These 3 wires allow the alarm to control the
power door lock/unlock systems of most vehicles
without external relays. However, one or two
relays may be required in some cases.
The alarm has a built-in timer which is pre-set
for 0.5 seconds, but which can be programmed
for 3.5 seconds.
Types of door lock/unlock systems At the time
this manual was completed, there were seven
common types of power door lock/unlock
systems in use:
A. Negative relay switching to factory actuators
The factory door lock switch has 3 wires.
One wire always shows ground. The LOCK
WIRE becomes ground when the door is
locked, and sends a pulse to a factory relay
to lock the doors. The UNLOCK WIRE
becomes ground when the door is unlocked,
and sends a pulse to a factory relay to
unlock the doors. Most Japanese cars use
this system. THIS IS THE MOST COMMON
TYPE OF POWER DOOR LOCK SYSTEM.
See fig. 16.
B. Positive relay switching to factory actuators
The factory door lock switch has 3 wires.
One wire always shows +12VDC. The
LOCK WIRE b12VDC when the
door is locked to pulse a factory relay to lock
the doors. The UNLOCK WIRE becomes
+12VDC when the door is unlocked to pulse
a factory relay to unlock the doors. Most
General Motors cars use this system.
