B&B Locks – Security Locks – The B1 Lock

The B1 is a high-quality electromechanical security lock. The B1 is the follow-up to the M4, an electronic lock that we have already supplied to many Swiss prisons. Do you currently have an M4 type lock in your door and would like to avoid major modifications? Then the B1 lock is the ideal solution for you.

The advantages of the B1 lock include the following:
  • This security lock is extremely robust and offers fast locking and unlocking.
  • The B1 lock is specially developed for doors that are usually closed.
  • Thanks to the potential-free signalling on the security lock itself, you do not need to provide a separate printed circuit.
  • The B1 lock is also available with two cylinders and an anti hostage-taking function.
  • You can access using a push button, card reader, code keyboard, fingerprint, etc. The security lock automatically locks as soon as the door closes. But what about a power failure? When electrical power fails, you simply unlock it with a key.
  • B&B Locks produces this type of lock on request.
