Corresponding to a monitoring and alerting device having
In a self-fire alarm system including a self-fire alarm receiver, a fire sensor is installed based on a predetermined fire sensor installation plan, and a unique address of the fire sensor is set.
The self-fire alarm receiver stores a physical address, which is a unique address of the fire sensor to be connected, and a district management number in the storage means as a connection terminal address table based on the fire sensor installation plan. . Then, a physical address table having address data which can be set by a plurality of fire sensors is provided in the storage means, and the fire sensors are accessed sequentially and sequentially from the fire sensors based on the physical address table. After comparing the unique address data of the reply information with the connection terminal address table, a fire occurrence detection process is performed to display a district management number and perform a fire occurrence notification process.

[0003] The above-mentioned self-fire alarm system receives the self-fire alarm when there is no reply data when the self-fire alarm receiver accesses the address of the unique fire sensor due to a failure of the fire sensor, for example. An indication of the occurrence of an abnormal condition for notifying "sensor not connected" is displayed on a display means provided in the machine to prevent a fire from being detected or a delay in taking action. Also, if the unique address is incorrectly set at the time of installation of the fire detector and it is not registered in the connection terminal address table based on the detector installation plan due to forgetting to register, etc. If there is a reply from the fire detector that has been sent, similarly, an indication of the occurrence of an abnormal condition that notifies "excess connection of the detector" is displayed on the display means, and the connection terminal is found by finding the fire detector. The aim is to prevent delays in fire response due to forgetting to register in the address table.
