Tamper-resistance Feature
CAUTION
Do not use the tamper-resistance feature if the XR5 removal
tool is to be used.
This detector base includes an optional tamper-resistance
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 de-
tector base shown in Figure 3A, then install the detector. To
remove the detector from the base once the tamper-resis-
tance feature has been activated, place a small-bladed
screwdriver into the small hole on the side of the base and
Figure 2. Typical wiring diagram:

CLASS A OPTIONAL WIRING
push plastic lever away from the detector head (see Figure
3B). This will allow the detector to be rotated counterclock-
wise for removal.
NOTE: 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.
