Appendix C – Central Locking System Configuration
When installed in a vehicle with central locking, the Helios unit can be
configured in two ways:
1. Helios can control the central locking system to lock/unlock the vehicle
doors when it changes the logic state from Armed to Disarmed and vice versa.
The control can be performed manually, by sending a command, or
automatically, when Helios enters Armed/Disarmed logic state according to the
Logic settings, or specified event settings.
2. The central locking system can control the Helios logic state, changing the
Helios logic state from Armed to Disarmed and vice versa each time the vehicle
doors are locked/unlocked.
Installation
Before making any changes to the vehicle wiring, verify which type of locking
system is in use. If you can identify the location of the locking engine and gain
access to its terminals, you may be able to make a direct connection without
adding external relays.
(–) (–) Locking
In this locking method, a negative pulse activates the locking mechanism and
the next negative pulse activates the unlocking mechanism. This is called (–) (–
). It is also possible to use (+) (+).
For vehicles with (–) (–) locking systems, you can wire the unit without adding
any external relays, as follows:
Connect Door Lock GRAY/ORANGE cable on 24-pin Helios wire harness (Pin
13) to the vehicle central locking input responsible for the Lock command.
Connect Door Unlock GRAY cable on 24-pin Helios wire harness (Pin 2) to the
vehicle central locking input responsible for the Unlock command.
