A short circuit causes themodule to inhibit the activation of the audible/visual signal circuit so theriser is not connected to the wiring fault. Upon command from thecontrol panel, the module connects the output circuit to the riser input.The output circuit energizes a riser to operate polarized audible andvisual signals. The module can be used for connection of a Class A orClass B (with EOL) output notification appliance circuit (NAC).The device address is set using the two rotary switches located on thefront of the module. One device address is required.The module is configured to operate as a GenesisAudible/Visual/Silence device type from the factory. The module canalso be configured for other device types through front panelprogramming or the configuration utility. Refer to the applicable controlpanel technical reference manual for a list of available device types.Genesis Audible/Visual/Silence: Used with Genesis and EnhancedIntegrity horns and strobes.
