The Federal Signal Model 304X and 314X Explosion Proof Amplified Speakers are designed to produce crisp, clear tones in supervised alarm notification systems. Both models are compatible with fire alarm, voice evacuation, suppression supervised control panels, and power boosters.

These amplified speakers can broadcast tones generated by a Tone Card installed into the speaker (the plug–in 32–tone UTM) or by a central tone source in a voice evacuation or paging system. When live public address or voice messages are required, plug–in Connector Cards (AM25CK or AM70CK) interface with the VRMS of the EVAC panel.

The speaker cone and projector are constructed of rugged spun aluminum. The solid–state amplifier circuit is protected in a diecast aluminum housing. Dust– and moisture–proof gaskets provide protection from the elements. All external surfaces are sealed with gray powder coat paint. A heavy–duty swivel mount bracket allows the installer to direct the output effectively.

The 304X and 314X are UL Listed for Class I, Division 1, Groups B, C and D.

The rugged construction and high output of the Model 304X and 314X make them ideal for use in harsh environments with high ambient noise levels. Both models feature an internal gain control for adjustment to suit area.
