4.9.2 Auxiliary Power Installation
NAC Circuits 1 and 2 on the control panel can be used as auxiliary power circuits.
The three types of auxiliary power available are:
• Door Holder (see section 4.9.2.1)
• Constant (see section 4.9.2.2)
• Resettable Power (see section 4.9.2.3)
Auxiliary power circuits are power limited. Each circuit can source up to 1.0A (total
current for system must not exceed 2.0A).
To install an auxiliary power circuit:
1. Wire the NAC circuit(s) that will be used for auxiliary power. See 3.5 for location of
NAC circuits.
2. Configure the auxiliary power output through programming.
4.9.2.1 Door Holder Power
Door holder power 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 disconnect. 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 disconnected to conserve the battery backup.
When AC power is restored, power is immediately restored to the door holder circuits.

Use a UL listed door holder see list from Appendix A-3, for this application.
