Model 5496 Intelligent Power Module Installation and Operation Manual 151276-L8

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.
3.4.4.4 Sounder Sync Power
Sounder Sync Power continuously outputs the System Sensor synchronization
pattern and is intended for use with B200S sounder bases
