2N Security Relay for Intercom System, Enhances Door Lock Protection, Compatible with IP Verso, Force, Safety, Vario – 9159010 (1 Year Warranty)

Description

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.
