Dahua ASC2204C-S — 4-Door Networked Access Controller
The Dahua ASC2204C-S is a 1-way networked access controller that manages up to four doors from a single panel. It connects to external card readers via 4 Wiegand ports and links to other system devices over 5 RS485 ports, making it the central control unit in a multi-door access control installation rather than a reader itself.
Who is it for?
This controller suits installers and end users building or expanding a networked access control system across up to four doors. Because it is a controller and not a reader, it must be paired with separate Wiegand card readers or keypads wired into its Wiegand ports, along with electric locks and a power supply, to form a complete working door entry point.
