| 3 circuit breaking |
There is a 3 circuit breaking function incorporated in the alarm control module which takes over control of the functions listed below 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 voltage as +50 is fed to the
alarm control module (pin 20) which breaks operating voltage on pin 8 if an attempt is made to
start the car.
|
|
| • |
The fuel pump relay
receives no operating
voltage as the alarm control module receives a fuel pump signal on pin 21 from the engine
control system. The alarm control module then breaks operating voltage on pin 9 to the fuel
pump relay. The engine receives no fuel. The car cannot be push started either.
|
|
| • |
Engine control system
does not receive +15
as the alarm control module (pin 22) breaks the voltage.
|
|
| Connection |
3 circuit breaking is connected when the rest of the alarm is armed.
| Disconnection |
3 Circuit breaking is disconnected when the rest of the alarm is disarmed.
| Self-arming, 3 circuit breaking |
3 circuit breaking can be independently programmed for self-activation, i.e. automatic arming without the use of the remote control.
| Self-arming, theft alarm |
The entire theft alarm can also be programmed for self-arming. In this case, 3 circuit breaking is automatically included when the alarm is armed.
Also see the section on "Programming" for further information.
