12.8 8 Way Relay Board
The Relay Board (BRD25EWRB) 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.
All terminal points are protected.
The board switches the relays as determined by the panel. The relays can be controlled by:
 Zones Alarm
 Group Alarm
 Device Alarm
 Internal Output
 Panel Output
 Loop Output
 Panel Input
 Loop Input
 Reset – relay is activated for 3 seconds when reset depressed
