LED Strobe / Lamp Output (Terminal 5)
An external LED Strobe/Lamp can be connected between Terminal 3 (anode +'ve) and Terminal 4 (cathode
-'ve). This 12V open-collector output mimics the internal LED Strobe/Lamp and is current limited to 20mA
with an on-board 220ohm resistor.
Relay Output (Terminal 6,7,8) - Programmable Option
As supplied from the factory the relay operates as a Fire Alarm relay, but it can alternatively be programmed
to operate as a Fault Output Relay by keying the following sequence:
Engineer Access Code-1 Select Toggle Relay Option
LEDs Off= Fire Alarm Relay*
LEDs On= Fault Relay
* Factory default setting
Note that when programmed as a Fault Output the relay is normally in a de-energised state in
order to conserve standby battery power. Total power loss will therefore not be signalled to
external equipment.
• The green Power LED flashes rapidly upon successfully entering the Engineer Access Code.
• The LEDs surrounding button indicate the current option status.
• Toggle button to set/unset the desired option.
• Press to accept OR press to quit without updating the option.
