Model AA-940  
Two Button Code Learning  
Remote Alarm With Starter Inhibit  
And Two Stage Shock Sensor  
Installation & Operating Manual  
What Is Required For This Installation:  
1) A working knowledge of automotive mechanical and electrical systems.  
2) Electric Drill, 1/8” Drill Bit and (2), # 8 x 3/4” Sheet Metal Screws: To drill the mounting holes and secure  
the Siren Assembly to the vehicle.  
3) Electrical Tape: For insulating your wiring connections.  
4) (4) 6” Cable Ties: For securing the Starter Inhibit Relay and routing the harness under the hood and inside  
the vehicle’s underdash area.  
Installation Of The Major Components:  
Siren:  
Mount the Siren/Control Module in the engine compartment. The assembly should not be mounted within  
8” of any hot surface. Also consideration should be made to keep the unit away from any moving parts,  
such as the steering shaft or knuckle, as this will interfere with safe operation of the vehicle. Use the siren  
bracket as a template and mark the two mounting holes with a pencil or scribe. Drill the two holes with a  
1/8” drill bit and secure the siren assembly to the location with two #8 screws.  
LED Assembly:  
Mount the LED assembly inside the vehicle with consideration to maximize visibility from outside the  
vehicle while not causing distraction to the operator of the vehicle. The assembly can be mounted using  
the double stick tape by peeling the protective backing and placing on a clean flat surface. For mounting  
on uneven surface or area’s exposed to direct sunlight where heat may effect the double stick tape, the  
screw provided can be used to further secure the LED assembly.  
Starter Inhibit Relay:  
Mount the starter inhibit relay near the ignition switch harness under the dashboard. You will have to  
locate and cut the low current starter wire later in the installation. Secure the relay in a convenient location  
with a cable tie or tape to existing harness. Be certain the relay’s wires are accessible for making connec-  
tions later during the wiring section of this installation.  
Wiring:  
RED FUSED WIRE: + 12 VDC CONSTANT BATTERY SOURCE  
Connect the red fused wire to a + 12 VDC constant battery source capable of supplying 15 amps of current.  
This wire provides power to the unit as well as power for the parking light output.  
BLACK WIRE: CHASSIS GROUND  
Connect this wire to a solid, metal part of the vehicle’s chassis.  
Do not confuse this wire with the thin black antenna wire that exits the control module independently.  
YELLOW WIRE: + 12 VDC IGNITION SOURCE  
Connect this wire to a source that is hot when the key is in the on and crank positions, and off when the key is  
in the off position.  
WHITE WIRE : + 12 VDC PULSED PARKING LIGHT OUTPUT ( 10 AMP MAX )  
This wire is provided to flash the vehicle’s parking lights. Connect the white wire to the positive side of one of  
the vehicle’s parking lights.  
ORANGE: 300 mA GROUND OUTPUT WHEN ARMED - N. C. STARTER DISABLE  
This wire is provided to control the starter cut relay. Connect the orange wire to terminal 86 of the relay.  
Connect relay terminal 85 to an ignition wire in the vehicle that is live when the key is in the on and crank  
positions and off when the key is in the off position. ( This is where the yellow wire from the alarm should be  
connected ).  
Cut the low current starter solenoid wire in the vehicle and connect one side of the cut wire to relay terminal  
87A. Connect the other side of the cut wire to relay terminal 30.  
NOTE : This is a normally closed starter cut arrangement and when power is removed from the  
security system, the starter disable feature will not operate, allowing the vehicle to start. Audiovox  
does not recommend using the Orange wire to interrupt anything but the starting circuit of the ve-  
hicle.  
TWO PIN RED & BLACK: LED Connector  
Route the two wires from the previously mounted LED to the two pin connector of the module.  
Operation:  
Code Learning:  
In case the transmitter is lost, or you require additional transmitters, the code of the transmitter must be  
programmed into the receiver before it is capable of responding to the new or additional transmitters. Please  
perform the folowing procedure:  
 
Emergency System Override:  
If in the event the transmitter becomes inoperative while the system is armed, a method of overriding the  
alarm is required to allow you to start the vehicle.  
To override the system without the keychain transmitter:  
a) Open the vehicle door, the alarm system will sound.  
b) Turn the ignition key from off to on five times ending with the key on. After 5 seconds the unit will disarm.  
Transmitter:  
The two transmitters provided with your unit have a small 12 volt battery that will require  
replacement if the transmitter range seems to decrease, or if the unit stops working. To  
replace the battery, using a coin or flat screwdriver blade, carefully pry apart the transmitter  
case top from bottom shown. Properly dispose of the discharged battery and replace with a  
GP-23 or equivalent 12V battery. Carefully snap the two transmitter halves together paying  
attention to proper alignment so as not to damage the LED, or transmitter printed circuit  
board.  
NOTE:  
Before returning this product to the store, please call 1-800-645-4994 for any questions you may have on  
installation or customer service.
