An Overview of the Speakers
The Federal Signal Model 304X and 314X Explosion-Proof
Amplied Speakers are designed to produce crisp, clear tones in
supervised alarm notication systems. Both models are compatible
with re alarm, voice evacuation, suppression supervised control
panels, and power boosters.
These amplied 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 Federal Signal
Connector Cards (AM25CK or AM70CK) interface with the Vrms of
the EVAC panel.

7
Installation and Maintenance Instructions
Models 304X and 314X Explosion-Proof Amplied Speakers
The speaker cone and projector are constructed of rugged spun
aluminum. The solid-state amplier circuit is protected in a die-
cast 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 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 the area.
This equipment is suitable for use in Class 1, Division 1, Groups B, C,
D; Class I, Division 2, Groups A, B, C, D or non-hazardous locations
only.
