3.4.4.1 Door Holder Power
Door holder is intended for fire door applications. When there are no alarms in the system and
the panel has AC power, door holder circuits have 24-volt power present at their terminals.
Any alarm will cause power to discontinue. Power will be re-applied when the system is reset.
If AC power is off for more than 15 seconds the auxiliary door holder power will be
discontinued to conserve the battery backup power. When AC power is restored, power is
immediately restored to the door holder circuits.
3.4.4.2 Constant Power
Use constant power for applications that require a constant auxiliary power source. Power is
always present at Constant circuits.
3.4.4.3 Resettable Power
Resettable power is typically used to power beam detectors, flame detectors, and conventional
4-wire smoke detectors. For circuits selected as Resettable, 24-volt power is always present at
the terminals unless a system reset occurs. If a system reset occurs, power is removed from the
terminals for 30 seconds, then re-applied.
