Description

The Edwards FX-NAC connects a supervised output circuit to a signal riser. The output wiring – comes monitored for open and short circuits. A short circuit causes the module to inhibit the activation of the audible/ visual signal circuit. The riser – not connected to the wiring fault. Upon command from the control panel, the module connects the output circuit to the riser input. The output circuit energizes a riser to operate polarized audible and visual signals. Used for the connection of a Class A or Class B (with EOL) output notification appliance circuit (NAC).

The Edwards FX-NAC comes configured to operate as a Genesis Audible/Visual/Silence device type from the factory. It can – configured for other device types through front-panel programming or the configuration utility. Refer to the applicable control panel technical reference manual for a list of available device types.

Genesis Audible/Visual/Silence: Used with Genesis and Enhanced Integrity horns and strobes. Signals maintain synchronization per UL 1971. This configuration allows connected horns to – silenced.
