 | | DLK642 Access Control Panel
The DLK642 panel operates as a total 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 DLK642 includes its completely distributed database. All card information, time zone information, relay control information and alarm point information is loaded into the DLK642 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 DLK642 will operates as a stand-alone two-door controller, and in case of increase need up to 32 DLK642 panels may be connected on an RS-485 dropline. 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 DLK642 provides for a card database up to 1,024 cards and a transaction buffer capable of storing 1,920 ivents.
The DLK642 is placed into the attractive compact housing with the keypad and built-in reader, making the office installations easy and cost-effective. |
