-Up Procedure
With IN2 closed (or key switch OFF), link out IN5, LED’s 2 and 4 only illuminate. Set T1 and T2 pots approx. (Best guess).
Press the OK button, the unit bleeps and LEDs 1 and 3 only illuminates for T1 time in seconds. At the end of T1 the unit
bleeps and LEDs 1 and 2 only illuminate for T2 time in seconds. At the end of T2 the unit bleeps and reverts to LEDs 2 and 4
only. Adjust the pots accordingly and repeat until time T1 and T2 minutes are correct as indicated in seconds. Remove the
link IN5 and the unit is set to operate in minutes.

Lone Worker Scenarios where MAYDAY could be used
The notes below will assist in deciding how MAYDAY and ancillary equipment should be used and configured for any
situation. The first consideration should be; where are the responders located?

Operation
1. The green mains on LED is illuminated at all times unless the mains has failed.
2. When the key switch is thrown to activate i.e. arm the MAYDAY the four red System Active countdown LEDs
adjacent to the OK button illuminate and the countdown timer T1 starts. If the key switch is used to switch off at
any time, then no further timing or other action takes place. (This would be the case for scenario 1 above)
3. When armed the Lone Worker is expected to periodically press the OK button on the MAYDAY or an ancillary
OK/AV button within the workplace. Alternatively, if a movement detector is used to sense movement within the
workplace, then no action other than movement is required by the worker.
4. If the OK button or a remote OK button is pressed, the panel buzzer will bleep to acknowledge this. If a PIR
movement detector senses movement with the workplace, then the countdown timer is reset without any bleep.
This minimises annoyance when moving around constantly.
5. As the countdown timer runs down the four LEDs gradually extinguish to give a visual indication of time remaining.
As each LED extinguishes a bleep is heard.
6. At the end of the first countdown period only one LED remains illuminated, and the bleeps become more frequent
during the second countdown period to warn the lone worker that action must be taken to reset the countdown
timer by pressing an OK button or in the case of scenario 4 he/she will be called by mobile phone to dial 8 as an OK
7. If no action is taken before the end of this second countdown, then a full alarm condition is raised. This may be an
AV device on the same site to call the responders (Scenario 2) or a message from a speech dialler to call a remote
responder. (Scenario 3 or 4)
8Under mains fail condition the green power on LED will extinguish.
9If the mains have failed prior to arming then, on arming, the green power LED will flash for a short period and then
extinguish. The MAYDAY will continue to function, but the four red countdown LEDs will flash.
10 If the mains fails after arming then the MAYDAY will behave as though the primary countdown timer has run down
and only a short period remains before an OK button should be pressed. The MAYDAY assumes that there is a
possibility that the cause of the mains failure could be the lone worker.
The above conditions assume that the rechargeable standby battery is healthy.
Speech dialler setup for MAYDAY lone worker alarm
The notes below are our recommended set up for use with a MAYDAY lone worker alarm when connected in accordance with
our installation instructions. If you wish to set the SD1E differently then you should consult the installation and operation
manuals supplied.
The SD1E is a 4 channel 4 number speech auto-dialler. (The SD1E operators manual refers to channels as trigger inputs). The
channel inputs are A,B,C and D. Channel D is factory set as an abort channel and needs to be re-programmed as a message
channel (see 7 below). Each channel can give a different message. In the notes below a message is composed of two phrases, a
common phrase and a channel specific phrase. The common phrase is referred to as phrase O and the channel phrases as A,B,C
and D. Refer to the table below for an example of recommended phrases. Write your own phrases in a similar table before you
start recording. You have a total of 40 seconds to record all 5 phrases. It is recommended that all messages be recorded in order
in one session, to avoids trying to fit a spoken message into a predefined time slot.
Throughout these instructions the keypad presses are denoted in bold capitals e.g. ENT. The LCD display readings are denoted in
bold italics e.g. READY
1. If this is a first time install short circuit the Factory Restart pins JP2 whilst applying 12vdc power. This erases the
memory of all phrases, numbers and other set up parameters. The unit should bleep and display PLEASE RECORD.
Complete all programming before connecting the BT line.
2. Next enter the PASSCODE '1234'. The display should read READY.
3. You must now record at least one message.
3.1. Press ENT. The display will alternate between: ENT 1-4 : OR O-D. Press 0and the display will read RECORD PHRASE
0. (The 1-4 is for the telephone numbers see later). Phrase 0 is the common phrase and will be announced first in
each message.
3.2. To record the phrase press ENT and the display shows REC-40, and starts to count down. Speak your phrase into
the integral microphone of the SD1E. When you have recorded the phrase, press ESC. This will stop the timer and
the display will again alternate between ENT 1-4 : OR O-D. waiting for you to record the next phrase.

3.3. Record the phrases one at a time, to record the A phrases, press A, the display will read RECORD PHRASE A. Press
ENT and the display will show REC and the remaining time. Press ESC at the end of phrase A. While recording, the
total time remaining will be displayed.
3.4. Record phrase B by pressing B and repeating the procedure 3.3 above.
3.5. Press ESC to get back to READY display.
4. Next programme the telephone numbers.
4.1. From the READY display, press ENT the display will alternate between: ENT 1-4 : OR O-D, press 1to programme
the first telephone number to be dialled followed by the telephone number, including any access codes for PABX
system, and press ENT. The display will revert to alternating between: ENT 1-4 : OR O-D. Press 2to programme the
second telephone number to be dialled followed by its number. Repeat the process for number 3. Number 4 is
usually made available for the lone worker’s phone from which he/she can acknowledge and reset the MAYDAY. If
you get a digit wrong, press the, Abutton to correct.
4.2. Press ESC to get back to READY display.
5. Next set up the SD1+ output to acknowledge the Mayday.
5.1. From the READY display press 6. The display should read OUTPUT. Press ENT the display should read ACTIVE. Press
B until the display reads SUCCESS and then press ENT the display should read READY.
This must be used if the Mayday calls the lone worker's mobile phone to be acknowledged and reset the MAYDAY
timers.
6. Next set up the call routing. Which numbers to call for a particular channel.
6.1. From the READY display press 7the display should read ROUTE-Press ENT. The display should read A>1234. Press
the numbers 1,2,3 or 4 to toggle the display numbers on or off as required. In a typical setup telephone number 1,
2 and 3 may be toggled off for channel D, thus the display would read D>4. This is the only number that will be
called when channel D is triggered. The message sent will be the common phrase O plus phrase D
6.2. When you are satisfied that the numbers are correct for channel A the remaining channels B>1234, C>1234 and
D>1234, can be scrolled through by pressing button B. They are set up by toggling as in 6.1 above. When all are set
press ENT and the display should read READY.
6.3. We recommend that channels A, B and C call each of the four numbers 1,2, 3 and 4. Channel D should be reserved
for calling the lone worker's phone when the unit requires to be acknowledged. Thus, the routing for channel D
should read D> 4
7. Next set up the ABORT input channel as channel D. This allows the abort input terminal to be used as channel D
and also the dialler to be reset by the passcode if no one is available to acknowledge its dialled numbers.
7.1. From READY, press 8, the display should read ABORT-, press ENT and press Brepeatedly until the display reads
PASSCODE. Press ENT and the display should read READY.
8. Next set up the acknowledgement to stop the dialler from repeatedly dialling.
8.1. From READY press 0and the display should read CLRBY-press ENT and then the display should show how many
acknowledgements are required to stop the dialler re-dialling. Press the Bbutton repeatedly until you see the
number that you require, (we recommend 'ANY-1' ) and then press ENT. The display should go back to READY.
If you select the NO-ONE option, the SD1E will continue to call if numbers are engaged or not answered but will
stop when one is answered even if by an answering machine. The NO-ONE is therefore not recommended.
While it is possible to dial to a pager, it is not recommended, as the pager has no acknowledge or return call
facility. The acknowledge facility, requires the called person to press 8to acknowledge. For this reason, your
message should include the words "press 8 to acknowledge".
9. To erase the messages and start again.
9.1. From READY, press ENT, the display will alternate between: ENT 1-4 : OR O-D. Press ENT again, the display should
read ERASE-. Press Bthe display should read SPEECH press ENT and the display should revert to ENT 1-4 : OR O-D..
Press ESC to return to READY. All phrases now need to be re-recorded, see 3 above.
10. To erase telephone numbers. (assuming you are in programme mode)
