The firefighting system that prevents disasters caused by fire includes a fire detector that detects the occurrence of a fire, a fire receiver that issues an alarm when a fire detection signal is received from the fire detector, a guide light that guides an evacuation route in case of a fire, and a toxic gas caused by a fire. It is composed of various facilities such as supply and exhaust dampers that supply outside air to the evacuees, and fire shutters that block the spread of flames and toxic gases caused by fire.

There are various types of fire detectors, such as heat detectors that detect heat caused by a fire, smoke detectors that detect smoke, and flame detectors that detect flames.

Fire detectors are installed in various parts of the building to detect the occurrence of a fire. Most fire detectors do not have their own location information, so even if a fire detector detects a fire, it can accurately locate the fire in a building with a complex structure. There is a problem that is difficult to find.

In addition, even if the fire detector malfunctions, the fire receiver issues an alarm. As the malfunction is repeated several times, the alarm sound is loud and it is cumbersome to clean up the discharged fire extinguishing water, so the fire receiver is operated so that it does not operate. There have been unfortunate fire accidents where evacuation was not done in time and the fire was not normally extinguished.
