SAFETY MESSAGE TO INSTALLERS

NOTE

INSTALLATION, MAINTENANCE AND DISPOSAL OF THIS PRODUCT MUST BE

CARRIED OUT IN ACCORDANCE WITH NATIONAL CODES AND STANDARDS.

It is important to follow all instructions shipped with this product. This device is to be installed by a
trained electrician who is thoroughly familiar with and will follow all applicable national and local
codes in the country of use.

The selection of the mounting location for the device, its controls and the routing of the wiring is to
be accomplished under the direction of the Facilities Engineer and the Safety Engineer. In addition,
listed below are some other important safety instructions and precautions you should follow:

• Read and understand all instructions before installing or operating this equipment.

• Do not connect this unit to the system when power is on.

• Optimum sound distribution will be severely reduced if any objects are in front of the speaker.
You should ensure that the front of the speaker is clear of any obstructions.

• All effective warning horns produce loud sounds which may cause, in certain situations,
permanent hearing loss. The device should be installed far enough away from potential listeners
to limit their exposure while still maintaining its effectiveness. National Noise Standards, such as
The OSHA Code of Federal Regulations 1910.95 in the United States, provide guidelines which
may be used regarding permissible noise exposure levels.

• After installation, ensure that all mounting screws have been tightened.

• Establish a procedure to routinely check the sound system for proper activation and operation.

• Provide a copy of these instructions to the Safety Engineer, operator(s) and maintenance
personnel.

• File these instructions in a safe place and refer to them when maintaining and/or reinstalling the
device.

Failure to follow all safety precautions and instructions may result in property damage, serious
injury, or death to you or others.

A. Introduction.

In all installations, it is recommended that the electrical wiring to the installation site be
completed before the horn is mounted. Installations are subject to national and local

electrical and fire codes and standards.

B. Installation.

WARNING

Do not connect wires when power is on.

The 350WB is gasketed and has two 3/4-14 NPT and one 1/2-14 NPT tapped openings to

2. See figure 1. Remove and retain the four screws which secure the horn to the rear
enclosure. Remove the horn from the rear enclosure.

block is capable of accepting both solid and stranded wire within the range of 10 AWG
(5.27 mm sq.) to 20 AWG (0.52 mm sq.). When using stranded wire, ensure that the
strands of the wire are twisted together prior to inserting them into the terminal block.

4. Reassemble the horn to the rear enclosure using the previously removed screws.

5. For Model 350WB-120VAK only:
a. Volume adjustment set screw is already installed in horn.
b. For additional information, see instruction sheet 8435A536.

SAFETY MESSAGE TO MAINTENANCE PERSONNEL

• Read and understand all instructions before performing any maintenance to this unit.

• To reduce the risk of electrical shock or ignition of hazardous atmospheres, do not perform
maintenance/service on this device when circuits are energized.

• Optimum sound distribution will be reduced if the speaker becomes clogged with a foreign
substance. Periodic checks should be performed to ensure foreign substances are not packed into
the speaker.

• Any maintenance to the warning system must be performed by a trained electrician in accordance
with all applicable national and local codes and standards in the country of use.

• Never alter the unit in any manner. Safety in hazardous locations may be endangered if additional
openings or alterations are made in units specifically designed for use in these locations.

• The nameplate, which may contain cautionary or other information of importance to maintenance
personnel, should not be obscured if the exterior of housings are painted.

Failure to follow all safety precautions and instructions may result in property damage, serious
injury, or death to you or others.
