E-Variator B - Electronically Controlled Key Lock

Electronically controlled, changeable lock with dead bolt for safes CEN III-V.
Approx. 10 million theoretical variations.
Standard footprint.

Depending on the control conception different release functions (e.g. time delay, dual mode, remote release) or an electronic blocking function can be realised. A start signal for the external control system is activated by the key opening. The start signal as well as the bolt monitoring is offered as output.

Change can be initiated from the front utilising a change activator or via a slide unit at the back of the lock.
