on the length, angle, etc. of the ceiling's slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
• This unit will not alert hearing impaired residents. It is
recommended that you install special units which use devices
like flashing strobe lights to alert hearing impaired residents.
• This Smoke/CO Alarm cannot operate without working
batteries. Removing the batteries for any reason, or failing to
replace the batteries at the end of their service life, removes
your protection.
• The battery compartment resists closing unless a battery is
installed. This warns you the unit will not operate without a
battery.
• Do not stand too close to the unit when the alarm is sounding.
It is loud to wake you in an emergency. Exposure to the horn
at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the
sensing chambers and prevent the unit from operating properly.

BEFORE YOU BEGIN INSTALLATION
This combination Smoke/CO Alarm was designed to be mounted
on the ceiling or wall. It is not a tabletop device. Read "Where to
Install This Alarm" and "Where This Alarm Should Not Be Installed"
before you begin installation.
Find the pair of self-adhesive labels included with this Smoke/CO Alarm.
• On each label write in the phone number of your emergency
responder (like 911) and a qualified appliance technician.
• Place one label near the Smoke/CO Alarm, and the other label in
the "fresh air" location you plan to go if the alarm sounds.
HOW TO INSTALL THIS SMOKE/CO ALARM
Tools you will need: Pencil, drill with 3/16" (5mm) drill bit,
flathead screwdriver, hammer.
• Do not connect this unit to any other alarm or auxiliary device.
It is a single-station unit that cannot be linked to other devices.
Connecting anything else to this unit may prevent it from working
properly.
• Do not install this unit over an electrical junction box. Air currents
around junction boxes can prevent smoke from reaching the
sensing chamber and prevent the unit from alarming. Only AC
powered units are intended for installation over junction boxes.
To install this unit:
If you want to lock the battery compartment, or lock the Smoke/CO
Alarm to the mounting bracket, please read the "Optional Locking
Features" section.
SUGGESTED AREAS FOR INSTALLING
SMOKE ALARMS, CO ALARMS, AND COMBO UNITS
1. Hold base firmly and twist the mounting bracket counterclockwise
(left) to separate it from the unit.
KEY:
2. Hold the mounting bracket against the ceiling (or wall) so the
SMOKE ALARMS vertical mounting slot is aligned in the 12 o'clock position and trace
around the inside of the mounting slots (vertical and horizontal

mounting holes.
BOTH, OR COMBINATION
SMOKE/CO ALARMS
Suggested locations are based on
NFPA recommendations (NFPA 72
for Smoke Alarms and NFPA 720 for
Carbon Monoxide Alarms). Always
refer to national and local codes
before beginning any installation.
The optional locking features are designed to discourage unauthorized
removal of the battery or alarm. It is not necessary to activate the locks
in single-family households where unauthorized battery or alarm
removal is not a concern.
These Smoke/CO Alarms have two separate locking features: one locks
the battery compartment, and the other locks the Smoke/CO Alarm to the
mounting bracket. You can choose to use either feature independently, or
use them both.
Tools you will need: • Needle-nose pliers or utility knife
• Standard/Flathead screwdriver.
Both locking features use locking pins, molded into the mounting bracket. Using needle nose pliers or a utility knife, remove one or both pins, depending
on which locking features you use.
THE BATTERY COMPARTMENT LOCK
TO LOCK THE BATTERY COMPARTMENT:
Do not lock the battery compartment until you have activated the battery
and tested the Smoke/CO Alarm.
1. Activate the battery by removing the
"Pull to Activate Battery" tab. Push and
hold the test button on the Smoke/CO
Alarm's cover until the alarm sounds:
4 beeps, pause, 4 beeps, pause,
3 beeps, pause, 3 beeps, pause.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install a new battery
and test again. If it still does not
alarm, replace the Smoke/CO
Alarm immediately.
2. Using needle-nose pliers or a utility
knife, detach one locking pin from
the mounting bracket.
3. Push the locking pin
through the black dot on
the label on the back of
the Smoke/CO Alarm.
THE MOUNTING BRACKET LOCK
TO ACTIVATE THE BRACKET LOCK:
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. Insert the locking pin into the lock
located on the base as shown in
the diagram.
3. When you attach the
Smoke/CO Alarm to the
mounting bracket, the
locking pin's head will fit
into a notch on the bracket.

4. Using a 3/16" (5 mm) drill bit, drill a hole through the center of the
oval outlines you traced.
5. Insert the plastic screw anchors (in the plastic bag with screws) into
the holes. Tap the screw anchors gently with a hammer, if necessary,
until they are flush with the ceiling or wall.
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. Position the base of the Smoke/CO Alarm over the mounting bracket
and turn. The Alarm will remain secure over a wide rotation range to
allow for perfect alignment. When wall mounting, this will allow fine-
tuning on the positioning to compensate for out of aligned wall studs
and to keep the wording level. The Alarm can be positioned over the
bracket every 120°. Rotate the Alarm until aligned properly.
9. Test the Smoke/CO Alarm. See "Weekly Testing" for details.

USING THE OPTIONAL LOCKING FEATURES

Locking Pin
Mounting Bracket Lock
TO UNLOCK THE BATTERY COMPARTMENT:
1. Remove the Smoke/CO Alarm from the mounting bracket. If the
unit is locked to the bracket, see the section "To Deactivate the
Bracket Lock."
2. Insert a flathead screwdriver under the head
of the locking pin, and gently pry it out of
the battery compartment lock. (If you plan
to relock the battery compartment, save
the locking pin.)
3. To re-lock the battery compartment, close
the battery door and reinsert the locking pin
in the lock.
4. Reattach the Smoke/CO Alarm to the mounting bracket.
When replacing the battery, always test the Smoke/CO Alarm before
relocking the battery compartment.
TO DEACTIVATE THE BRACKET LOCK:
1. Insert a flathead screwdriver between the mounting bracket pin
and the mounting bracket.
2. Pry the Smoke/CO Alarm away from the bracket by turning both
the screwdriver and the Smoke/CO Alarm counterclockwise (left)
at the same time.
TO PERMANENTLY REMOVE
THE BRACKET LOCK:
Insert the flathead screwdriver
between the locking pin and
the lock, and pry the pin out
of the lock.
