2N security relay, protects against opening the lock with a 12 V battery

The security relay is a simple accessory 2N recommends using with every intercom and reader. It significantly improves the security of the installation at minimal extra cost: it prevents doors from being opened with a 12 V battery – a technique that lets burglars open low-power locks if they reach the cables connecting the intercom/reader to the lock.

Key features

• Protection against 12 V battery opening
• For all 2N intercoms and readers
• Installed between lock and intercom
