INSTALLATION INSTRUCTIONS FOR AC AND DC VIBRATORY HORNS
People's lives depend on your safe installation of our products. It is important to follow all instructions
shipped with the products. This device is to be installed by a trained electrician who is thoroughly familiar
with the National Electrical Code and will follow the NEC Guidelines as well as local codes.
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 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.
• 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.
• 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 front of the horn becomes clogged with a foreign
substance. Periodic checks should be performed to ensure foreign substances are not packed into the
front of the horn.
• Any maintenance to the unit MUST be performed by a trained electrician in accordance with NEC
Guidelines and local codes.
• Never alter the unit in any manner.
• The nameplate, which may contain cautionary or other information of importance to maintenance
personnel, should not be obscured if exterior of housing is painted.
Failure to follow all safety precautions and instructions may result in property damage, serious injury, or
death to you or others.
