CONNECT CARD READERS
If you have card readers as part of your system, they connect to
TB4 for door one and/or TB6 for door 2 (this can also be the exit
to door 1). You need 5-conductors of 20 to 24 AWG stranded wire
with overall braid shield for these connections.
NOTE: Run cables in metal conduit and ground the conduit
as described in the Installation Tips. Do not run any other wires
in the conduit. Do not use PVC conduit. Special grounding is
required if your installation is near a broadcast tower or
high-tension power lines. Ground both ends of the cable and
conduit as described in the Installation Tips.
WIEGAND READERS
24 AWG cable with both a foil and braid shield is recommended
because it allows the card readers to be mounted up to 500' from
the system. The connections for the Wiegand readers are shown
at right.
BARIUM FERRITE READERS
Use the same type of cable as the Wiegand installation if the
readers are within 125' of the system. If the cable run is longer,
use 20 AWG wire for up to 350' and 18 AWG wire for up to 500'.
Barium Ferrite reader connections are similar to Wiegand reader
connections except for requiring +12 Vdc. Connect the red wire
from each reader to a +12 Vdc terminal on TB5 instead of a +5
Vdc terminal on TB4 or TB6 (see chart at right).
PROXIMITY CARD READERS
24 AWG cable with both a foil and braid shield is recommended
because it allows the card readers to be mounted up to 500' from
the system. The connections for the Proximity card readers are
the same as the Barium Ferrite readers. The connections for the
proximity card readers are shown in the chart at right.
CLIKcard RECEIVERS
24 AWG cable with both a foil and braid shield is recommended
because it allows the Clikcard readers to be mounted up to 500'
from the system. The connection for the Clikcard receivers are as
shown at right.
