Eight-Door Concentrator
Keri Systems KDC-8 Eight-Door Concentrator places four controllers into one cabinet, reducing
the amount of space needed to mount four controllers. The concentrator is designed to fit in a
standard IT server/telecom rack, but can easily be wall mounted. There are knock-outs around the
outside of concentrator's enclosure for cable routing.

  • Page 1 Eight-Door Concentrator Keri Systems KDC-8 Eight-Door Concentrator places four controllers into one cabinet, reducing the amount of space needed to mount four controllers. The concentrator is designed to fit in a standard IT server/telecom rack, but can easily be wall mounted. There are knock-outs around the outside of concentrator’s enclosure for cable routing.
  • Page 2 Eight-Door Concentrator Through the Cabinet Mounting The easiest mounting method is wall mounting through mounting holes within the cabinet. There are three key-hole screw slots and three screw through-holes for secure mounting. Have an assistant hold the unit in the desired mounting place and mark the mounting locations, see Figure 2 (if there are controllers in the cabinet, please remove them before mounting the enclosure).
  • Page 3 Eight-Door Concentrator Bracket Wall Mounting Attach the brackets to the rear of the cabinet sides (see Figure 3). Have an assistant hold the unit in the desired mounting place and mark the mounting locations. Drill pilot holes in the marked locations.
  • Page 4 Eight-Door Concentrator Have an assistant hold the unit in the desired mounting place and mark the mounting locations (see Figure 4). Drill pilot holes in the marked locations and then install the unit. Note: When fully loaded, the unit weighs 19 pounds (before cabling). Mount the unit securely against the wall using molly-bolts or by securing at least two mounting screws to a wall stud.
  • Page 5 Eight-Door Concentrator Rack Mounting The cabinet is designed to be installed in a standard IT Server/Telecom rack using the two rack- mount brackets. Attach the brackets to the sides of the cabinet (see Figure 5). Figure 5: Attaching the Brackets to the Enclosure for Rack Mounting 2305 Bering Drive 01959-001 Rev.
  • Page 6 Eight-Door Concentrator Have an assistant hold the cabinet in the desired mounting place on the rack and secure the cabinet using the rack mount screws (see Figure 6 and Figure 7 – a generic rack configuration is shown, your rack may be slightly different).

  • Page 7: Configuration And Wiring

    Eight-Door Concentrator Configuration and Wiring It takes a lot of cabling to support all eight doors in the cabinet. Knockouts are provided on all four sides, cabinet providing maximum flexibility for routing cables. Cabinet configuration is kept simple. The only jumpers of which to be aware are the external door lock power jumpers, and there are two front-cover LED cables.

  • Page 9 Eight-Door Concentrator Cabinet Cover Power LED The cabinet cover Power LED cable is connected at the factory. It is the left LED on the face of the cabinet (see Figure 1 on page 1). Should the cable come free, connect the cable to J28 pins 1 and 2 with the RED wire connected to pin 1.
  • Page 10 Eight-Door Concentrator Individual Controller Wiring Connections Around the perimeter of the PCB is a ring of 32 connectors. Each connector on the four controllers/ satellite boards has a corresponding connector on the perimeter ring – eight connectors for each controller/satellite board. Figure 10 shows the location of the connector set for each controller/ satellite board.
  • Page 11 Eight-Door Concentrator 3.4.1 A-Reader, B-Reader (TB5 and TB6) Controllers will either be Keri Proximity (PXL-500P - see Figure 11) or Wiegand (PXL-500W - Figure 12). Make the wiring connections from the Reader to the appropriate connector accordingly: A-Reader to TB5, B-Reader to TB6. Use Figure 10 on page 10 to locate the correct connector locations for each controller.
  • Page 12 Eight-Door Concentrator 3.4.2 A-Door: Lock Relay, Alarm Relay Outputs (TB3) Make the wiring connections for the A-Door Lock and Alarm Relays (TB3). Use Figure 10 on page 10 to locate the correct connectors for each controller. For the Lock Relay, power is applied to the common line. This provides flexibility, allowing you to provide power to the lock depending upon the type of lock you have.
  • Page 13 Eight-Door Concentrator 3.4.3 B-Door: Lock Relay, Alarm Relay, General Purpose Outputs 1 and 2 (TB7) TB7 can serve one of two purposes depending upon the configuration of the controller’s satellite board: as the B-Door Lock Relay and Alarm Relay OR as general purpose outputs 1 and 2. Make the wiring connections for either Lock/Alarm Relay usage or for general purpose outputs (TB7).
  • Page 14 Eight-Door Concentrator 3.4.4 A and B-Door Held Open Outputs, General Purpose Outputs 3 and 4 (TB10) TB10 can serve one of two purposes depending upon the configuration of the controller’s satellite board: as the A and B Door Held Open Outputs OR as general purpose outputs 3 and 4. Make the wiring connections for either Door Held Open Relay usage or for general purpose outputs as required.
  • Page 15 Eight-Door Concentrator 3.4.5 A-Door: Status Switch, Request to Exit, Auxiliary Request to Exit, Global Unlock Inputs (TB4) Make the wiring connections for the A-Door Status Switch and Request to Exit inputs (TB4).
