ステム。 In a self-fire alarm system that supplies power to each repeater from a receiver, calls each repeater using a multiplex transmission signal, and sends alarm information from a sensor connected to a line connected to the repeater back to the receiver. ,
When a fire alarm is received for a certain number of lines or more, a switch means is installed for each line connected to each repeater to cut off power to the line where the alarm has been issued using a control signal sent from the receiver. Features self-fire alarm system.
