Early detection of fires caused by the use of open flames at construction sites / New product for construction fire alarms.

■Overview of Construction Fire Alarm System
1. This is a construction fire alarm system that combines a fire detection line with an alarm device, specifically a fire detection line (integrated fire sensor) connected to the electronic circuit of the alarm via a connector, resulting in a product with zero standby power.
2. By wiring the fire detection line, a fire alert area is established, completing the installation.
3. It is installed at construction sites after the use of fire.
4. At construction sites, there are many instances of fire-related work across various industries, and after the work is completed, the fire detection line is laid in the areas where fire was used, with the alarm device installed nearby.
5. For example, if a fire occurs in an area where fire is used, the fire detection line laid in that area detects the fire, and the nearby alarm device sounds an alert.
6. In this way, at construction sites, fires caused by the use of fire can be detected early, allowing for initial extinguishing efforts to prevent the fire from escalating.
[Note 1]: The fire detection line is a product that integrates numerous shape memory alloys at equal intervals along an extended wire. Set temperature is 80°C.
[Note 2]: The alarm device consists of an electronic buzzer (maximum 100dB), a pin switch, and a battery (DC4.5V) to form the electronic circuit. A pin switch is also provided for alarm testing.
