New safety alarm for use in construction site safety equipment.

■Overview of the Safety Alarm Device
1. This is a fire alarm device with security features that connects a fire memory sensor (switching function) to a general security alarm circuit composed of an alarm device, a pin switch, and a battery (DC 4.5V).
2. The pin switch is equipped with a strap and serves as a test switch for the alarm device, as well as an emergency switch.
4. In construction sites, the safety alarm device should be carried around (such as in work clothes or work bags).
(1) For example, in emergencies due to health issues like heatstroke, or accidents caused by misoperation or malfunction of construction machinery, the pin of the safety alarm device carried around can be pulled out to sound the electronic buzzer for emergency alert.
(2) For example, if a fire occurs after work, the fire memory sensor of the safety alarm device installed at the work site will detect the fire and sound the electronic buzzer to alert about the fire.
5. The device should be installed in areas at construction sites where there is a risk of fire (such as break rooms, work areas, material storage areas, temporary offices, temporary warehouses, and waste disposal sites).
[Reference 1]: In the event of a fire, even if the case material of the safety alarm device deforms (melts), it will emit an alarm sound for about one minute. Depending on the fire situation, it can typically emit an alarm sound for about 20 minutes from the onset of the fire.
