Specification.IN3 Input from a movement detector such as a PIR (Normally Closed
The MAYDAY is a loneworker 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 keyswitch 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.
5 . An integral piezo sounder. (85db at 10cm)
6. 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 keyswitch or other device. (Normally
Closed - open to start lone working)
-open on detection - ie 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 keyswitch 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 keyswitch 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.
Loneworker 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 particular 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 keyswitch is thrown to activate ie arm the MAYDAY the
four red System Active countdown LEDs adjacent to the OK button
illuminate and the countdown timer T1 starts. If the keyswitch 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.

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)
8.Under mains fail condition the green power on LED will
extinguish.
9. If 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 reprogrammed 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 commom 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
eg ENT. The LCD display readings are denoted in bold italics eg 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: ENT1-4 : OR O-D. Press 0
and 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 ENT1-4 : 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: ENT1-4 : OR O-D, press 1 to 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 2 to programme the second telephone number to be
dialled followed by it's 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, A
button to correct.
4.3.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 7 the 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 numbers 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 B repeatedly 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 0 and 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 B button 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 8 to 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 B the 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)
10.1.From READY press ENT. The display will alternate between: ENT 1-4 : OR O-D. Press ENT again and the display will show ERASE- press B twice to scroll
the display to show PHONES. Press ENT to accept and the display should revert
to READY. You will now need to re-programmed the numbers as in 4 above.
Pressing ESC from display READY should display SD1+. To get back to the
READY display, enter the passcode 1234. To return to the SD1+ wait for 60
seconds or repeatedly press ESC. Other options such as changing the passcode
or setting up the BT line as pulse or tone should be done from the SD1+ operating
manual.
