用監視制御装置。 A unique address is set for each of a plurality of terminal devices connected in parallel to a transmission line extending from the central device, and each terminal device responds to a sequential call containing the unique address from the central device by the transmission section. In a disaster prevention monitoring and control device that sends and receives information or controls disaster prevention equipment when it detects an address that matches its own address, the terminal device is triggered based on the address matching pulse output from the transmission section and outputs an output pulse. It is characterized by comprising a mono multivibrator whose width is set to be longer than the polling period and which is capable of retrigger operation, and an AND circuit that takes the AND of the output signal of the mono multivibrator and the control signal from the transmission section. Disaster prevention monitoring and control equipment.
