NDC-F18 Access Control Panel
The NDC-F18 panel operates as a totally 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 into two doors on a stand-alone basis with no dependency on a central computer system.
A key feature of the NDC-F18 includes its completely distributed database. All card information, time zone information, relay
control information and alarm point information is loaded into the NDC-F18 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 NDC-F18 operates as a stand-alone two-door controller. 32 NDC-F18 panels may be connected via RS485 bus if it is necessary to
increase the system. 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.
NDC-F18 is placed into the rugged steel box with uninterruptible power supply, tamper switch and key lock. It is designated for high security installations and is completely autonomous after the programming.
The NDC-F18 can be programmed and polled by computer using RS-232 communication port. The DcConfigurator programming software is supplied with the controller.
