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.

INTRODUCTION
Thank you for choosing First Alert
®
for your Smoke and Carbon
Monoxide Alarm needs. You have purchased a state-of-the-art Smoke &
Carbon Monoxide Alarm designed to provide you with early warning of a
smoke and/or Carbon Monoxide danger. Key features include:
Smoke & Carbon Monoxide Combination Alarm.
One alarm protects
against two deadly household threats.
ONELINK
®
Enabled. Alarm automatically communicates with other
ONELINK
®
enabled alarms when installed.
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.
Spread Spectrum Horn Tone. Lower and varying horn frequency
makes it easier for elderly with normal age related hearing loss to hear
horn. Sweeps through the 2200 – 3400 Hz range.
RF Interconnect. Reliable and secure radio frequency communication
between alarms. 915 MHz frequency with 65,000 security codes and 3
channel frequency hopping.
Single Button Test/Silence eliminates confusion. Depending on what
mode the alarm is in, pushing the button provides different functions
such as testing the alarm, silencing the alarm, re-testing the alarm when
in silence and clearing the Latching features.
Two Silence Features. Temporarily silence low battery chirp for up to
eight hours before replacing low battery or silence an unwanted alarm
for several minutes.
Two Latching Features. Alarm Latch: Easily identifies initiating alarm
even after alarm condition has subsided. Low Battery Latch: Identifies
which unit is in low battery condition.
Perfect Mount System includes a gasketless base for easy installation
and a mounting bracket that keeps the alarm secure over a wide
rotation range to allow for perfect alignment.
6 Year End of Life Timer. Every 24 hours of operation a counter stored
in memory is updated. When the count equals 6 years of true operation,
meaning actually powered-up, a malfunction chirp (triple chirp) will
sound once a minute at the time of the 45 second Power-LED flash.
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.
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.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.
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.
