Installing External 12-30 VDC Power Supply
Alarm Condition: If the unit is activated in the event of an emergency (depression of
the operating element) it will immediately emit an alarm tone for the duration selected,
an activation flag will drop into view and the LED will flash red every 8 seconds until the
unit is reset.
Resetting Unit:
1. DIL switch settings: changes will only take effect when the unit has been powered
back up using the master key switch.
2. Silencing Alarm : If the operating element has been depressed the reset Key is to
be used to reset the unit, returning it to Standby Mode.
Note:
the master key switch can be used to silence the alarm but this will turn the unit ‘OFF’
and the alarm will continue to sound when the unit is turned back `ON’.
Power Loss: In the event of any loss of power, the LED will turn red and emit a short
beep every 90 seconds. The unit will still run safely using the 9 VDC battery as a back
up. As soon as power is restored the unit will automatically return to the `standby’
condition.
Low or No Battery: If the unit is reset but the battery is at low power or not attached a
fault will be indicated – the LED will turn red and the unit will emit a short single
beep every 90 seconds.
The unit automatically checks for low battery status every 16 minutes, during this
period if the battery falls into low battery condition (or is disconnected in the presence
of an external power source), the LED will turn red and emit a short beep every 90
seconds upon detection at the end of any 16 minute cycle. The battery will either need
replacing or reconnecting and the unit reset before it will return to a standby condition.
Step 1.
Ensure that the unit is switched ‘OFF’.
Step 2.
Insert the external power wires into the correct terminals.
Step 3.
Connect the 9 VDC battery. The battery must be fitted as it
will become a backup if there is a power failure.
Step 4.
DIL switch SW4 – should be `ON’ (external power required).
Step 5.
Turn the unit `ON’ using the master key switch.
Step 6.
The LED will illuminate to a constant green indicating that the unit is functioning correctly.
