GATE OPERATOR MODEL SL 1000-X3 OPTIONS
LOOP DETECTOR ADD-ON BOARDS
Interrupts and Exit loops can be used to enhance safety, security and convenience. The
model SL 1000 has connectors for four LiftMaster-supplied loop detector add-on boards.
These boards interface with Interrupts and Exit loop sensors, which simply plug into the
control board. The add-on boards can be ordered pre-installed, or can be installed in
existing model SL 1000 units. See Figure 22 below for a sample layout.
