2N 9151198SET intercom system accessory Security relay

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.

The additional and tamper switch activates an alarm if detects intrusion into the intercom’s frame. Prepare also more advanced scenarios in the Automation section. The intercom could be set, for example, to play a pre-recorded message, contact a security agency or photograph the vandal.

The components of the bundle are also available separately.
