Blue Wire - Negative Instant Trigger:
used primarily to detect entry into the hood or trunk area of a vehicle. The primary function
of this circuit is to activate the security system (sounding the siren and flashing the exterior
and interior 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, provided the Blue wire is not grounded. If the Blue wire
is grounded during Automatic Rearming, the process will be interrupted. When the Last
Door Arming feature is utilized, if the Blue wire is grounded when the last door is closed,
the Last Door Arming process will not start until the Blue wire is ungrounded.

Optional Plug-In Omega Pager Port:
Omega Pager to the security system control module. Please note that in most installations
Programmable Feature #5, Current Sensing, must be turned off to prevent false alarms by
the security system. The Current Sensing Feature, depending upon the equipment
configuration in the vehicle, may activate the system by detecting the Pager's operation.
The Omega Pager unit includes the wiring harness for direct connection to the security
system, and complete installation and operating instructions.
Plug-In Power Doorlock Interface Port:
in port for an optional doorlock interface. The 4 pin port on the system's control module
produces a negative pulse for locking the doors, a constant 12 volt pin for the optional relay

coils only, a first negative pulse for driver door unlock, and a second negative pulse for
unlocking all other doors.

The doorlock interface needed will depend upon the type of power doorlocks the vehicle
has. Note: The vehicle must have existing power doorlocks. The addition of a power
doorlock interface to a vehicle with non-power locks will not allow the security system to
operate the doorlocks. However, power doorlocks may be added to the vehicle in the form
of adding a model DS-2 Electric Door Lock Actuator to each of the doors. This will allow
the security system only to operate the doorlocks.
The vast majority of power doorlocks are found as three system types: 3 wire negative
pulse, 3 wire positive pulse and 5 wire reversal, rest at ground. Other power doorlock systems
which may be encountered are the vacuum pump types found in most Mercedes vehicles and
the single wire, dual-voltage which has appeared in some late model vehicles. The best way
