Claims

[Scope of utility model registration request]

When the address data of the transmission signal sent by time division multiplex transmission from the receiver via the transmission path matches its own unique address, it receives control data based on the mode data or returns monitoring data to the receiver side. a transmission signal processing section that generates a control signal to control an external load such as smoke prevention equipment based on the control data taken in by the transmission signal processing section, and a control output section that generates a control signal to control an external load such as smoke prevention equipment based on the control data taken in by the transmission signal processing section; In a repeater of a disaster prevention monitoring device, which is equipped with a monitoring input section that takes in the monitoring input of the controller and outputs it as monitoring data to the transmission signal processing section, the external load operation monitoring input and its own control check input are connected to the control output section. A data selector section that outputs a control check input during the generation period of the control output timing pulse, which is switched by a control output timing pulse when a control signal is output, and an output from the data selector section that latches when a plurality of predetermined clocks are input. A sampling input latch circuit, a high-speed clock whose clock generation period is set to be able to generate the predetermined plurality of clocks or more within the transmission period of the transmission signal for one channel, and a high-speed clock whose clock generation period is set to be able to generate the above-mentioned plurality of clocks or more within the transmission period of the transmission signal for one channel; The disaster prevention device is characterized by comprising switching means for switching between a low-speed clock set larger than the generation cycle and a high-speed clock by the control output timing pulse and inputting the clock to the sampling input latch circuit during the generation period of the control output. Monitoring equipment repeater.
