NDCF16 Access Control Panel
The NDCF16 panel operates as a totaly stand-alone unit with a fully distributed database. All valid card numbers, time zones and relay pulse times are loaded into the controller's memory. The panel controls access to two doors on a stand-alone basis with no dependency on a central computer system.
A key feature of the NDCF16 includes its completely distributed database. All card information, time zone information, relay control information and alarm point information is loaded into the NDCF16 memory. The unit can operate as completely stand-alone with no dependence on any other equipment. The most important feature of any access control system is the ability to be expanded. The NDCF16 operates as a stand-alone two-door controller, and 32 NDC-F16 panels may be connected via RS485 bus if it is necessary to increase the system. Using Golden Gate access control software, a total system is achieved by connecting each drop-line to a communication port or modem or Ethernet terminal server via NDC-B052 network access control panel.
The NDCF16 is placed into the rugged steel box with uniterruptable power supply, tamper switch and key lock. It is designated for high security installations and is completely autonomous after the programming.
The NDCF16 can be programmed and polled by computer using RS-232 communication port. Programming software DcConfigurator is supplied controller.
