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.
WIRELESS OPERATION
First Alert® ONELINKTM Technology is the easy, cost-effective way to provide your family with whole-home safety. All ONELINKTM 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 ONELINKTM 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 ONELINKTM Alarms is that they operate as a mesh network. All Alarms will repeat any alarm signal that is received to all other ONELINKTM 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 ONELINKTM 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® ONELINKTM Smoke Alarm will automatically communicate potential fires with all other First Alert® ONELINKTM Smoke Alarms.
FCC NOTICE: This device complies with Part 15 of the FCC Rules.

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.
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).
