Secure relay from Virdi

The Secure Relay from Virdi Distribution SA is used to enhance the level of protection for an access control installation. On a typical access control installation the biometric or RFID terminal has the lock trigger relay onboard, which exposes the installation to intrusion by tampering and manually triggering the relay, thereby causing the door to open. “This might not be a problem on an interior door, but it certainly poses a risk on an exterior door,” said Jonathan Kahn, MD of Virdi Distribution SA.

The Secure Relay is installed on the secure side of the door and the terminal connects to the Secure Relay via the terminal’s Wiegand output, thereby unlocking the door by transmitting a data stream to the Secure Relay. In the event that the terminal is tampered with, the installation remains secure, as the relay is not exposed.

The Secure Relay is available in seven versions, depending on the application. Up to five Secure Relays can be simultaneously connected to a single Wiegand output on a terminal. When a user’s ID is within the specified version’s range as defined on the applicable Secure Relay transacts, that Secure Relay is automatically triggered.

Secure Relay has a variable relay time from 0,2 up to 5 seconds. It also has a built-in optional ‘request to exit’ input.
