300 SelecTone® Audible Signal
Federal Signal's SelecTone® Model 300 is a lightweight and compact, solid-state amplified speaker designed to amplify a pre-selected 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.
SelecTone Amplified Speakers are used individually or as part of a plant-wide emergency notification system. The Model UTM Universal Tone Module, with 32 tones, or the TM33 Custom Tone Module is plugged into a single SelecTone Amplified Speaker for stand-alone use or into a SelecTone Command Unit for plant-wide signaling.
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.
