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. Failure to follow all safety precautions and instructions may result in property damage, injury or  
death.  
Qualifications - The installer must have a firm knowledge of basic electricity, vehicle electrical systems and  
emergency equipment.  
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)  
Mounting - Mount the control head for easy access by the vehicle operator. DO NOT mount in air bag deployment  
area. Assure clearances before drilling in vehicle.  
Wiring - Use wiring capable of handling the current required. Make sure all connections are tight. Route wiring to  
prevent wear, overheating and interference with air bag deployment. Install and check all wiring before connection to  
vehicle battery.  
Testing - Test all siren functions after installation to assure proper operation. Test vehicle operation to assure no  
damage to vehicle.  
Keep These Instructions - Keep these instructions in the vehicle or other safe place for future reference. Advise the  
vehicle operator of the location.  
AMPLIFIER MOUNTING  
Choose a mounting location in an area such as the driver compartment firewall, under a seat, etc. Mounting the  
amplifier in the engine compartment or in an area directly exposed to weather is not recommended. Assure adequate  
ventilation to prevent overheating. Consider wire routing and access to connector. Install amplifier to vehicle using  
1/4" hardware (not supplied).  
May need to set RADIO VOLUME ADJUST on side of amplifier before final mounting and installation.  
May also need to set POWER OUTPUT ADJUSTMENT on inside of amplifier.  
CONTROL HEAD MOUNTING  
Select a mounting location in an area such as the dash or overhead console. Choose a mounting location convenient  
to the operator and away from any air bag deployment areas. Consider wire routing and access to connections, as  
well as microphone bracket placement.  
A microphone clip along with mounting screws (CP3633) holds the microphone in place.  
FLUSH MOUNT  
The flush mount control head requires a hole in the dash. Use the mounting template on the last page. Note that the  
template may not print actual size and may need sizing on a copier. Use #6 screws to fasten to dash.  
FLUSH MOUNT WITH EXTENDED MICROPHONE  
The flush mount control head with extended microphone is mounted the same as the flush mount except that the  
microphone cable extension will also go behind the dash. Allow room for this cable as well.

CONTROL HEAD ELECTRICAL CONNECTIONS  
All control head leads may be extended with #22 AWG or larger lead wire.  
Negative Connection (Black) - Connect to same ground or negative supply as amplifier.  
Positive Connection (Red) - Connect to positive DC supply. It is recommended that the lead be connected to the  
accessory output of the fuse block. This provides additional protection of a fused input to the control head.  
Lights (Yellow) - This lead may be connected to the dash lights or to the red power lead. Connecting to the dash  
lights will turn on the panel lights whenever the dash lights are on.  
When connected to the red lead, make sure that the ignition switch controls the power to that connection. This  
prevents the panel lights from being continuously on.  
Control (White) - Connect to white lead from amplifier. Route this lead away from radio transmitter antenna lead to  
prevent RF interference being fed to the siren amplifier.  
Auxiliary Input (Green) - Used for Siren control. Performs same function as Siren button. Connect to a normally  
open switch or to horn ring circuit. Circuit may connect to either positive or negative. When connected to horn ring  
circuit, use a SPDT switch to connect horn ring to either vehicle horn or to manual control circuit.  
NOTE: Permanent disconnection of the vehicle horn is NOT recommended.  
NOTE: Be sure to cut lead short if not used to prevent R.F. interference and insulate with electrical tape.

AMPLIFIER ELECTRICAL CONNECTIONS  
Disconnect vehicle battery before making the following electrical connections.  
Electrical connections to the amplifier are made using the wiring harness supplied. If the amplifier needs service the  
connector can be easily removed without unwiring the harness. The power supply for the amplifier must be capable of  
delivering peak currents up to 50 amps for adequate short circuit protection and reliable operation. The preferred  
source is directly at the vehicle battery. A fuse on the unit protects from overload.  
Wire Size and Termination - The diagram shows the minimum wire size used for each connection. If the wire is  
longer than 10 ft. use the next larger wire size. Use only high quality crimp connectors for installation on the vehicle.  
Negative Connection (Black) - Both leads must be used. Connect to negative battery connector or high current  
buss.  
Positive Connection (Red) - Both leads must be used. Connect to positive battery connector or high current buss. A  
power relay may be used.  
Speaker Connection (Brown) - Both leads must be used. Connect 1 lead to each terminal or lead of the speaker.  
When used with 2 speakers connect each brown lead to both speaker terminals or leads (parallel circuit). Observe  
polarity (phasing) when connecting 2 speakers.  
Control Connection (White) - Connect to white lead from control head. Route this lead away from radio transmitter  
antenna lead to prevent RF interference being fed to the siren amplifier.  
Optional Radio Input Connection (Blue) - Connect 1 lead to each terminal of the radio speaker or output connector.  
The input is isolated and polarity is not important. May need to set RADIO VOLUME ADJUST on side of unit.

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) or improper installation. The following  
chart shows typical symptoms and possible causes.  
A blown 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. Disconnect the SPKR leads and replace the fuse. If the siren emits a sound when in the  
Yelp position it is OK. Check the speaker(s) or leads for possible shorting.
