Setting Off the Alarm






When the alarm is armed, it is set off if alarm data is received by the control module on the following connections:
- The door switch is grounded (pin 4).
- The hood switch is grounded (pin 16)
- The luggage compartment switch is grounded (pin 3).
- Signal from the glass breakage sensor (pin 7)
- Signal from the sensor disconnecting button (pin 7)
- Connecting or bypassing the ignition, "ON" position (+15) on the ignition switch (pin 10).

When the alarm is set oft, the horn sounds for 30 seconds and the direction indicators flash for 5 minutes.

Starter and fuel pump relays as well as engine control system +15 are immobilized for 30 minutes. Each attempt to start the car extends the immobilization time by 30 minutes. If the ignition is on, these will be continuously Immobilized as long as the alarm is armed.

To switch off an alarm that has been set oft, it is disarmed in the normal way with the remote control or the car key.


Important : This type of alarm tripping is standard (at delivery). Flash and sound times can be reprogrammed as required by the local market.
