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

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.

Cable Routing

The cables should run in grounded conduit or at least two feet from AC power,
fluorescent lights, or other high energy sources.
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
CAUTION
or Magnetic door locks without EMI suppression.

Hardware Installation
Maximum Segment Length
Wire should fit within the
enclosure.
4000 feet (1219 m) maximum. All
RDR2S-A modules connected to
a single controller must be within
4000 feet of the controller.
4000 feet (1219 m) maximum
500 ft. (152 m)
Depends on power requirements
of the door strike. Voltage to the
strike must not be reduced more
than 10% over the 18 AWG wire,
measured when energized.
500 feet (152 m)
Refer to reader manufacturer's
specification for power
requirements.
500 ft. (152 m). Refer to reader
manufacturer's specification for
data requirements.
500 feet (152 m)
Depends on load.
