Abstract
PURPOSE:To carefully supervise fire information by using a supervising terminal equipment to return the fire information by means of time division multiple transmission, and by checking a sensing circuit connected with a contact type sensor. CONSTITUTION:By using a supervising terminal equipment 2 to return the fire information consisting of analog data by means of the time division multiple transmission, a sensing circuit 6 connected with a contact type sensor 7 is checked. Consequently, only by contacting the sensing circuit 6 to a base 4 of the nearest supervising terminal equipment 2, wiring can be facilitated even at the time of the wiring of many sensing circuits 6, and the costs of the wiring are made lower. Thus, the sensing circuits 6 can be made as many as possible, the sensors 7 connected to the sensing circuits 6 are made as few as possible, and the fire information can be carefully supervised. Further, compared with the case to provide many terminal equipments 2 at respect supervising places, the system costs can be lowered.
