"unlock". Since the security system's output polarity must be reversed from negative ground
to 12 volts positive, an optional doorlock interface must be used. Three interfaces are
available - the models DLP-P3, the DLS and the DLS-3 with optional SPDT relays. The
DLS-3 is discussed in detail later.
Model DLP-P3 - Three pin connector with a transistor converter network which changes
the security system's negative pulse doorlock outputs to positive pulses. Allows direct
connection of the security system's outputs directly to a vehicle with positive pulse doorlocks.
Overall length 20". Easier and more efficient than using relays for vehicles that have positive
pulse doorlock systems.

Opening a door while the exterior lights are on after disarming the security system will
cause the exterior lights to turn off 10 seconds after the opening of the door. If the system
has been programmed to lock and unlock the doors with the ignition switch being turned
"on" and "off", an open door bypass of this feature may also be programmed. If a door is
opened while the ignition switch is "on", the trunk release via the transmitter will operate.
CONNECTION: Connect the Green wire to a wire in the vehicle which is common to all
the door pin switches. The correct wire in this type of dome light/door jamb pin switch system
Note: The Driver Pin Switch Often Will Have An
Extra Wire That Goes To The Ignition Key Warn-
ing Chime. This Circuit Will Trigger The Secu-
rity System, But Only From The Driver's
Door, And Is The Incorrect Trigger Wire.
