10    Conventional Products—B110LP Plug-In Conventional Low Profile Detector Base

Note: Do not use the tamper-proof capability if the XR2 removal tool

will be used to remove detectors from the base.

This detector base can be made tamper-proof so that the detector cannot be
detached without the use of a tool.

To make the base tamper-proof before installing the detector:

1.

Break off the smaller tab at the scribed line on the tamper-proof tab on
the detector mounting bracket (Figure 4).

To remove the detector from the base after it has been made tamper-proof:

1.

Remove the decorative ring by rotating it in either direction and
pulling it away from the base.

2.

Insert a small screwdriver into the notch (Figure 5).

3.

Press the plastic lever toward the mounting surface before rotating the
detector counterclockwise for removal.

The tamper-proof feature may be defeated by breaking and removing
the plastic lever from the base.  However, this prevents using the
feature again.
