All First Alert® and BRK® 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.
FIRE SAFETY TIPS
Follow safety rules and prevent hazardous situations: 1) Use smoking materials properly. Never smoke in bed. 2) Keep matches or lighters away from children; 3) Store flammable materials in proper containers;
4) Keep electrical appliances in good condition and don’t overload electrical circuits; 5) Keep stoves, barbecue grills, fireplaces and chimneys greaseand debris-free; 6) Never leave anything cooking on the stove unattended;
7) Keep portable heaters and open flames, like candles, away from flammable materials; 8) Don’t let rubbish accumulate.
Keep alarms clean, and test them weekly. Replace alarms immediately if they are not working properly. Smoke Alarms that do not work cannot alert you to a fire. Keep at least one working fire extinguisher on every floor, and an additional one in the kitchen. Have fire escape ladders or other reliable means of escape from an upper floor in case stairs are blocked.

BEFORE YOU INSTALL THIS SMOKE ALARM
IMPORTANT! Read “Recommended Locations for Smoke Alarms” and “Locations to Avoid for Smoke Alarms” before beginning. This unit monitors the air, and when smoke reaches its sensing chamber, it alarms. It can give you more time to escape before fire spreads. This unit can ONLY give an early warning of developing fires if it is installed, maintained and located where smoke can reach it, and where all residents can hear it, as described in this manual. This unit will not sense gas, heat, or flame. It cannot prevent or extinguish fires.
Understand The Different Type of Smoke Alarms
Battery powered or electrical? Different Smoke Alarms provide different types of protection. See “About Smoke Alarms” for details.
Know Where To Install Your Smoke Alarms
Fire Safety Professionals recommend at least one Smoke Alarm on every level of your home, in every bedroom, and in every bedroom hallway or separate sleeping area. See “Recommended Locations For Smoke Alarms” and “Locations To Avoid For Smoke Alarms” for details.
Know What Smoke Alarms Can and Can’t Do
A Smoke Alarm can help alert you to fire, giving you precious time to escape. It can only sound an alarm once smoke reaches the sensor. See “Limitations of Smoke Alarms” for details.
Check Your Local Building Codes
This Smoke Alarm is designed to be used in a typical single-family home.
It alone will not meet requirements for boarding houses, apartment buildings, hotels or motels. See “Special Compliance Considerations” for details.

BEFORE YOU INSTALL THIS SMOKE ALARM, Continued
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the Smoke Alarm is installed before removing it from the mounting bracket. Failure to turn off the power first may result in serious electrical shock, injury or death.
•This unit will not alert hearing impaired residents. It is recommended that you install special units which use devices like flashing strobe lights to alert hearing impaired residents.
•Installation of this unit must conform to the electrical codes in your area; Articles 210, 760 of NFPA 70 (NEC), NFPA 72, NFPA 101; ICC; SBC (SBCCI); UBC (ICBO); NBC (BOCA); OTFDC (CABO), and any other local or building codes that may apply. Wiring and installation must be performed by a licensed electrician. Failure to follow these guidelines may result in injury or property damage.
•This unit must be powered by a 24-hour, 120V AC pure sine wave 60 Hz circuit. Be sure the circuit cannot be turned off by a switch, dimmer, or ground fault circuit interrupter. Failure to connect this unit to a 24-hour circuit may prevent it from providing constant protection. Unit may be connected to an arc fault circuit interrupter.
•This Smoke Alarm must have AC or battery power to operate.
If the AC power fails, battery back-up will allow the alarm to sound for at least 4 minutes. If AC power fails and the battery is weak, protection should last for up to 7 days. If AC power fails and the battery is dead or missing, the alarm cannot operate.
•Never disconnect the power from an AC powered unit to stop an unwanted alarm. Doing so will disable the unit and remove your protection. In the case of a true unwanted alarm open a window or fan the smoke away from the unit. The alarm will reset automatically when it returns to normal operation. Never remove the batteries from a battery operated unit to stop an unwanted alarm (caused by cooking smoke, etc.). Instead open a window or fan the smoke away from the unit. The alarm will reset automatically.
•Connect this unit ONLY to other compatible units. See “How To Install This Smoke Alarm” for details. Do not connect it to any other type of alarm or auxiliary device. Connecting anything else to this unit may damage it or prevent it from operating properly.
•The battery compartment resists closing unless a battery is installed. This warns you the unit will not operate under DC power without a battery.
•Do not paint over the unit. Paint may clog the openings to the sensing chamber and prevent the unit from operating properly.
HOW TO INSTALL THIS SMOKE ALARM
This Smoke Alarm is designed to be mounted on any standard wiring junction box to a 4-inch (10 cm) size, on either the ceiling or wall. Read “Recommended Locations For Smoke Alarms” and “Locations to Avoid For Smoke Alarms” before you begin installation.
Tools you will need: • Needle-nose pliers or utility knife • Standard Flathead screwdriver.
Make sure the Alarm is not receiving excessively noisy power. Examples of noisy power could be major appliances on the same circuit, power from a generator or solar power, light dimmer on the same circuit or mounted near fluorescent lighting. Excessively noisy power may cause damage to your Alarm.
THE PARTS OF THIS SMOKE ALARM
The Mounting Bracket:
To remove the mounting bracket from the Smoke Alarm base, hold the Smoke Alarm base firmly and twist the mounting bracket counterclockwise.
The mounting bracket installs onto the junction box. It has a variety of screw slots to fit most boxes.
The Power Connector:
The power connector plugs into a power input block on the Smoke Alarm. It supplies the unit with AC power.
•The black wire is “hot.”
•The white wire is neutral.
•The orange wire is used for interconnect.
If you need to remove the power connector, insert a flat screwdriver blade between the power connector and the security tab inside the power input block.
Gently pry back the tab and pull the connector free.

FOLLOW THESE INSTALLATION STEPS
The basic installation of this Smoke Alarm is similar whether you want to install one Smoke Alarm, or interconnect more than one Smoke Alarm. If you are interconnecting more than one Smoke Alarm, you MUST read “Special Requirements For Interconnected Smoke Alarms” below before you begin installation.
ELECTRICAL SHOCK HAZARD. Turn off power to the area where you will install this unit at the circuit breaker or fuse box before beginning installation. Failure to turn off the power before installation may result in serious electrical shock, injury or death.
1. Using wire nuts, connect the power connector to the household wiring.
Improper wiring of the power connector or the wiring leading to the power connector will cause damage to the Alarm and may lead to a non-functioning Alarm.
STAND-ALONE ALARM ONLY:
•Connect the white wire on the power connector to the neutral wire in the junction box.
•Connect the black wire on the power connector to the hot wire in the junction box.
•Tuck the orange wire inside the junction box. It is used for interconnect only.
INTERCONNECTED UNITS ONLY:
Strip off about 1/2” (12 mm) of the plastic coating on the orange wire on the power connector.
•Connect the white wire on the power connector to the neutral wire in the junction box.
•Connect the black wire on the power connector to the hot wire in the junction box.
•Connect the orange wire on the power connector to the interconnect wire in the junction box. Repeat for each unit you are interconnecting. Never connect the hot or neutral wires in the junction box to the orange interconnect wire. Never cross hot and neutral wires between Alarms.
2.Remove the mounting bracket from the base, and attach it to the junction box.
3.Plug the power connector into the back of the Smoke Alarm.
4.Position the base of the Smoke Alarm over the mounting bracket and turn. The Alarm will remain secure over a wide rotation range to allow for perfect alignment. When wall mounting, this will allow fine-tuning on the positioning to compensate for misaligned wall studs and to keep the wording level. The Alarm can be positioned over the bracket every 120°. Rotate the Alarm until aligned properly.
5.Check all connections.
STAND-ALONE ALARM ONLY:
•If you are only installing one Smoke Alarm, restore power to the junction box.
INTERCONNECTED UNITS ONLY:
•If you are interconnecting multiple Smoke Alarms, repeat steps 1-5 for each Smoke Alarm in the series. When you are finished, restore power to the junction box.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Smoke Alarms are completely installed. Restoring power before installation is complete may result in serious electrical shock, injury or death.
6.Make sure the Smoke Alarm is receiving AC power. Under normal operation, the Green power indicator light will shine continuously.
7.If the Green power indicator light does not light, TURN OFF POWER TO THE JUNCTION BOX and recheck all connections. If all connections are correct and the Green power indicator still does not light when you restore the power, the unit should be replaced immediately.
8.Single Station Alarms: Test each Smoke Alarm. Press and hold the Test/Silence button until the unit alarms.
Interconnected Alarms: Press and hold the Test/Silence button until the unit alarms. All interconnected Alarms should sound. The other Alarms sounding only tests the interconnect signal between Alarms. It does not test each Alarm’s operation. You must test each Alarm individually to check if the Alarm is functioning properly.
If any unit in the series does not alarm, TURN OFF POWER and recheck connections. If it does not alarm when you restore power, replace it immediately.
9.For new construction, place supplied dust cover over Alarm to prevent damage from dust and construction debris. When construction is complete, remove cover.
Smoke will not be able to reach smoke sensor while cover is in place. Cover must be removed!
SPECIAL REQUIREMENTS FOR INTERCONNECTED SMOKE ALARMS
•Failure to meet any of the above requirements could damage the units and cause them to malfunction, removing your protection.
•AC and AC/DC Smoke Alarms can be interconnected. Under AC power, all units will alarm when one senses smoke. When power is interrupted, only the AC/DC units in the series will continue to send and receive signals. AC powered Smoke Alarms will not operate.
Interconnected units can provide earlier warning of fire than stand-alone units, especially if a fire starts in a remote area of the dwelling. If any unit in the series senses smoke, all units will alarm. To determine which Smoke Alarm initiated an alarm, see table:
During an Alarm:
On Initiating Alarm(s) |
Red LED(s) flashes (flash) rapidly |
On All Other Alarms |
Red LED is Off |
|
|
After an Alarm (Latching): |
|
|
|
On Initiating Alarm(s) |
Green LED(s) On for 2 seconds/Off for 2 seconds |
|
|
On All Other Alarms |
Green LED(s) On, Red LED(s) is Off |
|
|
