• Read and understand all instructions before installing, operating, or servicing this
equipment.
• All effective warning sounds may, in certain circumstances, cause permanent hearing
loss. Take appropriate precautions such as wearing hearing protection. Maximum
sound level exposure limits specified in OSHA 29 CFR 1910 should not be exceeded.
• For optimum sound distribution do not install this speaker where objects would block
any portion of the front of the Informer.
• 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 or a Federal Signal certified
Service Provider.
• Never alter the unit in any manner.
• The nameplate should NOT be obscured, as it contains cautionary and/or other
information of importance to maintenance personnel.
• After installation and completion of initial system test, provide a copy of these
instructions to all personnel responsible for operation, periodic testing, and
maintenance of the equipment.
• 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.
Installation and Service
• After installation or service, test the system to confirm that it is operating properly.
Test the system regularly to confirm that it will be operational in an emergency.
• If future service and operating personnel do not have these instructions to refer to,
the system may not provide the intended audible warning and service personnel
may be exposed to death, permanent hearing loss, or other bodily injury. File these
instructions in a safe place and refer to them periodically. Give a copy of these
instructions to new recruits and trainees. Also give a copy to anyone who is going to
service or repair the Informer.
• To reduce the risk of electric shock, do not perform any servicing other than what
is contained in the operating instructions unless you are qualified to do so. Refer all
servicing to qualified service personnel. Always test the Informer before using after
repairs have been made.
