IMPORTANT! READ BEFORE INSTALLING SMOKE ALARM
Read “Where To Install Smoke Alarms” and “Where Not To Install 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.
HOW TO INSTALL THIS SMOKE ALARM
This unit is designed to be mounted on any standard wiring junction box up to a 4-inch diagonal size, on either the ceiling
or wall (if allowed by local electrical codes). Read “Where to Install Smoke Alarms” and “Where Not To Install Smoke
Alarms” before you begin installation.
Tools you will need: Standard/Flathead screwdriver.
Installing This Smoke Alarm:
The basic installation of this smoke alarm is the 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.
1. Hold the unit’s base firmly and twist the mounting bracket counterclockwise (left) to separate it from the unit. Install the
mounting bracket onto the junction box. Use the screw slots on the bracket that fit the junction box you are using.
2.
Activate the battery back-up.
Slide battery door toward
the center of the alarm. Remove the battery and
reposition it as shown on the label inside the battery
compartment. Slide battery door back into place to cover
the battery.
Test the battery back-up.
Press and hold the test
button on the unit's cover until the alarm sounds. If it
does not alarm, retest it with a fresh battery. If it still
does not alarm, replace it immediately.
3. Place foam gasket against the back of unit. Line up the cut-outs with the power input block. It will only fit one way.
IMPORTANT!
You must install the foam gasket supplied to ensure proper operation and to comply with UL standards.
4. Using wire nuts, connect the power connector to the household wiring.
5. Plug the power connector into the back of the smoke alarm.
6. Line up the alignment tab on the base with the alignment tab on the mounting bracket. Turn the smoke alarm clockwise
(right) until you hear the unit snap into place.
7. Check all connections.
8. Make sure the smoke alarm is receiving AC power. Under normal operation, the green power indicator light will shine
continuously. If the power indicator light does not light, TURN OFF POWER TO THE JUNCTION BOX and recheck all
connections. If all connections are correct and the power indicator still does not light when you restore the power, the unit
should be replaced immediately.
9. Test the smoke alarm. Press and hold the test button on the cover of the unit until the alarm sounds (the unit may continue
to alarm for a few seconds after you release the button).
During testing, you will hear a loud, repeating horn pattern:
3 beeps, pause, 3 beeps, pause.
In an interconnected series, you must test each smoke alarm individually.
IMPORTANT!
If any smoke alarm does not alarm, TURN OFF POWER and recheck connections. If any smoke alarm still does not alarm
when you test it after restoring power, replace it immediately.
Special Requirements For Interconnected Smoke Alarms
Interconnected units can provide earlier warning of fire than stand-alone units, especially if a fire starts in a remote area of the
home. If any unit in the series senses smoke, all units will alarm. This unit can be interconnected with

IMPORTANT!
Interconnect units within a single family residence only. Otherwise all households will experience unwanted alarms when you test
any unit in the series. Interconnected units will only work if they are wired to compatible units and all requirements are met.
Interconnected units must meet ALL of the following requirements:
•A maximum of 18 units total may be interconnected (Maximum of 12 smoke alarms).
• The same fuse or circuit breaker must power all interconnected smoke alarms.
• The total length of wire interconnecting the units should be less than 1000 feet (300 meters). The interconnect wire
should be #18 gauge or larger, rated at least 300V. If an interconnect wire is not already part of your household wiring,
you will need to install one. This type of wire is commonly available at Hardware and Electrical Supply stores.
• All wiring must conform to all local electrical codes and Article 760 of the National Electrical Code (NFPA 70).
Refer to NFPA 72, Chapter 2 and/or your local building code for further connection requirements.
WEEKLY TESTING
It is important to test this unit every week to make sure it is working properly. Using the test button is the
recommended way to test this smoke alarm.
Press and hold the test button on the cover of the unit until the alarm sounds
(the unit may continue to alarm for a few seconds after you release the button). If it does not alarm, make sure the unit is receiving
power and test it again. If it still does not alarm, replace it immediately.
During testing, you will hear a loud, repeating horn
pattern: 3 beeps, pause, 3 beeps, pause. When testing a series of interconnected units you must test each unit
individually. Make sure all units alarm when each one is tested.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there are a few simple things you must do to keep it
working properly.
•Test it at least once a week.
• Clean the smoke alarm at least once a month; gently vacuum off any dust using your household vacuum’s soft brush
attachment.
Never use water, cleaners or solvents since they may damage the unit.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where To Install Smoke Alarms.”
• When the battery back-up becomes weak, the smoke alarm unit will “chirp” about once a minute (the low
battery warning). This low battery warning should last for 7 days, but you should replace the battery immediately to
continue your protection.
Choosing a replacement battery:
Your smoke alarm’s battery back-up requires one standard 9V battery. The following batteries are acceptable as replacements:
Eveready
#216, #522 (Energizer), #1222
; Duracell #MN1604; Gold Peak #1604P, #1604S; Rayovac 1604, D1604. These
batteries are available at many local retail stores. You may also use a Lithium battery like the Ultralife U9VL-J for longer service
life between battery changes. These batteries are available at many local retail stores.
Most carbon zinc batteries have an average service life of 1 year; most alkaline batteries have an average service life of 1-2
years; most Lithium batteries have an average service life of 6-10 years. Actual service life depends on the smoke alarm and the
environment in which it is installed. All the batteries specified above are acceptable replacement batteries for this unit.
Regardless of the manufacturer’s suggested battery life, you MUST replace the battery immediately once the unit starts
“chirping” (the “low battery warning”).
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 absolutely certain of the source of the smoke, get everyone out of the house immediately.
Stay calm and follow your family escape plan. Stay as low to the ground as possible, and cover your mouth with a damp cloth.
Never open a door before testing to see if it is hot. Call the Fire Department from outside, and give them your address then
name. Read “What To Do In Case Of Fire” at the end of this manual for more information.
If the unit alarms and you are certain that the source of smoke is not a fire—cooking smoke or an extremely dusty furnace—
open a nearby window or door and fan the smoke away from the unit. This will silence the alarm, and once the smoke clears the
unit will reset itself automatically.
IF YOUR SMOKE ALARM IS NOT WORKING PROPERLY
If this unit is not working properly, there are a few simple things you should check before returning or replacing the unit:
• Make sure it is clean as described in “Regular Maintenance.” A build-up of dirt, dust or grease can affect the unit’s
performance.
• Make sure the unit is installed in a proper location. If you experience frequent unwanted alarms, try relocating it.
See “Where to Install Smoke Alarms” for details.
• Make sure it is receiving AC power from the household current.
• Check that the back-up battery is fresh and still providing back-up protection.
CAUTION!
Always discharge the branch circuit before servicing an AC or AC/DC smoke alarm. First, turn off the AC power at
the circuit breaker or fuse box. Next, remove the battery from smoke alarms with battery back-up. Finally, press
and hold the test button for 5-10 seconds to discharge the branch circuit.

DANGER!
• 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.
WARNING!
• 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; Article 760 of the National
Electrical Code (NFPA 70), NFPA 72, 101; 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, 120VAC 60Hz 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.
• This 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 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.
• It is possible an electrical fire could occur on the circuit powering this unit. If this happened, the power to
the unit could be cut off and it may fail to alarm. Some safety experts recommend wiring warning devices
like this unit on separate circuits from other appliances, since these circuits are not as likely to be over-
loaded. Other safety experts recommend wiring these units on the same circuits as appliances so it is
more readily apparent if the circuit fails. Whichever circuit you choose, it is recommended you also install
battery powered units as back-ups in case of fire on the circuit powering the AC powered units.
• 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.
CAUTION!
• 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.
• Do not stand too close to the unit when the alarm is sounding. It is loud to wake you in an emergency.
Exposure to the horn at close range may harm your hearing. When testing the unit, step back when the
horn starts sounding.
• Do not paint over the unit. Paint may clog the openings to the sensing chamber and prevent the unit from
operating properly.
• The battery was shipped “backwards” to keep it fresh. The unit cannot receive battery back-up power
until you remove the battery and reposition it properly.
• This unit has a “missing battery” tab that prevents it from attaching to the mounting bracket unless a
battery is installed. This warns you the battery back-up will not operate without a battery.
Important Installation Parts
The Mounting Bracket
The Foam Gasket
The Power Connector
The mounting bracket installs onto
the junction box. It has a variety of
screw slots to fit most boxes. If a
junction box is not already in place,
install one using standard #12 or #14
gauge copper wire. To remove the
mounting bracket from the smoke
alarm base, hold the smoke alarm
base firmly and twist the mounting
bracket counterclockwise.
The foam gasket prevents air
currents from coming through
the junction box and blowing
smoke away from the sensor. It
must be installed to comply with
UL standards. When installing
the foam gasket, line up the cut-
outs with the power input block
on the smoke alarm.
• The black wire is “hot.”
• The white wire is neutral.
• The orange wire is 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.
The power connector plugs into a
power input block on the smoke alarm.
It supplies the unit with AC power.
