Mounting
JUNCTION BOX
1. Pull the wire through the wall and out the junction box, leaving about six
inches free. Pull the wire through the hole in the base plate.
2. Secure the base to the box using the #6-32 x 5/8 inch mounting screws
provided.
3. Terminate the unit according to the guidelines in the
Termination
section.
4. Attach Cover by latching it to the top of the base, rotating the cover down
and snapping it into place.
5. Secure the cover by backing out the lock-down screws using a 1/16” Allen
wrench until they are flush with the bottom of the cover.
DRYWALL MOUNTING
1. Place the base plate against the wall where you want to mount the sensor.
Mark the two mounting holes and the area where the wires will come
through the wall.
2. Drill two 3/16” holes in the center of each marked mounting hole. Insert a
drywall anchor into each hole.
3. Drill one 1/2” hole in the middle of the marked wiring area. Pull the wire
through the wall and out of the 1/2” hole, leaving about six inches free.
4. Pull the wire through the hole in the base plate.
5. Secure the base to the drywall anchors using the #6 x 1 inch mounting screws provided.
6. Terminate the unit according to the guidelines in the
Termination
section.
7. Attach Cover by latching it to the top of the base, rotating the cover down and snapping it into place. Secure the cover by
backing out the lock-down screws using a 1/16” Allen wrench until they are flush with the bottom of the cover.
NOTE:
In a wall-mount application, the mixing of room air and air from within the wall cavity can lead to erroneous readings,
condensation, and premature failure of the sensor. To prevent this condition, plug the conduit hole with insulation in the
junction box.
