Important Information About This Smoke/CO Alarm
Required Power Supply
• This combination smoke-CO alarm requires
constant 120-volt, AC power AND/OR a work-
ing 9-volt battery to operate properly. This
combination alarm WILL NOT work if AC
power is not connected or has failed or been
interrupted for any reason AND the battery is
removed, drained or improperly connected.
DO NOT use any other kind of battery except
as specified in this manual.
NOTE: AC/DC combination alarms offer
added protection in the event of a power
failure or a drained battery.
• You may operate this combination smoke-CO
alarm on battery power only. Having only one
source of power is less reliable than having
two different power sources. If the battery is
too weak to power the alarm, or is removed
from the alarm, the alarm will not protect you
from hazardous conditions within your home.
Make sure a battery-only installation complies
with your local codes and regulations. Check
with your local fire department or building
code enforcement department if you are
unsure of the rules.
• DO NOT remove or disconnect battery or turn
off AC power to quiet unwanted alarms. This
will remove your protection. This combination
alarm features a Quick Quiet™ False Alarm
Control™ button which, when activated, will
quiet unwanted smoke alarms for approxi-
mately 10 minutes and quiet CO alarms for up
to 6 minutes.
Coverage
• Install a smoke alarm in every room and on
every level of the home. Smoke may not reach
the smoke alarm for many reasons. For exam-
ple, if a fire starts in a remote part of the
home, on another level, in a chimney, wall,
roof, or on the other side of a closed door,
smoke may not reach the smoke alarm in time
to alert household members. A smoke alarm
will not promptly detect a fire EXCEPT in the
area or room in which it is installed.
Installation/Interconnect
• This combination alarm should be installed
only by a licensed qualified electrician.
Observe and follow all local and national elec-
trical and building codes for installation.
• Interconnected smoke alarms installed in every
room and on every level of the household offer
maximum protection. The National Fire
Protection Agency (NFPA) recommends inter-
connecting smoke alarms so that when one
smoke alarm senses smoke and sounds its
alarm, all others will sound as well. Do not
interconnect smoke alarms from one individual
family living unit to another.
• Unique power connector prevents intercon-
nection with incompatible smoke and combi-
nation alarms or security systems.
