SelecTone® Speaker amplifier is designed to produce crisp, clear tones, digital voice messages and live public address. Designed to mount in ceilings, the 50GCB features a seven-inch white grille over a 4 inch speaker amplifier. Internal gain control allows output adjustment from 64 dBA to a maximum of 88 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 TM33 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, a SelecTone® command unit or a CommCenter® digital message center. SelecTone® command units and CommCenter® digital message centers can broadcast tones, voice messages, melodies and live public address to an unlimited number of SelecTone® speaker amplifiers.
