Things You'll Need:
- ceiling mounted motion detector
- tools
-
Step 1
Find the range and coverage angle for your ceiling mount motion detector. Compare these specs to the dimensions of the room to plan out the best place to install the detector.
-
Step 2
Determine if your ceiling mount motion detector is meant to install flush with the surface of the ceiling, which will require you to cut out a piece of the ceiling material.
-
Step 1
Measure the outside dimension of the part of the detector that will go inside the ceiling. Transfer this measurement to ceiling.
-
Step 2
Cut away the ceiling material with a saw or electric cutter.
-
Step 3
Place the motion detector against the ceiling and screw into place. Turn on the system and test.
-
Step 1
Transfer the relative location of the screw holes on the back of the ceiling mount motion detector to the surface of the ceiling. Drill pilot holes. You may have to install drywall anchors for a strong, secure attachment.
-
Step 2
Make the attachment. Turn on the system and test.
