This combination of code lock and doorbell has already proven itself as a sensible access control for houses, rooms or even sensitive IT areas. An incredible number of different code and user combinations are available. In addition to programming the individual access code, you can also determine which of the two output relays is to be activated by the code entry. If a code has been entered incorrectly 10 times, it is possible to lock the keypad or trigger a silent alarm. In addition, an integrated sabotage contact reliably protects against unauthorised opening of the enclosure.
