AD Description
Federal Signal SelecTone® EM3 Extension Module, For Use With Series 50GC/300/300GC/302GC Signaling Device, -31 to 151 deg F, NEMA 3R Enclosure, UL/cUL Listed, Die Cast Aluminum, Gray
Vendor Description
Model EM3 SelecTone® extension module is designed to add multi-tone capability to an individual SelecTone® unit and can be used with models 50GC, 300, 300GC and 302GC. The die cast aluminum alloy housing has the same dimensions as the main amplifier housing of the above mentioned models and is sealed with gray enamel paint. The EM3's internal components are protected from the elements by dust and moistureproof seals. Its internal components are a wiring terminal strip, edge connector slots for three model UTM tone modules and an interface to connect to a SelecTone® 300, 300GC or 302GC signaling device. The EM3 is not compatible with the TM33 tone module. With the EM3, three functions can be simultaneously monitored rather than one. Tone activation and selection is accomplished by user supplied, normally open dry contacts. Where voice communication is not necessary and the application requirements dictate up to three tone signals, the EM3 extension module allows a single SelecTone® audible signal to fill those needs.
