Controlling NACs, Aux Power, or Door Holders Using a Control Module
B.3 Controlling NACs, Aux Power, or Door Holders Using a Control Module
All output circuits, NACs, aux power (non-resettable power – active regardless of control module state), or door holders, can be controlled
from one input such as an addressable control module as illustrated in Figure B.3. The control module can be powered from one of the HPF-
PS output circuits, as 24 VDC power. In this example, Output #1 will be configured as 24VDC non-resettable aux power.
The control module is shown to demonstrate the use of an internally mounted device associated with an addressable fire alarm control panel.
The module could be replaced with any circuit capable of polarity reversal, such as an FACP Notification Appliance Circuit.

The following notes apply to Figure B.3.
•
Any output circuit can be configured as NAC, door holder, or 24VDC power.
•
Wire NACs as shown on page 14.
•
Refer to Section 3 for instructions on setting the DIP switches.
•
When the HPF-PS power supply is in an inactive state (control module not active), a trouble on the NAC circuits mapped to TB5 will
result in an open circuit condition on the control module output circuit (monitored by an End-of-Line Resistor across Terminals 1 and
4). Additionally, the trouble contacts at TB1 of the power supply can also be used for limited trouble monitoring excluding output faults
reporting to Command Input #1. Refer to Section 5 for more information.
•
Do not loop wires under screw terminals. Break wires to maintain proper supervision.
•
An End-of-Line Resistor must be installed between terminals 1 and 4 for control module wiring supervision (the ELR value is
dependent on the module/FACP employed).
•
For a list of compatible devices, refer to the HPP Device Compatibility Document #54399.
•
Refer to the SLC Wiring Manual for more information.
