Patent number: 5430433Abstract: A radio analog sensor for transmitting analog signals of a temperature or smoke density to a remote place by radio is used as each of sub devices 12-1 to 12-n. When a change of the analog detection signals of a temperature, a smoke density or the like, which is detected by the analog sensor 10 connected to each of the sub devices, is greater than a predetermined value, the analog signals which have been so far stored in a memory are collectively transmitted to the receiver side by radio. Periodic information is also sent from each of the sub devices 12-1 to 12-n once every two hours so as to supervise the state of the sensors. This permits reliable transmission of necessary data to a remote place without decreasing the life of the battery.Type: GrantFiled: October 27, 1992Date of Patent: July 4, 1995Assignee: Hochiki Kabushiki KaishaInventor: Hiroshi Shima
