Controlling Four NACs With One Input and Selective Silence
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.
Notes: The following notes apply to Figure 5.1 on page 29.
1.
When the HPF24S 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.

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 (7 & 9) 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.
