INSTALLATION Proper installation of the unit is essential for years of safe, reliable operation. Please read all instruction before installing the unit. Failure to follow these instructions can cause serious damage to the unit or vehicle and may void warranties. SAFETY PRECAUTIONS For the safety of the installer, vehicle operator, passengers and the community please observe the following safety precautions.
FUSE Auxiliary Input Function - The auxiliary input normally activates the Horn function. To activate the Man/Phsr function with the auxiliary input cut the jumper resistor labeled "AUX I". T-T AUX P CUT P PHSR AUX I INSTALLER-SELECTABLE OPTIONS Carefully cutting programming resistor jumpers or traces on the printed circuit board inside the case can select various options. The cover must be removed to access the jumpers. The cover is held in place by a snap-fastener on the back of the unit.
ELECTRICAL CONNECTIONS Disconnect vehicle battery before making any electrical connections. Make electrical connections with supplied terminal block plug for siren functions and spliced lead wires for light control outputs. Wiring is not supplied. Wire Size and Termination - The diagram shows the minimum wire size used for each connection, along with recommended lead color. If the wire is longer than 10 ft. use the next larger wire size.

Light Control Connections In addition to these instructions a label located on the bottom of the unit shows the light control switch connections. Fuses / Breakers The lighting control circuits of this unit are not fused. Automotive fuses or circuit breakers must be connected between the power source and the unit properly rated for the circuit requirements. Failure to install proper circuit breakers or fuses can result in damage to the unit and/or vehicle.
Light Control Rocker Switch Connections The following diagram shows proper connection of the rocker switch leads located at the rear. Note: Negative (NEG) connection must also be made on 10-Pin connector for rocker switches to light up. WARNING: The lighting control circuits of this unit are not fused. Automotive fuses or circuit breakers must be connected between the power source and the unit properly rated for the circuit requirements.
OPERATION Sound Hazard - Sound level from siren speaker (>120dBA @ 10 feet) may cause hearing damage. Do not operate siren without adequate hearing protection for you and anyone in immediate vicinity. (Ref. OSHA 1910.95 for occupational noise exposure guidelines) SIREN CONTROLS Two 3-position rocker switches control the primary operating modes of siren. These modes are as follows: YELP STBY WAIL ON OFF RAD On: Applies power to the siren system for operation independent of light control system.
Auxiliary Input During installation an auxiliary input may be connected to the horn ring or other switching device. It provides the same operation as pressing the Horn button or optionally the Man/Phsr button. Cutout During installation a cutout input may be connected to a door switch. It turns off any siren tone when the door is opened. The siren tone will continue to be cut off even when the door is closed. Changing any siren control switch or input will restore normal function.
SERVICE This unit is designed to provide years of reliable service under even the worst conditions. Many times there may appear to be a problem with the unit when the true problem is in the speaker(s), controlled devices, or improper installation. The following chart shows typical symptoms and possible causes. A blown internal siren fuse doesn't necessarily mean that the unit is bad. If a speaker or speaker lead is shorted this fuse will blow before the unit is damaged.
