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

The following notes apply to Figure B.1.

When the PSE 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 information.

•

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 13.

•

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).

For a list of compatible devices, refer to the Notifier Device Compatibility Document #15378.
