Thanks to the installation of a tamper switch, security relay and I/O module, you can ensure that nobody can forcibly enter the building without the owner knowing.
The tamper switch detects the forcible opening of the intercom and any attempt by thieves to get at the wires and cables. If the frame is loosened even slightly, the tamper switch trips and activates an alarm.
2N IP intercoms are able to directly provide power to low energy locks (up to 12V). This is why it is necessary to ensure that if an intruder gets to the power supply wires for the lock, they will not be able to open the door. This is where the security reply comes in.
