10.1 8-Way Relay Board
The Relay Board provides 8 programmable relays with 30VDC 1 Amp voltage free change over
contacts for control or monitoring purposes and comes fitted for internal or external FACP use.
The functionality and programming of the relays is similar to the relays on the main board of the
FACP. By default the relays default to Common Alarm functionality.
Protection
All terminal points are protected.
The board switches the relays as determined by the panel. The relays can be controlled by:
Zones going to alarm
Zones going to fault
Zones Disabled
Reset – relay is activated for 3 seconds when reset depressed
