Hello.
It is possible. You need to use Immobilizer scenario.
1. Set ignition source to DIN1.
2. Connect buzzer to DOUT interface (DOUT1 for example).
3. Input authorised iButton IDs in a configurator.
4. Configure scenario.
In this case everything should work like this.
Driver turns on Ignition and configured DOUT turns on, if buzzer is connected then a buzzer turns on, if driver uses authorized iButton configured DOUT turns off, in case of a buzzer it would turn off. After ignition turns off and 180 seconds (3 minutes) passes authorization is needed again to turn off a buzzer.
Best Regards.
