SAFETY MESSAGE TO INSTALLERS

People’s lives depend on your safe installation of our products. It
is important to read, understand and follow all instructions shipped with
this product.

Selection of mounting location for this device, its controls and
routing of wiring should be made by the Facilities Engineer and the Safety
Engineer. Listed below are some other important safety instructions and
precautions you should follow:

• This unit must be installed by a qualified electrician in
accordance with NFPA 72, and National and local Elec­trical and Fire Codes, under the direction of the authority
having jurisdiction.

• Do not connect this unit to system wiring when circuits
are energized.

• For optimum sound distribution do not install this device
where objects would block any portion of front of speaker.

• All effective warning horns produce loud sounds which,
in certain circumstancs, may cause permanent hearing
loss. Take appropriate precautions such as wearing
hearing protection. Recommendations in OSHA Sound
Level Standard (29 CFR 1910) should not be exceeded.

• After installation, ensure that all bolts threaded joints are
tightened.

• After installation and completion of initial system test, a
program for periodic testing of this device must be
established. Refer to NFPA 72, local Fire Codes and the
authity having jurisdiction for this information.

• After installation and completion of initial system test
provide a copy of this instruction sheet to all personnel
responsible for operation, periodic testing and mainte­nance of this equipment.

damage that may have occurred in transit. If equipment has been
damaged, immediately file a claim with carrier stating extent of damage.
Carefully check all shipping labels and tags for special instructions
before removing or destroying them.

Conduit connection can be made to 3/4" threaded opening in splicing
condulet attached to this device (see figure 1).

After unpacking the horn, examine it carefully for possible

Property damage, serious injury or death could occur if this
product’s explosion-proof housing is damaged. The horn
mechanism contains no user serviceable parts. Therefore,
DO NOT loosen or remove clamp ring, which holds mecha­nism into housing, or any of the six screws on the front of the
horn grille. Loosening or removing any of these six screws
may disturb factory adjustment of horn mechanism and cause
the horn to malfunction. Attempting to remove the horn
mechanism from the horn housing may damage the horn
mechanism.

2.

Mounting Arrangements (see figure 1).

Property damage, serious injury, or death could occur if an
accumulation of water, snow, dust, etc. resides in the horn’s
grille, severely reducing or preventing operation of this device.
Mount the unit so the grille is pointed horizontally or slightly
downward.

This device can be mounted on any relatively flat surface.

WARNING

Property damage, serious injury, or death could occur if any
objects are in front of the horn’s grille, severely reducing
optimum sound distribution. For maximum effectiveness,
ensure that the front of the grille is clear of obstructions.

a. Select mounting location.

b. Using the horn as a template, scribe drill position marks
on the mounting surface. See figure 1 for mounting hole locations and
dimensions.

CAUTION

Before drilling holes in any surface, be sure both sides of
surface are clear of anything that could be damaged.

c. Drill holes at the previously scribed drill position marks
to accommodate 3/8" diameter bolts.

d. Secure the horn to the mounting surface with 3/8"
diameter hex head bolts, lockwashers, and hex nuts.

SAFETY MESSAGE TO OPERATORS

Even if your warning system is operating properly, it may not

adhered to in the installation of this device. All electrical wiring must be

National Electrical Code as well as local codes must be
routed through conduit and fittings approved for explosion-proof instal-

lations.

WARNING

Property damage, serious injury, or death could occur if
independent conductors are terminated together; both wires
of the same polarity must be used as two separate connec­tions. NFPA 72 requires that the wires be terminated inde­pendently to provide electrical supervision of the connection.

a. Remove splicing condulet cover. See figure 2. Connect
the device’s red (+) leads to the power source positive (+) lead. Connect
the device’s black (-) leads to the power source negative (-) lead.

WARNING

Property damage, serious injury, or death could occur if the
condulet cover is not closed properly. To reduce the possibility
of explosion, splicing condulet cover must be kept tightly
closed while circuits are energized.

b. Replace splicing condulet cover and tighten.

D. TESTING/OPERATING.

WARNING

Under certain conditions these devices are capable of pro­ducing sounds loud enough to cause hearing damage. Ad­equate hearing protection should be worn if standing within
close proximity to device while testing. Recommendations in
the OSHA Sound Level Standard (29 CFR 1910) should not
be exceeded.

1. After installation is complete, be sure to test the system to

verify that each horn operates satisfactorily.
