Federal Signal's SelecTone Model 300, Series E is a lightweight and compact, solid-state audible signaling device designed to amplify a preselected tone over existing ambient noises. The speaker cone and projector are made of spun aluminum. The internal amplifier circuitry and tone module are contained in a housing of die-cast aluminum. Dust and moisture-proof gasketing provides protection from the elements. All external components are sealed with powder-coat paint.
Model 300 is designed for applications which have 250VDC power supplies. This model is UL and cUL Listed and is rated Type 3R for indoor/outdoor use.
Federal Signal's UTM (Universal Tone Module) is used with this device to generate one of 32 tones. Model 300 is designed to be used as a stand-alone, full output unit and cannot be used with a SelecTone Command System (public address is not possible).
Model 300 speaker/amplifiers are ideally suited for full output tone signaling where voice paging is not a requirement. Typical applications include emergency warning, start and dismissal, general alarm, smelters and cranes.
