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.

1. When wiring more than one RDR2S-A or I8O4, use the same type of hook-up wire and communications
wire to connect subsequent modules.
2. Refer to reader manufacturer’s recommendations when using UL-listed readers. In the absence of other
recommendations, consider these cable specifications taking into account the number of conductors that
will actually be needed for installation.
