Redundant Safe Lock

The Duet safe lock combines an electronic safe lock and a mechanical combination lock in one housing. The operator takes advantage of both systems.

The lock has the standard assembly dimensions (66.5 X 41 mm) and can be installed in all 4 positions (RH, LH, VU, VD). Although it is a 4-disc lock, the case is less than 30 mm thick. Because of this, the lock can be installed in almost any safe or security box.

As with a normal electronic lock, the code is entered via the keyboard. But what happens if the electronics are defective? You set the code with the mechanical number disk and the safe opens.
