2. Mount Smoke Detector Backplate
NOTE: The alarm device should only be installed by a competent engineer or technician.
Smoke detectors are not to be used with smoke detector guards unless the combination
has been evaluated and found suitable for that purpose.
Once a suitable location is found, mount the detector backplate. Install the mounting base on
the ceiling or on the wall (if local ordinances permit) using screw locations as required. Use the
two screws and anchors provided. Maneuver the base so the screws are at the elbow of the
screw slots and secure.

minimum
3. Mounting
Fit the detector inside the base by aligning it over the base. The detector's alignment notch
should be slightly offset from the mounting base tamper release tab. Then turn the detector
clockwise until it clicks into place.
If there is a need to activate the built- in anti-tamper lock, carefully remove the breakaway tab on
the backplace as shown in the following figure.
4. Device Enrollment
The 7-digit serial number located on the back of the smoke detector housing must be enrolled
on the alarm systems control panel. See the Receiver Installation Manual and follow the enroll-
ment procedure. For placement tests remove the detector from its backplate for one second
(tamper) and then reattach. Wait at least 30 seconds for the test result before activating again.
