The Edwards EST GRSW is a universal room side wiring plate designed for use with Genesis LED GCS (ceiling-mount) and G4S (wall-mount) Series speakers and speaker-strobes. It allows installers to pre-mount and pre-wire the notification appliance circuit prior to installing the device, improving installation efficiency and reducing rework. The GRSW includes a shorting/diagnostics check bar to allow continuity verification of the speaker and strobe circuits before the appliance is attached. Once wiring is confirmed, the Genesis device snaps into place. The appliance can be removed from the room side without disturbing field wiring. The plate mounts to standard 2-gang or 4-inch square electrical boxes and provides in/out screw terminals supporting 12 to 18 AWG conductors.
