The security relay is a simple accessory which we recommend using 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 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.
