Car Starting Alarm Kit


Connect this to your car battery and install the kill switch in a hidden place. When someone starts your car, the circuit will detect a drop in voltage from the car’s battery, used by the starter, and the circuit will wait approximately ten seconds, then it will trigger your 12v siren!


This kit runs on your cars 12vDC battery and uses it as the sensor.
To disable the siren, you flip a switch, which kills the power to the circuit.

The car starting alarm circuit which can be connected to a horn or siren delays the in-out time at 10 seconds and sets time to re-start in a minute
It can be applied to a motorcycle or a car with 12 volt battery
