4.11.2 Auxiliary Power Installation
NAC Circuits 1and 2 on the control panel can be used as auxiliary power circuits. The four types of auxiliary
power available are:
• Door Holder (see section 4.11.2.1)
• Constant (see section 4.11.2.2)
• Resettable Power (see section 4.11.2.3)
• Sounder Sync Power (see Section 4.11.2.4)
Auxiliary power circuits are power limited. Each circuit can source up to 2.5A (total current for system must not
exceed 2.5A).
To install an auxiliary power circuit:
1. Wire the NAC circuit(s) that will be used for auxiliary power. See Figure 3-2 for location of NAC circuits.
2. Configure the auxiliary power output through programming (see section 7.5).
4.11.2.1 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 27.4 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.
