WHERE THIS ALARM SHOULD NOT BE INSTALLED
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.
OPTIONAL LOCKING FEATURES
The optional locking features are designed to prevent unauthorized removal of the batteries 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 Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Do NOT locate this Smoke/CO Alarm:
USER’S MANUAL
This user’s manual contains important information about your
Combination Carbon Monoxide & Smoke Alarm’s operation. If you are
installing this Alarm for use by others, you must leave this manual—or
a copy of it—with the end user.

Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
Horn: Silent
CO LED: Off
When You Test the Alarm
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.

INTRODUCTION
Alarm Levels of CO are Detected
•
This combination Smoke/Carbon Monoxide Alarm has two
separate alarms. The CO Alarm is not designed to detect fire
or any other gas. It will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be
present in other areas. The Smoke Alarm will only indicate the
presence of smoke that reaches the sensor. The Smoke Alarm
is not designed to sense gas, heat or flames.

to test correctly, have it replaced immediately! If the Alarm is
not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations
of family living units. It is not designed to measure CO levels
in compliance with Occupational Safety and Health
Administration (OSHA) commercial or industrial standards.
Individuals with medical conditions that may make them more
sensitive to carbon monoxide may consider using warning
devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional
information on carbon monoxide and your medical condition
contact your physician.
Exclusive Voice Warning with Location will tell you the preprogrammed
location of the initiating unit and danger detected. Programmable up to
11 locations (ex. "basement"). When alarms sounds, if programmed for
basement it will say "Warning, evacuate, smoke in basement" along with
all other installed ONELINK® Voice alarms.

WHAT TO DO FIRST–IDENTIFY THE TYPE OF
ALARM SIGNAL
Refer to previous section “What You Will See and Hear With This
Alarm”.
This combination Smoke/CO Alarm was designed to be mounted
on the ceiling or wall. It is not a tabletop device. You must install this
device on the ceiling or wall as outlined below. Read “Where To Install
This Alarm” before starting.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm on
every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
•
•
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/CO
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 auto-
matically.

Alarm Will Say:
•
If the unit alarms get everyone out of the house immediately.
1. Insert batteries (2, AA batteries).
“Welcome, First Alert Smoke and
Carbon Monoxide Alarm.”
Consumer Affairs: (800) 323-9005 • www.firstalert.com
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
WHAT TO DO IN CASE OF FIRE
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!
“No location programmed” if first
time or “[Location, example:
“Basement”] location programmed”
when changing batteries.
“To select location, press and hold

Tools you will need: pencil, drill with 3/16” or 5mm drill bit,
Phillips screwdriver, hammer.
®
• Don’t panic; stay calm. Follow your family escape plan.
All First Alert Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
•
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.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for hours
before bursting into flame. Sources of these fires may include cigarettes
burning in couches or bedding.
• 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.
2. Call your emergency services, fire department or 911. Write down the
number of your local emergency service here:

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 tech-
nician to investigate 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:

WIRELESS OPERATION
First Alert® ONELINK® Technology is the easy, cost-effective way to
provide your family with whole-home safety. All ONELINK® Alarms
communicate with each other without wires or connectors. When one
Alarm sounds, they all sound. This provides your family with an earlier
warning of potential danger, and gives you more time to react.
The communication distance (range) between any two ONELINK® Alarms
is typically 50 feet (15 meters) inside of a home. Some features of a
home, such as the number of floors, number/size of rooms, furniture and
types of building materials used may reduce the range of the Alarms.
Examples include: suspended ceilings, ductwork, large metallic appli-
ances (refrigerators) and metal studs. A feature of ONELINK® Alarms is
that they operate as a mesh network. All Alarms will repeat any alarm
signal that is received to all other ONELINK® Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.

The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
The ONELINK Alarms are not to be used outdoors or to
transmit between buildings. The Alarms will not communicate
properly under these conditions.
Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.

USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing the batteries
disables the alarm and removes your protection.
The Alarm Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence the Smoke/CO Alarm by pressing the Test/Silence button
on the alarm cover for at least 6 seconds.
After the Test/Silence button is released, the Alarm Voice will say “Horn silenced,
detector active.”
The Low Battery Warning Silence Feature can temporarily quiet the low battery
warning “chirp” for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover for at least 3-5 seconds.
Once the low battery warning “chirp” silence feature is activated, the unit continues to
flash the Green light twice a minute for 8 hours. After 8 hours, the low battery “chirp”
will resume. Replace the batteries as soon as possible; this unit will not operate
without battery power!
