in these locations.
• The nameplate, which may contain cautionary or other information of importance to
maintenance personnel, should NOT be obscured in any way. Ensure that the nameplate
remains readable.
• All effective warning sirens produce loud sounds, which may cause, in certain situations,
permanent hearing loss. Take appropriate precautions such as hearing protection.
The device should be installed far enough away from potential listeners to limit their
exposure while still maintaining its effectiveness.
• DO NOT rotate the projector more than 180 degrees or internal siren wiring may be
damaged.
• For maximum effectiveness, ensure that the front of the siren is clear of obstructions.
• After installation or maintenance, ensure that all threaded joints are properly tightened.

Installation and Maintenance Instructions
• Establish a procedure to routinely check the congured system for proper activation
and operation.
• Check the unit periodically to ensure that the effectiveness of the device has not been
reduced because it has been clogged with a foreign substance or because objects have
been placed in front of it.
Failure to follow all safety precautions and instructions may result in property damage,
serious injury, or death.

Installation and Maintenance Instructions
EXPLOSION HAZARD: To reduce the risk of re or explosion, do not install the unit
in a hazardous location if the operating temperature exceeds the hazardous atmosphere’s
ignition temperature. Before proceeding, consult the product nameplate and determine the
operating temperature of the unit.
Improper operation could occur if an accumulation of water, snow, dust, etc. resides in
the unit projector, severely reducing or preventing output of this device. Mount the unit
so unit projector is pointed horizontally or slightly downward.
1. Flat Surface Mounting
a. Select the mounting location and place rear of the housing against
mounting surface.
b. Using the mounting holes as a template, scribe drill position marks on the
mounting surface. See Figure 1 for mounting hole spacing.
Before drilling holes in any surface, ensure that both sides of surfaces are clear of items
that could be damaged.
c. Secure the unit to mounting surface with appropriate user supplied No. 10
hardware.
d. Remove cover by removing the two No. 10 x 1 ½” Phillips head screws to access
wiring compartment.
e. Route wires through the 1/2” threaded openings into the SST3GCX-MV unit in
accordance with National and Local Electrical codes. Wire size depends upon the
operating current and the distance from the power source. All electrical wiring
must be routed through approved conduit and ttings.
f. Reposition unit projector if necessary to obtain desired sound coverage. Loosen
collar nut and move projector to desired position. Tighten nut to lock projector in
place.
Electrical Connections:
To avoid electrical shock, do not connect any wires when circuits are energized.
EXPLOSION HAZARD: Do not disconnect the unit while the circuit is live or unless
the area is known to be free of ignitable concentrations. Keep the unit tightly closed when
in operation.
