The 020-643 is a dual-port fibre optic interface card for the Notifier ID²net network used by ID3000 panels. It plugs directly into the network gateway module (NGM, 020-647) via a ribbon cable and provides two fibre optic ports (left and right channel). Only one is needed per NGM, for fibre-to-fibre or fibre-to-wire links. Fibre is recommended for distances over 500 m or industrial environments.
