- A door that opens inward with a handle or knob*.
- A suitable locking cylinder that protrudes 8 to 15 mm on the inside of the door.**
- A smooth-running lock or bolt.
- A suitable mobile device (support from iOS 8.3, Android 4.4, and Windows 8.1).
Tip: We recommend locking cylinders with an emergency and danger function (also known as a priority function). This means that the lock can be unlocked, locked, or opened from the outside with a key if necessary.
*If the door opens outward, the distance between the locking cylinder and the door frame must be greater than 30 mm.
