3A63 - ATLAS® Electronic Pass Lock



To provide secure locking of swinging pass doors controlled by Atlas® LCMS software or conventional key control. Atlas® LCMS software provides a range of operating functionality which can be configured to suit each site.


The 3A63 is a mortice lock of robust construction based on the Chubb Locks Custodial Services standard large mortice footprint. The main bolt extends by 25mm and is operated turning the handle to both lock and unlock. The lock is designed to accept inputs from tokens and can be programmed to enable a range of time / date driven access permissions. Locks can also be controlled remotely from a control room environment.

  • Electronic Mode - Deadlocking is achieved by closing the door and turning the handle to fully extend the bolt. Unlocking is achieved by inserting an electronic token (key) into the lock which, after authentication, an input signal is provided to lift the blocking device and withdrawing the bolt via the handle. The lock can also be configured to provide features such as auto-relock, door insecure time out etc. Additionally remote operation can be achieved via Atlas® Client / Mimic PC.
  • Manual Mode - Locking/unlocking achieved using conventional (mechanical key). Bolt withdrawal by handle. Key operates from both sides of the door
  • Manual Override - In the event of power or communication failure an override key is used to lift the electric locking unit. Both keys are supplied to a different combination and are clearly identified.
