Abnormal temperature alarms associated with fires in multiple locations can be detected by fire detection lines / New product of fire detection line alarm.

1. Connect the alarm device to the fire detection line using a connector. However, the alarm device is composed of an electronic buzzer, a pin switch, and a battery (DC 4.5V). The pin switch is equipped with a strap and serves as the test switch for the electronic buzzer.
2. By inserting the fire detection line from indoors into the ceiling space or under the floor, the fire memory sensor detects abnormal temperatures associated with a fire in each location, such as "the ceiling space and indoors" or "under the floor and indoors," and alerts through the alarm device installed indoors. The fire detection line is inserted in various places, such as gaps between walls and furniture, and inside home appliances, to detect abnormal temperatures associated with a fire and alert through the alarm device.
3. For example, when abnormal temperatures associated with a fire occur in the ceiling space, under the floor, or indoors, the fire detection line detects the abnormal temperature and alerts through the alarm device installed indoors.
[Note] 1. The fire detection line is a product that combines multiple shape memory alloys at equal intervals on an extended wire. (Setting temperature 80°C) It is a product that attaches multiple fire memory sensors (shape memory alloys) to the wire.
[Note] 2. When the surrounding temperature reaches (80°C), the wire softens, and the shape memory alloy binds the wire (restores), short-circuiting the two wires to sense the temperature and generate a signal. However, the softening temperature of the wire and the restoration temperature of the shape memory alloy are the same temperature (80°C).
