The security relay is a simple accessory and is recommended to be used with each intercom and reader. It significantly improves the security of the installation at minimum additional cost. It 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 intercom security relay between the intercom/reader and lock and pair it with the 2N device. If an attempt is made to open the door, the relay will wait for a verification code from the 2N device. Once the signal arrives, it will actuate the attached lock and open the door. If the signal does not arrive, for example if a burglar attempts to open the door with a 12V battery, the door will remain closed.
Connect the relay to the intercom/reader using the OUT 1 output. The relay has a 12V OUT connector for low-power locks and an electromagnetic relay (RELAY 1) for high-power locks.
