Dahua DHI-ASC2104B-T Four Door Slave Access Control Module

The Dahua DHI-ASC2104B-T Four Door Slave Access Control Module is an expansion unit designed to significantly increase the capacity of a centralized Dahua access control system. It is specifically a slave controller that must be connected to a compatible Master Controller (such as the Dahua ASC2204-H or ASC2204C-H) via a high-reliability CAN bus.

This module is used in medium to large-scale projects like commercial buildings, industrial parks, and government facilities to manage access for multiple entry points efficiently under a single network IP.
