Loop Installation
NEW SLAB POUR
Ty-wrap 1-
1/4” PVC pipe to the top of the rebar in the
size and configuration of the loop (ex. 4’ x 8’).
Then ty-wrap the loop to the top of the PVC frame.
This stabilizes the loop during the pour and separates
it from the rebar.
SAW CUT EXISTING SURFACE
Cut 1
”
deep into the existing surface, place a 45
°
cut at
the corners to prevent sharp edges from damaging the
loop wire. Notch out for the

”
connection where the
lead wire connects to the loop. Remove all debris from
the finished cut with compressed air. Place the loop
into the saw cut. Place backer material into the
saw cut over the loop wire and pack tightly. Place a
high-quality sealer over the saw cut to seal the surface.
RESURFACE ASPHALT
Saw cut the existing surface ¾” deep and place a 45°
cut at the corners to prevent sharp edges from
damaging the loop wire. Remove all debris from the
finished cut with compressed air. Place sand over the
loop wire to the surface and pack tightly.
Lay new asphalt.
GRAVEL OR SOIL INSTALLATION
While this is not a recommended installation for
most loops, it has been used successfully with
proper preparation. Remove gravel or top soil until
reaching a stable base. Dig ~ 6-8

deep by ~ 6-
8” wide
.
Fill halfway with sand and pack tightly. Place the loop
into the trench and finish filling to level with sand.
Pack tightly and replace gravel or soil over top.
GENERAL INSTALLATION GUIDELINES
•
Use EMX lite preformed loops for quick, reliable installations.
•
It is not recommended to install a loop near power lines (overhead or underground) or low voltage lighting.
If necessary near these power sources, place at a 45° angle. Make the loop shape a diamond, not a square.
•
Never install a loop near inductive heaters.
•
If using a non-preformed loop, lead-in wire (wire from loop to detector) must be twisted a minimum of
6 turns per foot to avoid the effects of noise or other interference.
•
Detection height is approximately 70% of the shortest side of the loop.
For example: detection height for a 4’ x 8’ loop = 48” x .7 = 33.6”
