Audiovox AA-939 Automobile Alarm User Manual


 
TESTING THE VOLTAGE SENSOR:
1. Arm the alarm system by pressing button
#1 of a programmed transmitter one time.
The siren will chirp once confirming that the
system is armed.
2. Wait 4 seconds to allow the unit to stabilize.
3. Open any light activated entry point, the
siren will immediately trigger.
4. Turn the alarm system off by pressing button
#1 of a programmed transmitter one time.
5. Repeat the above procedure for each light
activated entry point.
If the unit fails to operate review the following
section concerning voltage sensor adjustment.
VOLTAGE SENSOR:
In most instances, connecting the Red siren
wire to the vehicle battery will provide adequate
voltage sensing. If your vehicle does not trig-
ger when the door is opened and the interior
light turns on, it may be necessary to increase
the voltage sensor's level of detection. Before
making this wiring change, confirm that the
interior light is in good working order and
illuminates when any door is opened. If your
interior light works properly, and the unit does
not trigger, the Red wire will have to connect
to a +12 volt source closer to the interior light.
This may necessitate moving the Red wire to
the interior of the vehicle and connecting to
the interior light fuse. Routing the Red wire
through a firewall grommet and connecting to
the interior light fuse may be beyond the scope
of your automotive wiring experience. If you
are uncertain of this procedure, consult your
dealer or qualified mechanic before attempting
to re-wire the voltage sensor RED wire
through the firewall to increase the voltage
sensor's level of detection.
TESTING THE SHOCK SENSOR:
NOTE: The shock sensor incorporated in your
AA-939 security system operates on
two levels in any sensitivity range. The
warn away (pre-detect) stage oper-
ates at 30% less shock (vibration)
than the full trigger stage.
1. Arm your security system and allow the unit
to stabilize.
2. Strike the windshield support pillar with the
palm of your hand, the unit will emit a short
chirp from the siren. This is the warn away
(pre-detect) stage.
3. Striking the support pillar firmly will cause
the siren to sound. This is the full trigger
stage.
4. Repeat the above procedure from various
support areas of your vehicle, Bumpers, B
Pillars, etc.
If your system fails to operate as described,
review the following section concerning shock
sensor adjustment.
SHOCK SENSOR ADJUSTMENT:
The shock sensor of the AA-939 security
system is electronically adjusted and is capable
