Appendix B: Application Examples
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 FL-PS output circuits, configured as aux power (24VDC).
The following notes apply to Figure B.1.
When the FL-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 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).

Fire•Lite Device Compatibility Document #
15384.
