CAUTION: This alarm will only indicate the presence
of carbon monoxide gas at the sensor. Carbon
monoxide gas may be present in other areas.

Individuals with medical problems may consider using
warning devices which provide audible and visual signals
for carbon monoxide concentrations under 30 ppm.

Step 1

back of the unit to install batteries.To remove, hold
the mounting plate and twist counterclockwise (left).

• The battery polarity markings on the bottom of the

battery compartment must be adhered to.

• Batteries must be installed in the sequence shown. If

batteries seem difficult to install, they’re not being

A. Recommended Installation Locations:

Kidde Safety recommends the installation of a
Smoke/CO Alarm in the following locations. For
maximum protection we suggest an alarm be installed
on each level of a multilevel home, including every
bedroom, hallways, finished attics and basements. Put
alarms at both ends of bedroom, hallway or large room
if hallway or room is more than 30ft. (9.1m) long. If you
have only one alarm, ensure it is placed in the hallway
outside of the main sleeping area, or in the main bed-
room. Verify the alarm can be heard in all sleeping
areas.

Locate an alarm in every room where someone sleeps
with the door closed.The closed door may prevent the
alarm from waking the sleeper. Smoke, heat and com-
bustion products rise to the ceiling and spread
horizontally. Mounting the alarm on the ceiling in the
center of the room places it closest to all points in the
room. Ceiling mounting is preferred in ordinary residen-
tial construction.When mounting an alarm on the
