General Description
The XR2 Detector Installation/Removal Tool is designed for
use with System Sensor plug-in smoke detectors. This tool
permits installation and removal of detectors in elevated
mounting locations up to 18 feet (5.5 meters) high when it
is used with XP-4 extension poles (ordered separately).
Tool Assembly And Disassembly
The XR2 installation/removal tool consists of a head as-
sembly and connecting tube that is used with a set of XP-4
extension poles sold separately (see Figure 1).
To assemble the tool, attach the head assembly to one of
the XP-4 extension poles by sliding the small end of the top
extension pole into the coupler end of the head assembly. A
hole near the end of the tube on the head assembly fits
over the button of the extension pole to lock the head as-
sembly to the extension pole. The extension poles lock to
each other in the same way.
To disassemble, depress the lock button until the head as-
sembly can be disengaged from the extension poles. The
extension poles can be separated from each other in the
same manner.
Detector Installation
To install a System Sensor plug-in detector into a low pro-
file base:
1. Insert and rotate the detector head into the installation
and removal tool until the detector head bottoms and
snaps into place.
2. Raise the tool to the ceiling until the detector head enters
the mounting base and the locking ears on the detector
head meet the ring inside the mounting base.

3. Rotate the tool clockwise until the locking ears enter
their respective slots.
4. Continue rotating the tool until the detector is fully en-
gaged in the base. When this happens the detector can-
not be rotated any further.
NOTE: For conventional detectors, the detector automati-
cally defeats the locking feature on the shorting
spring in the base and then re-engages it, so that
the next detector receives power from the alarm
system.
5. Carefully pull the tool from the detector head.
Detector Removal
To remove a System Sensor low profile plug-in detector
head from a base:
1. Raise the installation/removal tool to ceiling height, lo-
cate the tool over the detector, and push up and rotate
until the tool snaps onto the detector head.
2. Rotate the tool counterclockwise until the detector dis-
engages from the mounting base.
3. Lower the tool slowly and make certain that the detec-
tor head is disengaged completely.
4. Continue lowering the tool. When the detector head is
at floor level, the detector can be removed from the tool
for inspection, testing, or cleaning.
Notes:
1. On conventional bases, when the detector is removed,
the shorting jumper remains defeated; it does not com-
plete the circuit by connecting the + IN and + OUT
terminals. This should cause a fault or trouble condition
at the panel. The jumper must be set manually.
2. Plug-in bases have a built-in tamper-resist feature that,
if activated, must be disabled before the removal tool
