The module detects any unauthorised opening of the intercom. By using this, you significantly improve the security of the whole installation. You connect the tamper switch directly to the security control panel. If any unauthorised tampering occurs, the switch triggers an alarm. For a more comprehensive setup in the Automation section, it is necessary to connect the tamper switch to an I/O module (01257-001) or Wiegand module (01259-001). You install the tamper switch in a special location in the main unit. It does not need a separate slot.
