The LPU8110NT, (KEYKING, 3 Series Elevator Controller, 16 Floors, 1 Reader, TCP/IP Enabled) is a fully intelligent Ethernet enabled controller based on a 8 bit microprocessor. It is compatible with both the V3.5 Economy and V4 Advanced range of KEYKING 3 Series access controllers (please refer to top left photo). The LPU8110 can by itself control 16 floors with no additional hardware.


The LPU8110NT is a fully intelligent lift/elevator controller which can control access to each floor individually, based on an event or time period. It allows cardholders to select the floor(s) that they are allowed to enter, and the system will record each transaction. It provides many auditing reports, such as data on selected floors to ensure complete accountability. The system can be fully operational in a standalone mode, even during communication loss to the host PC. In offline mode, the controllers will have access to time schedules, authorization groups and even holidays and there will be no additional access level limitation


The LPU8110NT Lift Controller is very versatile and is suitable for other applications as well as Lift/Elevator control. These applications include floor control management, VIP cabinet management and employee locker control.

The diagram below shows how 4 x LPU8110NT Lift Controllers are connected via a Switch Hub to a computer running Sphinx4 Integrated Security Systems software. In this diagram the lift controller and the card reader are housed in the lift car. Note that this is only one option as many lift companies prefer to locate the 3rd party lift controllers in the Lift Machine room with only the actual card reader being located in the lift. As long as the security installation company has the ability to interface to the lift buttons then the location of the controller is secondary.
