The selection of the mounting location for this horn,

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 for 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.
• Any maintenance to the unit MUST be performed
by a trained electrician in accordance with NEC
Guidelines and local codes.
