CHANNEL 2 OUTPUT :

This system provides an additional hardwire remote output to control an assortment of optional upgrades.
This output is an independent channel from the transmitter and is controlled by button #2 or the combination

of button 1 & 2 dependent on the programming of the transmitter as set up by your installation center. It is a
delayed ground pulse (300 mA maximum) and can be used to control:

• Optional trunk release relay AS-9256

• Optional remote starter AS-9075

INSTALLATION OF MAJOR COMPONENTS:
CONTROL MODULE:

Select a mounting location inside the passenger compartment (up behind the dash) and secure using two
screws provided.

The control module can also be secured in place using cable ties.
Do not mount the control module in the engine compartment, as it is not waterproof. You should also avoid

mounting the unit directly onto factory installed electronic components. These components may cause RF
interference, which can result in poor transmitter range or intermittent operation.

SIREN:

Select a mounting location in the engine compartment that is well protected from access below the vehicle. Avoid
areas near high heat components or moving parts within the engine compartment. To prevent water retention,
the flared, or opened end, of the siren must be pointed downward when mounted. Mount the siren to the selected
location using the screws and bracket provided.

HOOD OR TRUNK PIN SWITCH:

A pin switch is included for use in protecting the hood or trunk (or hatchback) of the vehicle.
The switch must always be mounted to a grounded, metal surface of the vehicle. It is important to select a location

where water cannot flow or collect and to avoid all drip “gutters” on hood and trunk fender walls. Choose locations
that are protected by rubber gaskets when the hood or trunk lid is closed.

The pin switch can be mounted using the bracket provided or direct mounted by drilling a 9/32" diameter
mounting hole.

Keep in mind that when properly mounted, the plunger of the pin switch should depress at least 1/4" when the
hood or trunk lid is closed.

DASH MOUNTED LED:

A small red LED is included that will serve as a visual indicator of the alarm status. It should be installed in the
dash, located where it can be easily seen from outside the vehicle, yet not be distracting to the driver.

Once a location has been selected, check behind the panel for wire routing access and to confirm the drill will
not damage any existing components as it passes through the panel.

Drill a 1/4" diameter hole and pass the red and blue wires from the LED through the hole, from the front of the
panel. Firmly press the body of the LED into the hole until fully seated.

SHOCK SENSOR:

Select a solid mounting surface for the shock sensor on the firewall inside the passenger compartment and
mount the sensor using the two screws provided. The shock sensor can also be secured to any fixed brace
behind the dash using tie straps.

Whichever mounting method is selected, make certain that the sensitivity adjustment is accessible for use
later in the installation.

VALET SWITCH:

Select a desired mounting location for the switch, that is easily accessible to the driver of the vehicle.
The switch does not have to be concealed, however, concealing the switch is always recommended, as this

provides an even higher level of security to the vehicle. The switch may be mounted in or below the dash by drilling
a 1/4" diameter hole in the location. Be sure to check behind the dash for adequate clearance for the body of
the switch, and to confirm that the drill will not damage any existing components as it passes through the dash.

Route the connector and wires toward the module and plug the connector into the appropriate connector on the
module.

WIRING THE SYSTEM:

WHITE WIRE: + 12 VDC PULSED PARKING LIGHT OUTPUT ( 15 A 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.

RED FUSED WIRE - (VOLTAGE SENSING): + 12 VDC CONSTANT BATTERY SOURCE
This wire controls the sensitivity of the voltage sensing circuit, which detects the turning on of an interior light

when a door is opened. It will also detect the switching on of parking or headlamps, and in many cases will trigger
the alarm when a thermostatically controlled electronic radiator cooling fan switches on. It is recommended that
when installing this system into vehicles with electronic “after fans”, the procedure for RED FUSED WIRE -
(HARDWIRE) should be followed.

In voltage sensing applications, the closer to the battery that the red wire is connected, the less sensitive the
voltage sense circuitry will be. Moving this connection point to the fuse panel will increase the sensitivity and
connecting to the courtesy lamp fuse in the vehicle will provide maximum sensitivity of the voltage sense circuit.

RED FUSED WIRE - (HARDWIRE): + 12 VDC CONSTANT BATTERY SOURCE
When hardwiring the control module to pin switches at all entry points, the voltage sense circuit must be disabled.

Set programming feature # 6 to the "OFF" position. Connect the red wire to a + 12 VDC constant battery source.
DARK BLUE WIRE: 300 mA PULSED OUTPUT/CHANNEL 2

The dark blue wire pulses to ground via an independent RF channel from the keychain transmitter. This is a
transistorized, low current output, and should only be used to drive an external relay coil.

WARNING:Connecting the dark blue wire to the high current switched output of trunk release circuits

or some remote starter trigger inputs, will damage the control module.

Connect the dark blue wire to terminal 86 of the AS-9256 relay (or equivalent 30 A automotive relay) and wire
the remaining relay contacts to perform the selected function of channel 2.

WHITE w/ BLACK TRACE WIRE: POSITIVE OUTPUT TO SIREN
Route this wire through a rubber grommet in the firewall to the siren location. Connect the white/black wire to

the positive wire of the siren. Secure the black ground wire of the siren to chassis ground.
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 supplies 12 VDC when the ignition key is in the ON and CRANK positions

and off when the key is in the OFF position.
