4.13.5 Auxiliary Power Installation

Flexput Circuits 1-6 on the control panel can be used as auxiliary power circuits. The three
types of auxiliary power available are:
• Door Holder (see Section 4.13.5.1)
• Constant (see Section 4.13.5.2)
• Resettable Power (see Section 4.13.5.3)
Auxiliary power circuits are power limited. Each circuit can source up to 3A (total current for
all Flexput circuits must not exceed 6.0 A).
To install an auxiliary power circuit:
1. Wire the Flexput circuit(s) that will be used for auxiliary power. See Figure 4-38 for loca-
tion of Flexput circuits.
2. Configure the auxiliary power output through programming (see Section 7.5).

4.13.5.1 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 ESL DHX-1224, for this application.

4.13.5.2 Constant Power

Use constant power for applications that require a constant auxiliary power source. Power is
always present at Constant circuits.
