I want to be prepared for emergencies! Reliable emergency opening device function.
The Keylex 4000 series has a setting for "Emergency Opening Device." The "Emergency Opening Device" allows the door to be opened in an emergency by pulling up the green cover at the bottom of the Keylex body and sliding the release lever. This mechanism enables unlocking without entering a passcode or using a key. Even after breaking the cover to operate it, you can reuse the device by simply purchasing a new cover component! In terms of usage cases, both outdoor and indoor versions typically feature a dual-button type, with the emergency opening device often installed on one side. Normally, it operates with a passcode, allowing exit in emergencies or entry from the outside. Therefore, it is implemented in evacuation routes and emergency exits in facilities such as nursing homes, schools, hotels, and train stations. It can also be installed in areas where fire department guidance is required! For the dual-button type, it is compatible with keyed options and integration with other manufacturers' cylinders (MIWA/GOAL/HORI cylinders). This feature contributes to reducing damage during disasters! *Please note that the door can be opened from the emergency opening device side without entering a passcode, so handle with care.
