Increase the security of your doors to the maximum. A useful bundle containing a security relay and additional and tamper switch. The security relay is a simple accessory which prevents doors from being opened with a 12V battery – a technique which allows burglars to open low-power locks if they reach the cables connecting the intercom/reader to the lock. Install the relay between the intercom/reader and the lock it controls. Then pair the security relay with the 2N device. Once set up, the lock will only open if the relay identifies the specific signal sent from the intercom/reader.
