Model 450E Electronic Horn
Safety Message to Installers and Users
People’s lives depend on your safe installation of our products. 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 the National Electrical Code and/or Canadian
Electrical Code and will follow the NEC and/or CEC Guidelines as
well as all local codes. This horn should be considered a part of the
warning system and not the entire warning system.
The selection of the mounting location for this horn, its controls
and the routing of the wiring are 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,
operating, or maintaining 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 horn. You should ensure that the
front of the horn 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. The OSHA Code of Federal Regulations
1910.95 Noise Standard provides guidelines which may be
used regarding permissible noise exposure levels.
• After installation, ensure that all mounting screws are
tightened.
• Establish a procedure to routinely check the signal system for
proper activation and operation.
