3-Circuit Breaking, Anti-Theft Alarm

3-circuit breaking
Integral with the anti-theft alarm's electronic control module is a "3-circuit breaking" function which takes over control of the following functions when the alarm is armed. This prevents the engine from being started when the alarm is set off, as follows:
- The starter relay (ignition "ST" +50) receives no operating current because the anti-theft alarm control module (pin 8) breaks the circuit if an attempt is made to start the car.
- The fuel pump relay receives no operating current because the anti-theft alarm's control module (pin 9) breaks the circuit. (The engine receives no fuel - the car cannot be push-started, either.)
- The engine management system does not receive a +15 supply because the alarm control module (pin 22) breaks the circuit.

Connection
The "3-circuit breaking" function is connected when the rest of the alarm is armed.


Disconnection
The "3-circuit breaking" function is disconnected when the rest of the alarm is disarmed.

Self-arming, 3-circuit breaking
The 3-circuit breaking function can be independently programmed for self-arming, that is to say automatic arming with the use of the remote control or car key.


Self-arming, anti-theft alarm
The entire anti-theft alarm system can also be programmed for self-arming. In this case, 3-circuit breaking is automatically included when the alarm is armed.
