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 r
eceived to all other ONELINK
®
Alarms. Interfer
ence from
structural conditions can be over
come by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
var
y depending on its sur
r
oundings. It is very important that
each Alarm is tested individually before and after installation
to make sur
e that all Alar
ms respond properly.
•
The
ONELINK
®
Alar
ms ar
e 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 inter
fere 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.

All First Aler
t
®
Smoke Alar
ms conform to regulatory requirements,
including UL217 and ar
e designed to detect par
ticles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally mor
e 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 lar
ge particles, which tend to be pr
oduced
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.
