The FK504 detects a sudden change in the vehicle's 12v electrical system, such as that caused by a door opening, turning on the interior light, starting the car or by wire tampering. Unless disabled by using a secret switch within 10 seconds of entry, the FK504 will initiate an alarm signal through the car's horn circuit or other warning device.
