Abstract: A fire receiver includes a light emitting device; a supervisory control apparatus for performing supervisory control based on information from a plurality of terminal devices such as fire detectors, and for displaying the information by causing the light emitting device to emit light; and a brightness changing device for changing the brightness of the light emitting device in response to the brightness of the surrounding environment.

Abstract: A fire alarm system provided with a fire receiver (1) to which a plurality of fire sensors and controlled apparatuses are connected. The fire receiver (1) comprises a LAN interface (11) for connecting with other fire receivers. When a fire sensor issues an alarm, the fire receiver transmits the fire information over the LAN together with a group number set in advance, and displays (12) only the fire information of the same group number when the fire receiver receives fire information transmitted from the other fire receivers via the LAN. Thus, even is a plurality of fire receivers are used in a large building divided into ridge sections, fire information can be shared without causing disorder.
