Step 1
Turn the alarm sensor so the back of its plastic case is facing you. Sand the center of the back lightly with a piece of 120-grit sandpaper, to create texture that will assist in the adhesive bonding process.
Step 2
Wipe the sanded area with a dishcloth to remove any loose grit.
Step 3
Squirt a quarter-sized dollop of a clear silicone-type adhesive to the area of the sensor you sanded.
Step 4
Press the back of the alarm sensor to the vinyl window at the desired location. Hold the alarm sensor in place for three minutes.
Step 5
Do not disturb the alarm sensor for at least 24 hours while the adhesive bonds with the vinyl window’s surface.
