Automatic fire detection equipment is mandatorily installed in multi-family homes (apartments) to detect the occurrence of a fire and communicate the fire situation to enable rapid evacuation.However, in small dense residential areas such as multi-family houses, multi-family houses, townhouses, one-room villas, and urban living houses such as single-family houses, the alarm sounds only within each household, so neighboring (adjacent) households can quickly recognize the fire situation and evacuate. There are not enough means to do so.By introducing an extension to an existing fire alarm system, fire alarms can be quickly disseminated between neighboring households.To achieve this, the following methods can be used to quickly disseminate fire alarms:Alarm device connection using a control server: Connect alarm devices between adjacent households so that in the event of a fire, an alarm can be sounded in neighboring houses.This allows you to recognize a fire outbreak and begin evacuation procedures immediately.Additionally, a motion sensor is attached to the detector, so it is possible to monitor whether there are people inside the house in the event of a fire.This information can help save lives in the event of a fire.
