Applications
The control module is shown to demonstrate the use of a remotely 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 NAC.

6 = ON
7 = OFF (charger enabled)
8 = OFF (circuit 4 NAC function)
*If the SLC device does not match the one in this figure,
refer to the SLC manual wiring conversion charts for
legacy and newer versions of the modules.
The following notes apply to Figure 5.1 on page 28.
1. When the HPF-24S power supply is in an inactive state (control module not active), a trouble
on the power supply will result in an open circuit condition on the control module output
circuit (monitored by End-of-Line Resistor across TB4, Terminals 5 & 6). As an alternative,
the trouble contacts at TB5 of the power supply can also be used for independent trouble
monitoring.
2. The addressable relay module must be programmed as a silenceable point at the FACP to allow
selective silence of horn/strobe devices. The Normally Open contact of the relay module is
connected between TB4 Terminal 7 (IN2 +) and Terminal 9 (Aux. Power +).
3. Do not loop wires under screw terminals. Break wires to maintain proper supervision.
4. An End-of-Line Resistor must be installed between TB4, Terminals 5 & 6 for control module
wiring supervision (the ELR value is dependent on the module employed).

HPF24S Series Power Supplies — P/N 52751:E1 4/14/2011
HPF24S has been set for
Selective Silence and Relay
Module has been programmed
at FACP as a silenceable point
so it can perform selective
silence when its Normally Open
contact (8 & 10) closes in
alarm, then opens when silence
is invoked at the FACP.
Note: the Relay Module can be
mounted on the power supply
inside the cabinet. This allows
power wiring to remain inside
the cabinet.
