APPENDIX B

PARALLEL GATE WIRING

While it is strongly recommended that the Master/Slave function be used in any dual-unit installation,
two LiftMaster model SW 2000-B1's may be parallel-wired

as Bi-Parting gates only

NOTES:

1. When parallel wiring the RADIO INPUT terminals, do not connect the POWER output from one

board to the POWER output on the other board.

Failure to observe this will damage both controller boards.

2. Do not parallel wire the MAGLOCK terminals.

Auxiliary device circuits may be damaged if

separate auxiliary devices are used with each board.

3. Both gate operators must have the same settings for:

a. Gate Setting Switch S1

b. Reclose Timer Pot

c. Current Sensitivity pots (Left & Right Reverse, Inrush)

Limit

Cams

CAUTION

The Signal and Common terminals on one board MUST connect to the corresponding Signal and
Common terminals on the other board.

Failure to observe this will damage both controller

boards.

DO NOT INTERCHANGE SIGNAL AND COMMON TERMINALS
