Tighten the base to the mounting surface. Do not over tighten. If you use a 6-inch base, fit
the base skirt onto the mounting base.

Tuck it into the opening next to it by pushing hard.
Insert the detector head into the base.
Release the locked detector head by pushing hard through the dimple (O) on the

to the left.
