Federal Signal's Model 302GCX SelecTone 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 aluminum. The amplification circuitry, tone module, and gain control are contained in a housing constructed of die-cast aluminum. All surfaces are sealed with powdercoat paint. Dust and moisture proof gaskets provide protection from the elements. Internal gain control allows output adjustment from 0dBa to a maximum of 114dBa at 10 feet.
The 302GCX is UL Listed for Class I, Division 2, Groups A, B, C and D; Class II, Division 2, Groups F & G, and Class III. It has been tested and approved for use in Type 4X applications.
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 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/dismissal, public address, and process control signaling.
