Title: Communication equipment for security
Inventor: ODA HAJIME
IPC: G08B25/10
Filed: 2000-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a communication equipment for security capable of realizing power saving and identifying plural slave sets by simple constitution. SOLUTION: When a sensor in a slave set BRk outputs a detection signal, a reception circuit in the slave set operates to start the reception of a timing signal transmitted from a master set MS. Then, when the timing signal is received, the detection signal is transmitted by radio with timings late by a delay time which is set previously to each slave set, behind the receiving timing. When the set MS receives this detection signal, the set MS identifies the slave set transmitting the detection signal received based no a time difference between the receiving timing and the occurrence timing of the timing signal.
