AUTO SWITCH-ON
The auto switch-on operation allows the alarm system to change from rest to surveillance automatically and on a timed basis.
There are two methods of auto switch-on.
FROM KEY-OFF
- KEY-OFF is detected
- The auto switch-on counter starts counting
- If a transition from open to closed on any of the doors or the bonnet or boot is detected, the counter restarts from zero.
- The counter reaches the 'AUTO SWITCH-ON TIME'
- The BC checks whether an enabled key is inserted
- If an enabled key is inserted, auto switch-on is carried out
- If an enabled key is not present, auto switch-on is carried out
PASSIVE method
- KEY-OFF is detected
- The auto switch-on counter starts counting
- If a transition from open to closed on the driver's door, or any of the doors or the bonnet or boot is detected, the counter restarts from zero
- if the counter reaches the value of 2 minutes without any transition from open to closed being made, auto switch-on is cancelled.
- the counter reaches the 'AUTO SWITCH-ON TIME'
- the BC checks whether an enabled key is inserted
- if an enabled key is inserted, auto switch-on is carried out
- if an enabled key is not present, aut switch-on is carried out
The auto switch-on methods are enabled depending on the operating modes (see country map table 'PASSIVE AUTO SWITCH-ON ENABLEMENT' and 'KEY-OFF AUTO SWITCH-ON ENABLEMENT').
Surveillance from auto switch-on is complete for all entry points; the operating modes make it possible to:
- activate/deactivate volumetric surveillance
- activate/deactive the anti-tilt module
In auto switch-on, the system test is carried out as in ordinary switch-on.
Door locking is not activated during auto switch-on.
The visual/acoustic indications are enabled by the operating modes
The definition of the driver's door in the different versions (right-hand drive and left-hand drive) is specified during end-of-line programming by the manufacturer.
