These locks are recommended to be used in interior doors of commercial premises, public buildings, hospitals, educational premises, etc.
You will meet them typically in doors of offices, meeting rooms, technical maintenance rooms, doctor's offices, and in medium traffic fire rated doors.

Tubular frame models with short backset for narrow profiles and doors.
These locks feature a split follower and therefore require a handle-handle fitting (handle or panic bar on the inside and handle on the outside).

These handle controlled locks can be used with both fail locked and unlocked operation. With fail locked operation the lock can be opened by the controlled handle under voltage, not without voltage. With fail unlocked operation the electronic function is the opposite.
Only the outside handle is electrically controlled. The lock can always be opened by the inside handle. Mechanically, an opening by cylinder is always possible.

This handle controlled lock is best suited in medium traffic doors. This lock can be electrically controlled by access control system or by a remote control system such as timer, keypad or push button.
They can be used both in exit and fire rated doors (EN).

These locks cannot be used with door automatics.
