Cable Routing
The cables should run in grounded conduit or at least two feet from AC
power, fluorescent lights, or other high energy sources.
IMPORTANT: 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 terminations in the enclosure.
Power Wiring
The CKM-MR52 accepts 12 to 24 VDC for power on TB7. Locate the
power source as close to the CKM-MR52 as possible. Make power
connection with minimum of 18 AWG wires.
