IF THIS SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
During an alarm, you will hear a loud, repeating horn pattern:
3 beeps, pause, 3 beeps, pause.
• 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 disconnect the AC power to quiet an unwanted alarm.
Disconnecting the power disables the Alarm so it cannot sense
smoke. This will remove 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.
• ELECTRICAL SHOCK HAZARD: Attempting to disconnect the power
connector from the unit when the power is on may result in electrical
shock, serious injury or death.
When an interconnected system of AC powered units is in alarm, the alarm
indicator light on the unit(s) that initiated the alarm will blink rapidly. It will
remain OFF on any remaining units.
If the unit alarms, get everyone out of the dwelling immediately.
If the unit alarms and you are certain that the source of smoke is not a fire—
cooking smoke or an extremely dusty furnace, for example—open a nearby
window or door and fan the smoke away from the unit (Use the Silence
Feature to silence the Alarm). This will silence the alarm, and once the smoke
clears the unit will reset itself automatically.
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 "Limitations of Smoke Alarms" for
details.
USING THE SILENCE FEATURE
The Silence Feature can temporarily quiet an unwanted alarm for up to 15
minutes.
The Silence Feature does not disable the unit—it makes it temporarily
less sensitive to smoke. For your safety, if smoke around the unit is
dense enough to suggest a potentially dangerous situation, the unit will
stay in alarm or may re-alarm quickly. If you do not know the source of
the smoke, do not assume it is an unwanted alarm. Not responding to an
alarm can result in property loss, injury, or death.
To silence Smoke Alarms in an interconnected series:
1. To silence multiple alarms in an interconnected series, you must press the
Test/Silence button on the unit(s) that triggered the alarm.
2. Once you activate the Silence feature, the Red LED will continue to flash
rapidly.
3. Pressing the Test/Silence button when in silence will restart the silence
timer.
The Silence Feature on these units can temporarily quiet an unwanted alarm
for up to 15 minutes. To use this feature, press the Test/Silence button on the
cover. If the unit will not silence and no heavy smoke is present, or if it
stays in silence mode continuously, it should be replaced immediately.
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 appliances (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.
Your First Alert ® ONELINK ® Smoke Alarm will automatically communicate
potential fires with all other First Alert ® ONELINK ® Smoke Alarms.

SILENCING THE LOW BATTERY WARNING
This 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.
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!
To deactivate this feature: Press the Test/Silence button again. The unit will
go into Test Mode and the low battery warning will resume (LED flashes and
unit sounds “chirp” once a minute).
UNDERSTANDING THE INDICATOR LIGHTS
AND ALARM HORN PATTERNS
NOTE: When power is applied, unit(s) may alarm momentarily.
*When any Smoke Alarm in an interconnected series triggers an alarm, its
red LED will flash rapidly. The red LEDs will remain OFF on any remaining
alarms in the series. This feature helps responders identify which unit(s)
triggered the alarm.
