Abstract
An object of the present invention is to provide a fire alarm system which is adaptable to form a large-size fire alarm system and is capable of causing a receiving portion to quickly detect fire information from a terminal unit, or the like, if the terminal unit has been operated. In a fire alarm system in which terminal units, such as fire detectors, are connected to the receiving portion, an address is given to the terminal unit to allow detection of terminal units that have a status change, wherein system polling or the like for a specific terminal unit, such as a transmitter, among the terminal units is performed prior to performing system polling of other terminal units.
