Abstract

Detection and alarm system by radiotransmision. Various sensors and push buttons (1, 2) can transmit radio frequency signals to a central receptor unit (3), which in some time can activate alarm or alumnum devices (4) connected to it by cable or radio. Each sensor consists of a detector, an automatic switch and a coded signal transmitter. The receiving central (3) is formed by a receiver, an amplifier, a filter, and a decoder that acts on the signal received and remove from it an identification signal that commands an alarm block.
