Installing Diode for Lock Wiring - Relay

A diode is supplied with the VBB-NRI which should be fitted across 12V and COM to protect the relay contacts.
The lock is wired across 12V and COM. A 0V link to COM is then required to complete the circuit. This will be
wired to NO or NC depending on lock type: Fail Open / Fail Closed (diagram above shows Fail Open).

Upgrading Firmware

With v10 and higher of the VBB-NRI it is possible for the user to update the firmware using the TFTP update
through a telnet session.
To update the firmware:
1 Open the command line.
2 Navigate to the location of the update file.
tftp –i "VBB-NRI IP Address" put "filename"
3 Enter ;
