ACS3000-RD4 adopts RS485 and TCP/IP mixed networking mode. It supports 2 two-way doors or 4 one-way doors, 8 inputs and 4 outputs with user-definable functions. It is used for universal inputs such as door sensor, exit button, etc., and can also be used for alarm input of tamper-evident, fire alarm, and output of door lock control, etc.
Various user-configured system parameters such as the cardholder’s access permissions, access records, and access modes are stored in the non-volatile memory chip. Even if the communication with the host is interrupted, the access controller still works normally.
It can initiate communication actively. When the network controller and the computer system are offline or fail, it can execute the fire linkage signal normally and open the fire evacuation door or all doors.
