SECURITY/CENTRAL LOCKING – CIRCUIT OPERATION

Lazy Locking

Lazy locking can be carried out when either locking or superlocking, or when the vehicle is already in a locked state, by either holding the key turned to the lock position or by holding the remote handset lock button pressed for more than one second. This will cause all the open windows to start closing simultaneously. Closure of the windows will be followed by closure of the sunroof. Dependent upon market requirements, lazy locking will either operate in one-shot mode, or in dead man’s handle mode. In one-shot mode, the windows and sunroof will
continue to close even after the key has been released from the lock position, or the lock button on the remote handset has been released. In dead man’s handle mode, closure of the
windows and sunroof will only continue for as long as the key is held to the lock position, or the lock button is pressed on the remote handset. In this case, failure of any of the apertures to be fully closed upon release of the key/button will result in a mislock.

Mislock

A mislock condition is indicated by either two short “beeps” from the alarm sounder, or by three short flashes of the courtesy lights, depending on the market legislation.

Partial Arming Of The Perimetric Alarm

If the perimetric alarm is armed with one (or more) of the doors, or the tailgate, or the bonnet open, then the remaining panels are all protected by the alarm. If any of the open panels are subsequently closed, then they too will be protected by the alarm.

Security LED

The security LED has two functions: Firstly for the initial ten seconds after a lock
request, it provides visual confirmation of the lock status. Secondly, after this confirmation period, it acts as
a deterrent to any theft attempt, (flashing at a slower rate).

Volumetric Protection

Volumetric protection, (protection of the vehicle’s interior), is provided by an Ultrasonic Sensor and an Ultrasonic detector .

If the vehicle has been successfully superlocked with the key, then provided all the windows are closed, a single press on the remote transmitter lock button will activate the ultrasonics. There is a 5 second settling period before movement can be detected.
