Wiring: 2-Wire IP
A Dahua digital two-wire intercom switch, not a general-purpose Ethernet PoE switch. Use only compatible Dahua two-wire IP door stations and monitors; do not substitute it for a two-wire hybrid controller.
Existing cable can be reused only after checking conductor size, cable condition, distance, polarity where applicable and the manufacturer’s wiring diagram. Matching the wire count alone does not establish compatibility. Locks, gate controls and their power requirements must be checked separately.
