The Federal Signal E-SS series heavy duty stations are used in parking garages, elevators, correctional facilities, institutions, and secured entryways to provide single button call and duplex voice communication.

Depressing a single call button will place a call to any preprogrammed station in the system. Built-in relay contact may be activated from the connected Master station for door or camera control. The panel speaker and electret microphone provide hands-free duplex communication and a digital signal processor automatically adjusts the volume level to compensate for acoustically difficult locations.

Model E-SS series heavy duty call station faceplate is constructed of 11-gauge stainless steel with a brushed finish and furnished with a tamper resistant call switch and tamper-proof mounting fasteners. A moisture resistant speaker is protected by internal weather resistant baffles. The E-SS series station may be programmed for call destination and volume level from any master station in the system or via ECHO-SFW Windows software.
