A "fire alarm" is a device that detects heat and smoke and gives a warning with a buzzer. Since the enforcement of the revised Fire Service Act on June 1, 2006, it has become mandatory to install "household fire alarms" in the rooms and stairs of new houses.

The sensing methods are mainly "heat" and "smoke"

Most residential fire alarms detect either "heat" or "smoke". The smoke detection type detects smoke generated in the early stages of a fire, which is effective for detecting a fire earlier, and is generally installed in bedrooms, stairs, and corridors. On the other hand, the heat detection type is suitable for kitchens where smoke is generated during cooking even if there is no fire. It should be noted that the fire is found to be slower than the smoke type because it does not react unless the fire becomes a certain size and the ambient temperature of the sensor rises. There are two types of fire alarm power supplies, one that uses batteries and the other that uses household power supplies. Since the battery type has a battery life of about 10 years, it seems that the entire body is often replaced when the battery runs out. In addition, the type that uses a household power supply requires electrical wiring work and may not operate in the event of a power outage.
