Wiring Inputs to the RM
All input switches can be located up to 2,000 ft. (609.6 m) from the main
apC/L module.
Supervised inputs can be either normally open or normally closed.
Use twisted, 18 AWG (0.902 mm) Belden #8461 or twisted 22
AWG (0.357 mm) Belden #8442 to connect the input switches to
the input pins. Place a piece of wire across the screw terminals of
any unused active unsupervised inputs.
Other types of inputs are:
n
Unsupervised inputs, which are normally closed
n
AC power fail input, which is normally closed
n
Front and rear tamper switches, which are normally closed
To wire the RM to the apC/L:
1. For the data line, pull a twisted shielded pair, 24 AWG Belden #9841
from the apC.
For the power line, pull a twisted pair, 18AWG (0.902 mm) Belden
#8461 or 22AWG (0.357 mm) Belden #8442.
CAUTION
Improper grounding can result in reader failure or
equipment damage. Follow all instructions for
grounding to ensure successful operation of your
readers.
CAUTION
See Appendix B of this manual to determine the
maximum wire length for readers without an
independent power source.
