Abstract

The antitheft alarm system uses one or several portable radio signal transmitters (10). Each transmitter emits the same predetermined frequency. A radio receiver is placed in the building, room or vehicle to be protected. The radio receiver is tuned to the transmitter frequency. The radio-receiver controls a relay (7) which has a contact (8, 16) in the supply connections coupling an energy source (4) to the alarm system (1). Each of the transmitters is coupled to the ignition keys (12) of the vehicle. The transmitter and receiver each include a pilot quartz oscillator. The transmitters have a very low power output of the order of several hundred miliwatts so that their ange is about several metres. The transmission frequency is chosen from one of the following bands: 27 MHz, 72MHz, 144MHz, 400 MHz.
