Power input and detector output ports are protected by separate fuses
The relay board has 3 relay outputs:
Port Usage
Fault Fault Relay output
AL1 Alarm 1 Relay output
AL2 Alarm 2 Relay output
Alarm relays have 3 pins grouped on board to adjust NO/NC option. The relay output pin
positions shown below:
The analogue module must be setup using AN2 configuration tool to define target addresses for
analogue detectors and adjust alarm levels for the relays.
