SelecTone® Hazardous location audible signalling device. Speaker amplifier is designed to produce tones, digital voice messages and live public address in harsh environments with high ambient noise levels. The rugged speaker cone and projector are constructed of spun aluminium. The amplification circuitry, tone module and gain control are contained in a housing constructed of die-cast aluminium. All surfaces are sealed with powder-coat paint. Dust and moisture-proof gaskets provide protection from the elements. Internal gain control allows output adjustment from 0 dBA to a maximum of 114 dBA at 10 ft. SelecTone® speaker amplifiers are used individually or as part of a plant-wide emergency notification system. The model universal tone module with 32 tones or the custom tone module is plugged into a single SelecTone® speaker amplifier for stand-alone use or into a SelecTone® command unit for plant-wide signalling. For plant-wide signalling, a connector kit is installed into each SelecTone® speaker amplifier and wired to a central controller, SelecTone® command unit or CommCenter® digital message center. Command units and CommCenters broadcast tones, voice messages, melodies and live public address to an unlimited number of SelecTone® speaker amplifiers. Applications for SelecTone® include emergency warning, evacuation, start or dismissal, public address and process control signalling.
