Mounting
Mounting hardware is provided for both junction box and drywall instal-
lation (junction box installation shown).
Note: Screw the 1/26” Allen lock-down screw into the base to open the
case, less chance of losing it this way. Back out the lock-down screw
to secure the cover.
Junction Box
1. Pull the wire through the wall and out of the junction box, leaving
about six inches free.
2. Pull the wire through the hole in the base plate.
3. Secure the plate to the box using the #6-32 x 5/8 inch mounting
screws provided.
4. Terminate the unit according to the guidelines in the Termination
section. (page 3)
5. Mold the foam on the unit’s base to the wire bundle to prevent
drafts. (see note below)
6. Attach Cover by latching it to the top of the base, rotating the cover
down and snapping it into place.
7. Secure the cover by backing out the lock-down screw using a
1/16” Allen wrench until it is flush with the bottom of the cover.
Drywall Mounting
1. Place the base plate against the wall where you want to mount the sensor.
2. Using a pencil, mark out the two mounting holes and the area where the wires will come through the wall.
3. Drill two 3/16” holes in the center of each marked mounting hole, DO NOT punch the holes or the drywall an-
chors will not hold. Insert a drywall anchor into each hole.
4. Drill one 1/2” hole in the middle of the marked wiring area.
5. Pull the wire through the wall and out of the 1/2” hole, leaving about six inches free.
6. Pull the wire through the hole in the base plate.
7. Secure the base to the drywall anchors using the #6 x 1 inch mounting screws provided.
8. Terminate the unit according to the guidelines in the Termination section. (page 3)
9. Mold the foam on the unit’s base to the wire bundle to prevent drafts. (see note below)
10. Attach cover by latching it to the top of the base, rotating the cover down and snapping it into place.
11. Secure the cover by backing out the lock-down screw using a 1/16” Allen wrench until it is flush with the bottom
of the cover.
NOTE: In any wall-mount application, the wall temperature and the temperature of the air within the wall cavity can
cause erroneous readings. The mixing of room air and air from within the wall cavity can lead to condensation, er-
roneous readings and sensor failure. To prevent these conditions, BAPI recommends sealing the conduit leading to
the junction box, filling the junction box with fiberglass insulation or sealing the wall cavity.
