Abstract (en)
[origin: EP3333817A1] An object of the present invention is to reduce power consumption. An automatic fire alarm system slave device (1) includes a receiver (15) and a controller (17). The receiver (15) is electrically connected to a pair of cables (31, 32) and receives a signal transmitted from a master device (2) by varying a voltage (VI) applied between the pair of cables (31, 32). The controller (17) switches a state of the receiver (15) to either a reception enabled state in which the receiver (15) is operating or a reception disabled state in which the receiver (15) stops operating. The controller (17) is configured to switch the state of the receiver (15) to either the reception enabled state or the reception disabled state by intermittently applying a power supply signal (PS1) to the receiver (15). The power supply signal (PS1) supplies power to operate the receiver (15).
