Tamper-resistance Feature
Do not use the tamper-resistance feature if the XR5 removal
tool is to be used.

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

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

Head removal after the tamper-resistance feature
has been activated first requires removal of the
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.
