ASC2204B-S - control unit for 4 doors

The ASC2202B-S access control unit is used to evaluate the authorization (user authorization is possible by card, code or fingerprint) of users to pass through four doors in one direction or two doors in two directions. This access network controller is equipped with four output relays for door locks. 4 readers with Wiegand 26/34 bit output or RS485 output can be connected. The readers can be connected via Wiegand at a maximum distance of 30 m or via the RS485 interface at a maximum distance of 100 m. The control unit has an internal memory of up to 100,000 users and their authorizations. The ASC2204 also supports sequential lock modes, access bindings, time restrictions, permanent door opening, and more. The controller stores up to 500,000 records, containing not only the history of valid and invalid user authorizations, but also operational states such as opening the door with the exit button, states of door sensors or alarm events (tamper). a friendly software platform that is also common to other DAHUA systems. By deploying several ASC2204B-S control units, even the most extensive access systems can be created.
