Cable Routing
All low-level input cables, such as system data and reader cables, must be shielded
types. The cables should run in grounded conduit or at least two feet from AC
power, fluorescent lights, or other high energy sources.
!
CAUTION
All data cables should be physically separated from power lines. If
conduit is used, do not run data cables in the same conduit as power
cables or certain door strike cables, e.g. strike voltage greater that 42V
or Magnetic door locks without EMI suppression.
All cables must conform with the following regulations:
National Electrical Code
NFPA 70
Local electrical codes
Canadian Electric Code C22.1 (installations in Canada)
BSI Standard BS7671, latest edition (installations in Great Britain)
Cabling should be made using good wiring practices and should be long enough to
allow service loops at their termination
s in the enclosure.
CK720 to RDR2S Cable
A cable (part number 25-2360-8) is included with the RDR2S. Use this cable to
fabricate the cable between a CK720 and the RDR2S. Cut the cable in half and
extend the wiring from the CK720 enclosure to the RDR2S.

Depends on load.
1. When wiring more than one RDR2S, use the same type
of hook-up wire and communications
wire to connect subsequent modules.
