Description

Anti theft device

Block diagram

•	BCM : Arming-Disarming data output

•	SIREN : Siren ON when disconnecting the battery, TILT & UIP sensor input

•	OFF switch : Alarm function OFF

•	TILT sensor : Sense the vehicle angle

•	UIP (Ultrasonic Intrusion Protection) sensor : Sense the unauthorised entry

This system is designed to provide protection from unauthorised entry into the vehicle.

This system is operated in three stages :

the first is the "Armed" stage, the second is the "Theft-alarm" stage, and the third is the "Disarmed" stage.

If triggered, the system provides an audible alarm with blinking of the hazard warning lights.

Function

Siren

(1)

Power On-Off

It is necessary to apply voltage to the SIREN to power-on the SIREN.The SIREN saves its status into the internal memory. Before removing the car battery supply or SIREN/Sensors connector. Take care that the system is in DISARM state otherwise it will start to sound using the internal battery.

(2)

Arming-Disarming

The system is armed by BCM specific command on LIN BUS

Conditions to ARM the SIREN

–	System in DISARM STATE

–	IGN OFF The system is disarmed by BCM specific command on LIN BUS

Conditions to ARM the SIREN

–	System in ARM STATE

–	System in ALARM STATE

(3)	Arming Disarming signaling The BCM manages the blinker activation during DISARM to ARM, ARM to DISARM and ALARM to DISARM transition.

(4)

Functional States

–	DISARM STATE In this state the vehicle is not protected

–

Pre ARM/ INHIBITION Time

The Pre ARM or INHIBITION TIME starts when the SIREN receives an ARM command by IPM.

If one or more protections are active during DISARM/ARM transition or during the inhibition time, the SIREN exclude it automatically(except for UIP and TILT sensor). It will be re-included in the protection when it will return in the correct condition A continuous low power sound indicated the exclusion during Pre Arm/INHIBITION time.

The INHIBITION Time duration is 30 sec starting from DISARM to ARM transition.

–	ARM STATE In this state the vehicle is fully protected

–	Partical ARM STATE In this state the vehicle is not fully protected : the UIP and TILT sensor are excluded.

–	ALARM STATE In this state the SIREN is sounding using vehicle battery if present, otherwise its internal.

–	ALARM PAUSE STATE The ALARM PAUSE STATE is a state among two consecutive ALARM STATE

(5)	Stabilization Time The Stabilization Time is the time that the external sensor(UIP and TILT) need to stabilize the function when system are armed. The Stabilization time duration for UIP and TILT sensor is 30 sec starting from DISARM to ARM transition.

(6)

Alarm Causes

The SIREN activates the sound and send to the BCM a LIN BUS command to activate the blinker.

When an alarm condition is detected in ARM STATE

–	PARAMETRIC ………………………………by LIN BUS command

–	IGN Key …………………………………… by LIN BUS command

–	EXTERNAL SENSOR……………………… by INTERNAL LIN command

–	VEHICLE BATTERY TAMPERING……………by POWER SUPPLY Monitoring

–	INTERNAL LIN TAMPERING FUNCTION……by heartbeat Monitoring If the alarm cause is not removed, the ALARM CYCLE is repeated after an ALARM PAUSE. The ALARM CYCLE duration is 27±0.5 sec and ALARM PAUSE is 5±0.5 sec. During the ALARM CYCLE, it is possible to DISARM by BCM specific LIN BUS command.

(7)

Protection

–

PERIMETRIC – IGN KEY

The SIREN protects the vehicle against perimetric opening and ignition key activation attempts.

The BCM sends a specific command to the SIREN if a door/hood/tgate are opened or theignition is turn-on.

If the SIREN is in ARM state or PARTIAL ARM state, it goes to ALRAM state. If the alarm condition remains the SIREN will go again to the ALARM state until the alarm counter is rolled off(total 9 ALARM cycles of 27.5sec and 8 ALARM pause of 5sec, internal memory default)

–

INTERNAL LIN Tampering

If the communication is interrupted during ARM State, the SIREN goes to ALARM state. The the alarm condition remains, the SIREN will goes again to ALARM state until the alarm counter is rolled off(total 9 ALARM cycles of 27.5sec and 8 ALARM pause of 5sec, internal memory default)

–

Vehicle Battery Tampering

If one or both power supply wire(B+ and/or GND) are removed during ARM state or PARTIALARM state,the SIREN goes to ALARM state.

The the alarm condition remains, the SIREN will goes again to ALARM state until the alarm counter is rolled off(total 8 ALARM cycles of 26ec and 7 ALARM pause of 14sec, internal memory default)

–	Internal Battery Connection The SIREN is a self-powered system with internal back-up battery(primary lithium type Typical capacity 1400mAh) The external power supply is always monitored and the behaviour of the system will change According to the following table.

Protections exclusion

Protection	Exclusion modes	RE-inclusion modes
Parametrical (doors, hood, and Tailgate)	Automatic EXCLUSION	RE-INCLUSION AFTER Automatic
	The SIREN is able to exclude only the protection found to be opened, leaving the others enabled	EXCLUSION
	When a door or hood is found to be opened during DISARM to ARM transition or during inhibition time	When the door and hood are closed again
	A continuous low power sound indicate exclusion during inhibition time	When the door and hood are closed again

Protection	Exclusion modes	RE-inclusion modes
UIP and TILT sensor	MANUAL EXCLUSION	RE-INCLUSION AFTER Automatic
	When the UIP and TILT SENSORS exclusion button(OFF SW) is pressed for more than 100ms with the ignition key turn off Exclusion is visually signaled by the activation of the UIP and TILT SENSORS exclusion light	Press again the UIP and TILT SENSORS exclusion button(OFF SW) for more than 100ms with the ignition key turn off. Or Elapsed 5 minutes after activation without receiving any ARM command by LIN BUS Or Inanition Key turned ON The re-inclusion is visually signaled by the de-activation of the UIP and TILT SENSORS exclusion light.
