WARNING
The lives of people depend on your safe installation and
servicing of UNITROL products. It is important to read
and follow all instructions shipped with the products. In
addition, listed below are some other important safety
instructions and precautions you should follow:
Before Installation
Qualifications
•
To properly install an electronic siren you must have a
good understanding of automotive electrical
procedures and systems, along with proficiency in the
installation and service of safety warning equipment.
Sound Hazards
•
Your hearing and the hearing of others, in or close to
your emergency vehicle, could be damaged by loud
sounds. This can occur from short exposures to
moderately loud sounds. For hearing conservation
guidance, refer to federal, state, or local
recommendations. OSHA Standard 1910.95 offers
guidance on
“
Permissible Noise Exposure.”
•
All effective sirens and horns produce loud sounds,
which may, in certain situations, cause permanent
hearing loss. You should minimize your exposure
times and wear suitable hearing protection.
During Installation
•
DO NOT
connect this system to the vehicle battery
until ALL other electrical connections are made,
mounting of all components is complete, and you have
verified that no shorts exist.
•
Be sure the siren amplifier and speaker(s) in your
installation have compatible wattage ratings.
•
Wire size range from 10 ga (largest) to 20 ga.
(smallest). Do not use wire that is smaller than any
vehicle wire being cut apart. Always use a size that
can safely carry the load to be operated.
•
If Slide Switch outputs may possibly exceed 20
amps per position, utilize a circuit breaker or relay on
EACH of the Slide Switch outputs (Terminal 15, 16
and 17)
•
Connect all power (not ignition) and ground wires
directly to battery. Implementing an in-line switch
will cause all accessory outputs to energize
momentarily. Devices such as gunlocks, trunk release
etc. will be activated upon power being provided by
such a switch.
•
Sound output will be severely reduced if any objects
are in front of this speaker. If maximum sound output
is required for your application, you should ensure
that the front of the speaker is clear of any obstruction.
•
Install the speaker(s) in a location that provides
maximum signaling effectiveness and minimizes the
sound reaching the vehicle’s occupants.
1.
DO NOT
install equipment or route wiring or cord in
the deployment path of an air bag.
•
Locate the siren so the vehicle controls can be
operated safely.
•
In order for this electronic siren to function properly,
the ground connection must be made to the
NEGATIVE battery terminal.
•
When drilling into a vehicle structure, be sure that
both sides of the surface are clear of anything that
could be damaged.
•
If wiring is shorted to vehicle frame, high current
conductors can cause hazardous sparks resulting in
electrical fires or flying molten metal.
After Installation
•
After installation, test the electronic siren and speaker
system to ensure that it is operating properly.
•
Test all vehicle functions, including horn operation
and vehicle light systems, to ensure proper operation.
•
After testing is complete, provide a copy of these
instructions to the instructional staff and all operating
personnel.
•
File these instructions in a safe place and refer to
them when maintaining and/or reinstalling the
product.
Failure to follow all safety precautions and instructions
may result in property damage, serious injury, or death to
you or others.
