B.1 Controlling NACs For Selective Silence Operation Using a Control Module

In this application, the power supply has been set as a master with synchronized outputs and selective silence (see DIP switch settings and

Selective Silence Operation information in Section 3). This application requires Input #1 to be controlled by the FACP. Input #2 is required

for controlling selective silence via a control/relay module, programmed as an alarm output and a silenceable point. Only Mass Notification,

Fire, or combo Mass Notification/Fire NACs are allowed in this configuration. The control module can be powered by one of the HPF-PS

output circuits, configured as aux power (24VDC).

The following notes apply to Figure B.1.

When the HPF-PS power supply is in an inactive state (FACP NAC not active), a trouble on the NAC circuit will result in an open circuit

condition on the FACP (monitored by End-of-Line Resistor across TB5, Terminals 1 and 4). As an alternative, the trouble contacts at TB1 of

the power supply can also be used for limited trouble monitoring excluding Selective Silence output faults. Refer to Section 5 for more infor-

mation.

•

Refer to Section 3 for instructions on setting the DIP switches.

•

Selective Silence output faults are only reported via Command Input #1 (not Command Input #2).

•

Wire NACs as shown on page 14.

•

Do not loop wires under screw terminals. Break wires to maintain proper supervision.

•

An End-of-Line Resistor must be installed across all input circuits, Terminals 1 and 4, for control module wiring supervision (the ELR

value is dependent on the module/FACP employed).
