6. Line the mounting bracket up over the
plastic screw anchors.
7. Screw the mounting bracket to the ceiling
or wall through the mounting slots using
the two screws provided.
8. Before attaching the Alarm to the bracket,
insert the 9V battery (included) into the
battery compartment. Match the terminals
on the end of the battery with the termi-
nals on the unit. Match “+” to “+” and “-”
to “-.” Push the battery in until it snaps in
securely and cannot be shaken loose. If
the battery is not snapped in completely,
the unit cannot receive battery power.
NOTE: The unit may beep briefly when you
install the battery. This is normal. 
The GREEN Light flashes about every
30 seconds when the unit is receiving
battery power.
The battery door will not close unless a battery is installed. This warns
you the unit will not operate without a battery.
9. Align the tabs on the base with the tabs on the mounting bracket. 
Turn the base until it snaps into place.
10. If the cover does not line up the way you wanted, adjust it by slowly 
rotating it in either direction.
11. Test the Smoke/CO Alarm. See “Weekly Testing” for details.

IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon monoxide
(CO) which can kill you. In other words, when your CO Alarm sounds, you
must not ignore it!
“ALARM-MOVE TO FRESH AIR”
If you hear the alarm horn sound 4 beeps,
pause, 4 beeps, pause, and the RED CO 
light is flashing, move everyone to a 
source of fresh air. 
IF THE CO ALARM SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down the
number of your local emergency service here:
__________________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or window.
Do a head count to check that all persons are accounted for. Do not re-
enter the premises, or move away from the open door or window until the
emergency services responder has arrived, the premises have been aired
out, and your CO Alarm remains in its normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a 24-hour
period, repeat steps 1-3 and call a qualified appliance technician to inves-
tigate for sources of CO from fuel-burning equipment and appliances, and
inspect for proper operation of this equipment. If problems are identified
during this inspection have the equipment serviced immediately. Note any
combustion equipment not inspected by the technician, and consult the
manufacturers’ instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that motor
vehicles are not, and have not, been operating in an attached garage or
adjacent to the residence. Write down the number of a qualified appliance
technician here:

IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
If the unit alarms and you are not testing the unit, it is warning you 
of a potentially dangerous situation that requires your immediate
attention. NEVER ignore any alarm. Ignoring the alarm may result in
injury or death.
Never remove the batteries from a battery operated Smoke Alarm to
stop an unwanted alarm (caused by cooking smoke, etc.). Removing
batteries disables the alarm so it cannot sense smoke, and removes
your protection. Instead open a window or fan the smoke away from
the unit. The alarm will reset automatically.
If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get 
dressed or collect anything.
• Feel doors with the back of your hand before opening them. 
If a door is cool, open it slowly. Don’t open a hot door. Keep doors 
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp). 
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, 
and do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside. 
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home safer.
Alarms have various limitations. See "General Limitations of Smoke/CO
Alarms" for details.
USING THE SILENCE FEATURE
Never remove the batteries to quiet an unwanted alarm. Removing the
batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while you
identify and correct the problem. Do not use the Silence Feature in emergency
situations. It will not correct a CO problem or extinguish a fire. 
To use the Silence Feature, press and hold the Test/Silence button on the
cover of the Smoke/CO Alarm for 3 seconds.
If you hear the alarm horn sound 3 beeps, pause, 
3 beeps, pause and the RED SMOKE light is flash-
ing, smoke has been detected. Evacuate everyone
from the building. 
When the Smoke Alarm is Silenced  
When the CO Alarm is silenced
The Smoke Alarm will remain silent
for 8 minutes, then return to normal
operation.
If the smoke has not cleared–or con-
tinues to increase–the device will go
back into alarm.
The CO alarm will remain silent for 
4 minutes.
After 4 minutes, if CO levels remain
potentially dangerous the horn will
start sounding again.
