8 or 40 different user codes.
With its reliable operation, this digital keypad lock is ideally suited for actuating electronic access systems (e.g. house doors and a garage doors). The right code, consisting of 4 to 6(8) digits in the correct sequence, must be entered to actuate switching. These 8 or 40 codes can be freely programmed by the user, i.e. entered via the keypad. The keypad is blocked for 60 seconds for three incorrect entries. A buzzer is behind the keypad. The respective codes are retained even in the event of a power failure.
Function:
If the code is entered in the correct sequence, the relay switches on for 1 second and then switches off again. The time 1 second can be reprogrammed via the keypad. Several keypads can be connected in parallel to one code lock. Split system for higher safety.
