The Electronic thumbturn cylinder, dummy on one side - 917.37.005 by Hafele represents a refined fusion of quality and functionality. This product is designed for integration into mortice locks, suitable for door thicknesses ranging from 40 mm to 110 mm. Battery-operated, it is not intended for use in corrosive environments such as chlorine, ammonia, or lime water.
As an intelligent thumbturn cylinder, it allows contactless activation using a Dialock key. Users receive acoustic feedback when the key is presented, and the illuminated ring indicates status: green for unlock, red for lock, and no LED for standby. The standard setting engages the thumbturn outside with an authorized Dialock key for 10 seconds before automatically disengaging. Service personnel are notified of programming status and battery change requirements through acoustic error messages.
The Electronic thumbturn cylinder stands out for its high security and ease of use, making it an essential component of modern access control systems.
