INSTALLATION INSTRUCTIONS FOR VIBRATONE HORN MODEL 350WBX
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.
