the threaded mounting post to drill the mounting hole. Press the cutter end of the
post firmly against the tile and twist the post into the tile.
3. Feed sensor wire through the mounting post, then twist and lock the mounting
post to the back of the sensor.
4. Insert the mounting post into the hole drilled in step 2. Secure the sensor
assembly away from the top of the ceiling tile using the supplied washer and lock
nut.
5. Wire the sensor (see Wiring section). Follow applicable national and local electrical
codes.
