WARNING!
SIREN PRODUCTS:
This equipment is intended for use by authorized personnel only. It is the user’s responsi-
bility to understand and obey all laws regarding emergency warning devices. The user
should check all applicable city, state and federal laws and regulations.
Public Safety Equipment, Inc., assumes no liability for any loss resulting from the use of
this warning device.
Proper installation is vital to the performance of the siren and the safe operation of the
emergency vehicle. It is important to recognize that the operator of the emergency vehicle
is under psychological and physiological stress caused by the emergency situation. The
siren system should be installed in such a manner as to: A) Not reduce the acoustical
performance of the system, B) Limit as much as practical the noise level in the passenger
compartment of the vehicle, C) Place the controls within convenient reach of the operator
so that he can operate the system without losing eye contact with the roadway.
Emergency warning devices often require high electrical voltages and/or currents. Prop-
erly protect and use caution around live electrical connections. Grounding or shorting of
electrical connections can cause high current arcing, which can cause personal injury and/
or severe vehicle damage, including fire.
PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER
USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY
OF EMERGENCY PERSONNEL AND THE PUBLIC.
Unpacking and Preinstallation
Carefully unpack the unit and check the contents against the parts list on page #6 of this booklet. Report any damage to carrier
immediately.

Installation and Mounting
!
WARNING!
!
Larger wires and tight connections will provide longer service life for components. For high
current wires it is highly recommended that terminal blocks or soldered connections be used
with shrink tubing to protect the connections. Do not use insulation displacement
connectors (e.g. 3M
® Scotchlock type connectors). Route wiring using grommets and
sealant when passing through compartment walls. Minimize the number of splices to
reduce voltage drop. High ambient temperatures (e.g. underhood) will significantly reduce
the current carrying capacity of wires, fuses, and circuit breakers. Use "SXL" type wire in
engine compartment. All wiring should conform to the minimum wire size and other
recommendations of the manufacturer and be protected from moving parts and hot
surfaces. Looms, grommets, cable ties, and similar installation hardware should be used to
anchor and protect all wiring.
Fuses or circuit breakers should be located as close to the power takeoff points as possible
and properly sized to protect the wiring and devices.
Particular attention should be paid to the location and method of making electrical
connections and splices to protect these points from corrosion and loss of conductivity.
Ground terminations should only be made to substantial chassis components, preferably
directly to the vehicle battery.
The user should install a fuse sized to approximately 125% of the maximum Amp capacity
in the supply line to protect against short circuits. For example, a 30 Amp fuse should
carry a maximum of 24 Amps. DO NOT USE 1/4" DIAMETER GLASS FUSES AS THEY
ARE NOT SUITABLE FOR CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS. Circuit
breakers are very sensitive to high temperatures and will "false trip" when mounted in hot
environments or operated close to their capacity.
