Mounting hardware is provided for both junction box (J-box) and drywall installation (J-Box installation shown above).
JUNCTION BOX INSTRUCTIONS
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 base to the box using the # 6-32 x 3/4 inch mounting screw provided.
4. Terminate the unit according to the guidelines in Termination on page 2.
5. Attach Cover by latching it to the top of the base, rotating the cover down and snapping it into place.
6. Secure the cover by backing out the lock-down screws using a 1/16” Allen wrench until they are ush with the bottom of the cover.

DRYWALL MOUNTING INSTRUCTIONS
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. 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 Termination on page 2.
9. 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 ush with the bottom of the cover.
NOTE: In a 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, erroneous readings and premature failure of the sensor. To prevent these conditions, seal the conduit leading to the junction box and seal
the hole in the drywall by using an adhesive backed, foam insulating pad (order part number BA/FOAMBACK-ROOM).

Termination
BAPI recommends using twisted pair of at least 22AWG and sealant lled connectors for all wire connections. Larger
gauge wire may be required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes.
Do NOT run this device’s wiring in the same conduit as AC power wiring of NEC class 1, NEC class 2, NEC class 3 or with
wiring used to supply highly inductive loads such as motors, contactors and relays. BAPI’s tests show that uctuating and
inaccurate signal levels are possible when AC power wiring is present in the same conduit as the signal lines. If you are
experiencing any of these difculties, please contact your BAPI representative.
BAPI recommends wiring the product with power disconnected. Proper supply voltage, polarity, and
wiring connections are important to a successful installation. Not observing these recommendations may
damage the product and will void the warranty.
