The detector bases are supplied with a snap-off locking bar (X) as part of the base moulding
to prevent malicious removal of the detector. The locking mechanism is selectable and is
activated by shifting the U-shaped locking bar (X) into the position as shown in Figure 4.2.

If you mount the detector with a 6-inch base, first remove the base skirt (2) from the
mounting base using a screwdriver to release the 4 tabs (3).
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.
