DPU 7920I/NET
® Seven
The door processor unit 7920 (DPU-7920) functions aseither a stand-alone device or as part of a larger local areanetwork (LAN) host system. It controls up to two doors withentry reader inputs, or one door with entry and exit readerinputs, eight universal inputs, and eight relay contactoutputs.
By processing input data with programmed information, theDPU controls access into and exit from an area. It canmonitor the status of the lock and door, routing statusinformation to selected CRT displays and printers, andgenerate fault messages according to its programming.The DPU-7920 supports a total of 48,000 users.
