Tamper-resistance Feature

Do not use the tamper-resistance feature if the XR5 removal

feature that, when activated, prevents removal of the detec-

tor without the use of a tool.

To activate this feature, simply break off the tab on the

detector base shown in Figure 3A, then install the detector.

To remove the detector from the base once the tamper-

resistance feature has been activated, place a small-bladed

screwdriver into the small hole on the side of the base and

decorative ring.

The tamper-resistance feature may be defeated by breaking

and removing the plastic lever from the base, however this

prevents ever using the feature again.
