Model 302X SelecTone Speaker Amplifier is designed to meet UL 1480 intelligibility requirements producing crisp, clear tones, digital voice messages and live public address in harsh environments with high ambient noise levels. The 302X is UL Listed for Class 1, Division 1, Groups B, C and D.
The rugged speaker cone and projector are constructed of spun aluminum. The all new internal circuitry, tone module, and gain control are contained in a housing constructed of cast aluminum. All surfaces are sealed with powder-coat paint and assembled with stainless steel hardware. Dust and moisture-proof gaskets provide protection from the elements. This housing incorporates a tool-less rear cover design, eliminating the need for torque specific hardware and solves the problem of missing or lost fasteners.
Internal gain control allows output adjustment from 0dBa to a maximum of 114dBa at 10 feet. SelecTone Speaker Amplifiers 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 Speaker Amplifier for stand-alone use or into a SelecTone Command Unit for plant-wide signaling.
For plant-wide signaling, a Connector Kit is required for each SelecTone Speaker Amplifier and wired to a central controller. SelecTone Command Units and CommCenter Digital Message Centers broadcast tones, voice messages, melodies and live public address to an unlimited number of SelecTone Speaker Amplifiers. Applications for SelecTone include emergency warning, plant evacuation, start and dismissal, public address, and process control.
