When a fire or earthquake occurs, if automatic doors fail to operate, it becomes not just an inconvenience but a serious issue that can threaten lives. In Japan, large-scale natural disasters occur almost every year. If automatic doors that serve as evacuation routes do not open in an emergency, many lives could be put at risk. An important technology to prevent such situations is the "panic open" system. This article will thoroughly explain the panic open function of automatic doors, covering its mechanisms, legal obligations, and the effects of implementation by facility type. [Actual content excerpt] ◎ Specific functions and effects of panic open ◎ Effects of implementing panic open functions by building type *For detailed content of the column, please refer to the related links.

In building safety measures, fire doors (fire-resistant doors) are essential equipment to minimize damage caused by fires. During a fire, they play a crucial role in preventing the spread of smoke and flames, ensuring evacuation time for people, and preventing the fire from spreading throughout the building. To ensure these fire doors function effectively, the selection of appropriate automatic closing devices (releases) is indispensable. In recent years, with the tightening of safety standards in various industrial facilities, there has been an increasing demand for fire protection equipment that functions reliably not only in normal environments but also in special environments. This article focuses on "waterproof releases" used in humid environments and "explosion-proof releases" used in hazardous areas, providing detailed explanations of their functions and applications. [Actual content excerpt] ◎ Features of waterproof and explosion-proof releases and differences from standard releases ◎ Laws and regulations related to fire doors and releases *For more details, you can view the related links.

A fire compartment is a system that separates areas of a building with walls and doors to prevent the spread of fire and smoke throughout the entire structure during a fire. It is mandated by building codes, with strict standards particularly for apartments, office buildings, and commercial facilities. This article will clearly explain the basics of fire compartments, the four types, the equipment used, inspection methods, and how to solve the common issue of "fire doors being inconvenient" with the electromagnetic release "magnet door holder."
