Loop Detector Usage - Chamberlain LiftMaster Professional SUB324M Instructions

LOOP DETECTOR
Switch on DIP LOOP / EDGE
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 A
An exit loop is behind the gate and opens the gate when closed,
keeps it open or re-opens the gate.
The DIPs OPEN/STEP and LOOP/EDGE must be on. 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 B, C
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 => DIP OPEN/STEP must be on.
Shadow loop => DIP OPEN/STEP must be off.
Other options for loop detectors can be requested from our service
department.
