2. central locking actuated from either of the front doors.

a) locking / unlocking the doors is done through a compressor. Using a digital voltmeter or a voltage pencil identifying the compressor control wire. (Voltage is either (+) 12V or OV as doors are locked or unlocked). This wire is interrupted and makes the connection Command compressor if the car has the facility COMFORT *, command power door locks is done on two wires separated. Is used one of the schemes Command negative or Command positive, and the alarm is set for 11 sec./1 sec. (valid option only for CM 555)
b) locking / unlocking the doors is done through electrically controlled actuators by an existing module. Are identified the two-wire for controlling the module (on the threshold from left / down or the driver’s door) and
connects to one of the schemes Command negative or Command positive. If the car has the facility COMFORT * the alarm is set for 11 sec./1 sec. (valid option only for CM 555).

Some cars (ex. OPEL astra some BMW models) have the option COMFORT * activated by a separated wire of the central locking.
In this case, the wire is connected to the output COMFORT * of the alarm (valid option only for CM 555).
* COMFORT – the windows to be opened or closed by pressing and holding a button on the remote control key fob (automatic lifting of power windows once you lock the the doors).

LED will be lit, and from remotes will command only the electric door locks. To return to the original state will resume the same operations (confirmation will be three flashes).

It is recommended that button installation to be done in a place hidden and protected from the possibility of being accidentally pressed.
