shipped with the products.
This device is to be installed by a trained electrician who is thoroughly familiar with the applicable
National Electric 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 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 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 siren. You should
ensure that the front of the siren is clear of any obstructions.
• All effective signaling sirens produce loud sounds, which may cause, in certain situations, permanent
hearing loss. They should be installed far enough away from potential listeners to limit their exposure
while still maintaining their effectiveness. The OSHA Code of Federal Regulations 1910.95 provides
guidelines which may be used regarding permissible noise exposure levels.
• After installation, ensure that all mounting bolts are properly tightened.
