Installation and Maintenance Instructions
Models 304X and 314X Explosion-Proof Amplified Speakers
The speaker cone and projector are constructed of rugged spun
aluminum. The solid-state amplifier 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.
Unpacking the Speaker
After unpacking the horn, examine it for damage that may have
occurred in transit. If the horn has been damaged, do not attempt to
install or operate it. File a claim immediately with the carrier, stating
the extent of the damage. Carefully check all envelopes, shipping
labels, and tags before removing or discarding them. Disposal of all
shipping materials must be carried out in accordance with national
and local codes and standards. If any parts are missing, please call
Federal Signal Customer Support at 708-534-4756 or 877-289-3246.
