2. Description of the Related Art Conventionally, a so-called R-type (record type) fire alarm system is known as a fire alarm system that monitors a fire by connecting a fire sensor to a signal line drawn from a receiver.

For the R-type fire alarm system, an analog type fire detector with a transmission function with a unique address is connected to the signal line drawn from the receiver, and analog data such as smoke density or temperature is transmitted. When a predetermined caution level is reached, based on the fire interrupt from the fire detector, a search command is issued from the receiver to specify the address of the alarmed fire detector and collect analog data intensively. When it reaches a predetermined fire level, it is determined that there is a fire, the fire representative lamp of the receiver is turned on, an acoustic alarm is output, and the sensor address that detected the fire is displayed on a display or the like.

In this way, knowing the address of the fire detector that detected the fire enables appropriate evacuation guidance and fire extinguishing activities, and is an indispensable function for fire monitoring of large-scale facilities in particular.

In addition, control terminal devices such as fire doors and fire dampers are connected to the signal line drawn from the receiver of the R-type fire alarm system via a repeater equipped with a transmission function. In response to the control signal, the fire door is released and closed, and the fire damper is opened to exhaust smoke.

In addition, a disaster prevention display device is connected to the receiver of the fire alarm equipment. At the position of the fire detector that detected the fire, for example, an alarm symbol that indicates the location of the fire flashes red, and by confirming the location of the fire, it is possible to provide quick and safe evacuation guidance and support through firefighting activities.
