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.
