Are the measures in place during an earthquake sufficient? "Automatic Unlocking Box for Earthquakes"

Detects earthquake tremors and allows for quick retrieval of the key even in the absence of the keeper! It detects tremors equivalent to a seismic intensity of 5 weak to 6 weak and automatically unlocks the handle.

The automatic unlocking box during an earthquake allows for quick access to keys for evacuation entrances or disaster prevention storage, even when the key holder is absent at the time of the earthquake. The seismic sensor detects tremors equivalent to seismic intensity levels of 5- to 6-weak and automatically unlocks the handle. Additionally, it can automatically lock the handle after a set time. 【Features】 - Earthquake detection is based on a composite acceleration value from the X, Y, and Z axes. - Time settings for automatic locking after unlocking: approximately 10 seconds, 12 hours, 24 hours, or infinite (lockable by pressing the reset switch). - Earthquake detection levels: four settings available within the range of seismic intensity levels 5- to 6-weak. *For more details, please download the PDF or feel free to contact us.
