Installation
Install at least 12" (30.5 cm) away from fluorescent lights
as electronic noise may cause nuisance alarms. Do not
place in direct sunlight and keep out of insect infested
areas. Extreme temperatures will effect the sensitivity of
the Smoke/CO Alarm. Do not install in areas where the
temperature may fall below 4.4°C (40°F) or rise above
37.8°C (100°F), such as garages and unfinished attics.
Do not install in areas where the relative humidity (RH)
is greater than 85%. Place away from doors and
windows that open to the outside.
Mounting
CAUTION: Your Smoke/CO Alarm is sealed and
the cover is NOT removable!
• To help identify the date to replace the unit, a label
has been affixed to the side of the alarm. Write the
"Replace by" date (7 years from power up) in
permanent marker on the label. See "Alarm
Replacement" section for additional details.
• The mounting plate must be removed from the
back of the alarm to install. To detach, twist the
mounting plate and the alarm in opposite directions.
Hold the mounting plate against the selected
installation location (wall or ceiling) and mark the
center of the holes with a pencil.
• To ensure aesthetic alignment of the alarm with the
hallway, or wall, the "A" line on the mounting plate
should be parallel with the hallway when ceiling
mounting, or horizontal when wall mounting. Drill a
hole through the pencil marks and use the enclosed
screws and anchors to secure. Use 3/16" drill for
anchor holes. Align the Smoke/CO Alarm with the
mounting plate and rotate clockwise (right) until the
unit is aligned. Screw and anchor accessories are
supplied.
