HOOKING UP REMOTE KEYPADS/KEYPAD LIGHTS
KEYPADS
Require a 7-conductor, 20-24 AWG, shielded cable. We suggest
with both foil and braid shield or equivalent.
Each Infinity unit may have up to two remote keypads attached.
• In "L", "S", or "DI" systems the main keypad is built into the
unit faceplate and the auxiliary keypad is remote from the
system.
• In "B" system, both keypads are remote from the system.
• All remote keypads must be within 500 feet of the Infinity. The
required cabling and connections for each element of the
keypad assembly is shown below. If you do not have the
optional lighted housing, ignore the section on lights.
NOTE: Cables must be run in metal conduit. Ground the conduit
as described in Installation Tips. Do not run any other wires in
this conduit and do not use PVC conduit.
AT THE KEYPAD HOUSING
1. Plug the keypad cable into J1 on the keypad board (1100017)
from either direction.
NOTE: On the terminal board, you will need to connect the wires
in the same order, i.e., pin 1 at J1 to pin 1 at TB1, pin 2 to
pin 2, etc...
2. Connect the shield to the ground point on the cabinet.
AT THE INFINITY
1. On the main circuit board, connect the keypad cable wires in
the same order as on the keypad board, i.e., pin 1 at J1 to pin
1 at TB 1, pin 2 to pin 2, etc.
2. TB 14 is for "Remote Keypad A" and TB 15 is for "Remote
Keypad B". Remote Keypad A activates relay 1. Remote
Keypad B activates relay 2.
3. Connect the cable shield to the ground screw shown in
Figure 6 or Figure 7.

LIGHTS
Require a 2-conductor, unshielded cable. Use 18 AWG wire for
distances up to 500 feet and 16 AWG for longer runs. Do not run
lighting wires and keypad cable in the same conduit.
AT THE KEYPAD HOUSING
Wire the two lamps in parallel and connect to the unshielded pair.
AT THE INFINITY
Connect the pair to the 12 VAC power on TB 1 of the Infinity's
main board. If you must connect multiple cables to TB1, wire nut
the conductors together off the board and connect a single
18 AWG wire to TB 1. Repeat for the other conductor from
each cable.
HOOKING UP CARD READERS
If you have card readers as part of your Infinity system, they
connect to TB 4 for door one and/or TB 6 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: Cables must be run in metal conduit. Ground the conduit
as described in the Installation Tips. Do not run any other wires
in this conduit and 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 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 feet from the system. The connections for the
Wiegand readers are shown below:
