Installation Points to Remember
o When working on a vehicle always leave a
window open.
o Never leave the keys in the car. Leave them
on a workbench with a window rolled down.
o If possible, remove the courtesy light fuse to
prevent battery drain.
o Inspect the vehicle for any body damage or
electrical problems.
o Make sure that all the switches and controls
operate properly.
o Verify that the vehicle starts and idles
properly.
o Never install a control unit where it could
interfere with normal operation or obstruct
service technicians.
o Do not disconnect the battery on vehicles
equipped with air bags and anti-theft radios.
o Always use a grommet when running wires
into the engine compartment.
o Never run wires through bare or sharp metal.
o Always solder and tape all connections.
o Never ground the control unit to the steering
column of the vehicle.
o When you probe /test the wires of a harness,
make sure you check the plug-in connector.
o The wires for the air bags are not always
identified on the harness (split loom or a
yellow tape). However they are always
identified on the connector.
o Keep the transceiver away from other types of
antennas (GPS/Onstar).
o Make sure all security equipment is installed:
The Valet switch, the hood pin and the
warning label.
Programmable Features
The unit was designed with flexibility and OEM integration in mind. The system gives installers the output
flexibility that every good installer is looking for; this unit can be customized and used for almost every possible
application.
With the integration of timed latched and ON / OFF outputs, this unit can single-handedly control virtually any
electrical system in the car.
The programmable features are as follows:
1. Siren or OEM Horn Output
• The system can be programmed either to control the OEM horn or to command an external high-power
siren.
2. Siren / Horn Chirp Timing
• This feature allows you to configure the duration of the horn/siren chirps generated by the system. The
horn/siren chirp duration can be set to any length between 10 ms and 250 ms.
3. Ignition-Controlled Door Locks
• OFF by default. This feature will LOCK all the Doors of the vehicle while the Ignition Key is in the IGNITION
ON (RUN) position and only when all the doors are closed (there is no recurrence of this action). The unit
will UNLOCK all Doors when the Ignition Key is turned back to the OFF position.
• If Ignition Lock Only is selected, the system will only LOCK all Doors while the Ignition Key is in the
IGNITION ON (RUN) position and only when all the doors are closed (there is no recurrence of this action).
• If option Ignition Unlock Only is selected, the system will UNLOCK all Doors when the key is turned to
the OFF position (provided that the Ignition key was in the IGNITION ON (RUN) position).
4. Passive or Active Arming
• (Passive with a 1-min. time out by default.) The alarm system on this unit can be set to active mode (in
which it will not arm itself automatically) or to passive mode (arms itself automatically) with a 1-minute
timeout.
5. Door Lock Pulse Duration
• (¾-sec. lock and ¾-sec. unlock pulses by default.) This system can be programmed to give either 3.5-
sec. lock /unlock pulses (this is used to control vacuum door-lock system, for instance on Mercedes) or a
single ¾ -sec. lock pulse with a double ¼-sec. unlock pulse (this is used for double-pulse disarm/unlock
systems, as in the Maxima, Pathfinder, and Volkswagen…)
6. Relock
• If you unlock the doors with the remote transmitter, but do not open any door or trunk within 60 seconds,
the doors will automatically relock.
