Installation and Maintenance Instructions

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.
