Alarm Relays
ATTENTION
Alarm relays are designed to operate in a failsafe mode (that is, de-energized during alarm
sate). This results in alarm actuation when power is OFF or when initially applied, until the unit
completes self-diagnostics. If power is lost to the unit, the alarms will de-energize and thus the
alarm contacts will close.
