wire touches chassis ground, the Printed Circuit Board and on-board relay may be damaged.
Many European imports have separate left and right side parking lights. When left & right
parking lights are on separate circuits, a pair of 6 to 10 amp diodes must be used to connect
the White wire to each parking light side. Note: Flashing the headlights is not recom-
mended. The halogen headlights found in modern vehicles are not designed to be rapidly
turned on and off. If connected to the security system, a reduction of their useful life may
be noticed. If flashing the headlights is still desired, a relay must be used, since the
headlight's current draw exceeds the 7 amp rating of the built-in relay. If flashing headlights
and parking lights are desired, use two relays - one relay will supply the parking lights and
the other relay will supply the headlights.
The Green wire's function is an open door input to the control module for vehicles having
Negative switching door pin switches. This circuit has effects on many security system
operations, the primary being the activation of the system (sounding the siren and flashing
the parking lights) if in an armed state. If the Last Door Arming and Automatic Rearming
features are utilized, after turning "off" the ignition switch and closing the door, the Last
Door Arming sequence will begin, and be suspended if a door is reopened. Opening a door
during Automatic Rearming will also suspend that feature. If the system has been
programmed to lock and unlock the doors with the ignition switch being turned "on" and

it should be noted that when arming the system with the transmitter, the user has the ability
to bypass the sensor, if desired. When bypassed, the system will not respond to either a
prewarn nor an activation trigger from the sensor. More than one sensor can be easily added
with the use of the optional Omega AU-EXP ExpandaSens
TM
module.
Optional Backup Battery Port:
This port allows the plug-in addition of an optional
9 volt alkaline battery to provide alternative power source to operate the system if power to
the control module is disconnected (the battery, wiring harness and clip-on holder is
available separately). A built-in protection circuit will not allow the 9 volt battery to back
feed voltage into the vehicle's electrical system. While on backup battery power, to conserve
the backup battery, the system will not have some functions - the Parking Light output, LED
Status Light output, the Doorlock outputs, Auxiliary Sensor output and Current Sensing
input. The Starter Interrupt will operate, when the system is armed, from battery backup,
along with the following: Aux. output and Aux. Trigger input, Negative Instant Trigger
Input, Negative and Positive Door Trigger input, and the Remote Panic feature.
Due to the
exact configuration of the security system in a particular vehicle, the operating parameters
of the system while on backup battery power will vary.
