摘要

A remote device for a vehicle theft alarm comprised a transmitter 6 for activating and deactivating the alarm and a receiver 5 for confirming activation and deactivation of the alarm and warning when an intrusion has occurred. The alarm transmitter 3 on the vehicle is part of a circuit which activates the vehicles indicators. The remote device is charged at a point inside the vehicle; if the driver forgets to take the remote with him when leaving the vehicle a warning signal is given.
