LEHMANN electronic lock MA420 with keypad black
System features:
single-use code locking (FREE mode)
Locking and unlocking are performed using a user-defined code consisting of 3–10 digits. After unlocking, the lock is automatically reset and ready for the next user, who can set a new code of their choice. In this mode, automatic unlocking at a specified time can also be configured, for example to release unoccupied locked lockers.
Fixed code locking (FIX mode)
The same user code, consisting of 3–10 digits, is used for both locking and unlocking.
FIX/FREE mode switching
The operating mode can be changed at any time to suit operational requirements.
Master code
The lock includes a Master Code, which can be used to open the lock if the user code is forgotten. The Master Code can be changed.
A low-battery warning is indicated by an LED on the keypad.
