Feature #3: Automatic Last Door Arming. (Factory Setting: ON)
Feature Turned On: The security system will arm itself automatically when the
vehicle's last door is closed. At the moment the last door is closed the siren will chirp,
the exterior lights will flash once, and the Status LED will flash fast. Thirty seconds
later the siren will chirp once again, the lights will flash, and the Status LED will flash
slow, indicating that the security system is fully armed. If feature #4 is
selected, the doors will also lock at this time. If the negative instant trigger is grounded
at any time during the thirty second countdown (Example: opening the trunk), the
Automatic Last Door Arming feature will be interrupted. When the negative instant
trigger becomes ungrounded, the security system will become fully armed thirty
seconds later. Note: All of the doors and the trunk must have the proper connection
of the control module's wiring. This feature allows unhurried passenger exit and trunk
access, as the Last Door Arming process does not start until the last door or trunk is
closed, and opening any door or the trunk will interrupt the process. You can still, of
course, actively arm the security system with the transmitter at any time.
Feature #4 Doors Will Also Lock With Last Door Arming: (Factory Setting: ON)
Feature Turned On: When the security system passively arms from the Last Door
Arming feature, the doors will also lock if an optional doorlock interface was added.
This will occur when the system becomes fully armed 30 seconds after closing the last
door.
