Loop Detector Usage - Chamberlain LiftMaster Professional CB124 Instructions Manual

LOOP DETECTOR
Jumper LOOP / EDGEmust be plugged
Loop detectors react to metal and the most common use is for cars
or trucks but not for bikes or pedestrians.
Exit loop / Gate Opening Loop
An exit loop is behind the gate and opens the gate when closed,
keeps it open or re-opens the gate.
The jumpers OPEN/STEP and LOOP/EDGE must be in position
PLUGGED (in place). The gate requires installed photocells and
the closing of the gate shall be activated by the automatic close
timer.
Safety/Interrupt loop and Shadow loop
Safety loops can be used to detect cars or truck but do not comply
with regulations as single protection since they do not detect
people.
The loop detector control board output is wired as NO signal to the
8.2KOhm safety edge output. In case you use safety edges as well:
Check the functionality you need before installation!
Interrupt loop =>Jumper open-step PLUGGED (in place)
Shadow loop => Jumper OPEN-STEP OPEN (removed)
Other options for loop detectors can be requested from our service
department.
