4.3.6 Relays
The relays, located on the main processor card, interface to the Fire Alarm Control Panel (FACP)to
communicate faults, alarms and disabled states. The relays can be programmed using Xtralis VSC. Relays 3
and 6 are permanently set for Urgent Fault and Fire 1 respectively. Table4-22 below illustrates the default
assignments of functions (conditions) to relays and summarizes the default behavior of each relay. Section
5.5.10 describes how to configure the relay behavior using Xtralis VSC. It is possible to assign more than one
condition to a relay.
Fire 1 Relay
If a detector relay is to be used to signal fire alarm to the Fire Alarm Control Panel (FACP) then the Fire 1 relay
must be used.
Fault and Fire 1 Relay Terminals
The Urgent and Minor Fault relays are energized during normal operation while the Fire 1 relay is only
energized when a Fire 1 is detected. The operation of the relays are summarized in the following table.
