1. Smoke Alarm: What To Do When The Alarm Sounds
The smoke alarm pattern is three long beeps with voice “Fire!,” a 1.5 second pause, and three long beeps repeating.
The red LED blinks in time with the alarm pattern.
•Alert small children in the home as well as anyone else that might have difficulty recognizing the impor-
tance of the alarm sounding or that might have difficulty leaving the area without help.
•Leave immediately by your escape plan. Every second counts, so don’t waste time getting dressed or
picking up valuables.
•While leaving, don’t open any inside door without first feeling its surface. If hot, or if you see smoke seeping
through cracks, don’t open that door! Instead, use your alternate exit. If the inside of the door is cool, place
your shoulder against it, open it slightly and be ready to slam it shut if heat and smoke rush in.
•If the escape route requires you to go through smoke, stay close to the floor where the air is cleaner. Crawl
if necessary, and breathe shallowly through a cloth, wet if possible.
•Once outside, go to your selected meeting place and make sure everyone is there.
•Call the fire department or 911 from your cell phone outside, or from your neighbor’s home-not from yours!
•Don’t return to your home until the fire officials say that it is all right to do so.
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations

5. Limitations Of Smoke Alarms
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
•Life safety from fire in residential occupancies is based primarily on early notification to occupants of the need to
escape, followed by the appropriate egress actions by those occupants.
•There are situations where a smoke alarm may not be effective to protect against fire as stated in the NFPA Standard
72. For instance:
a) smoking in bed
b) leaving children home alone
c) cleaning with flammable liquids, such as gasoline
•Fire warning systems for dwelling units are capable of protecting about half of the occupants in potentially fatal
fires. A smoke alarm may not be effective in some situations, such as during incendiary fires where the fire grows
so rapidly that an occupant’s egress is blocked even with properly located smoke alarms, or when victims are inti-
mate with the fire (for example, when a person’s clothes catch fire while cooking), too old or young, or physically or
mentally impaired such that they cannot escape even when warned early enough that escape should be possible.
For these people, additional strategies such as protection-in-place or assisted escape or rescue are necessary.
•For maximum detection of the various types of fires that can occur within the home, including fast flaming, slow
smoldering, and polyurethane foam, it is recommended that multi criteria smoke alarms be installed. This model
meets the new polyurethane foam fire detection requirements, while at the same time includes intelligent
technology to reduce nuisance alarms from cooking.
•A battery powered alarm must have a battery of the specified type, in good condition and installed properly (this
model has a replaceable 9V battery).
•Smoke alarms must be tested regularly to make sure the battery and the alarm circuits are in good operating
condition.
•Smoke alarms cannot provide an alarm if smoke does not reach the alarm. Therefore, smoke alarms may not sense
fires starting in chimneys, within walls, on roofs, on the other side of a closed door or other obstruction.
•If the alarm is located outside the bedroom or on a different floor, it may not wake up a sound sleeper.
•The use of alcohol or drugs may also impair one’s ability to hear the smoke alarm. For maximum protection, a
smoke alarm should be installed in each sleeping area on every level of a home.
This alarm is not intended to alert hearing impaired individuals.

9
6. Recommended Locations For Smoke Alarms
•Locate smoke alarms in all sleeping areas. Try to monitor the exit path as the bedrooms are usually farthest
from the exit. If more than one sleeping area exists, locate additional alarms in each sleeping area.
•Locate additional alarms in stairways, because stairways act like chimneys for smoke and heat.
•Locate at least one alarm on every floor level.
•Locate an alarm in every bedroom.
•Locate an alarm in every room where electrical appliances are operated (i.e. portable heaters or humidifiers).
•Locate an alarm in every room where someone sleeps with the door closed. The closed door may prevent
an alarm not located in that room from waking the sleeper.
•Smoke, heat, and combustion products rise to the ceiling and spread horizontally. Mounting the smoke
alarm on the ceiling in the center of the room places it closest to all points in the room. Ceiling mounting is
preferred in ordinary residential construction.

NFPA 72 states: “Smoke alarms in rooms with ceiling slopes greater than 1 ft in 8 ft (.3m in 2.4 m) horizontally
shall be located on the high side of the room.” NFPA 72 states: “A row of detectors shall be spaced and located
within 3 ft (0.9m) of the peak of the ceiling measured horizontally.”
Figure 6-B Figure 6-C

•For mobile home installation, select locations carefully to avoid thermal barriers that may form at the
ceiling. For more details, see MOBILE HOME INSTALLATION section.
•When mounting an alarm on the ceiling, locate it at a minimum of 4” (10 cm) from the side wall.
•When mounting the alarm on the wall, use an inside wall with the top edge of the alarm at a minimum of 4”
(10 cm) and a maximum of 12” (30.5 cm) below the ceiling.
•Put smoke alarms at both ends of a bedroom hallway or large room if the hallway or room is more than 30
feet (9.1 m) long.
•Install Smoke Alarms on sloped, peaked or cathedral ceilings at or within 3ft (0.9m) of the highest point
(measured horizontally).
This equipment should be installed in accordance with the National Fire Protection Association’s 72 (National
Fire Protection Association, Batterymarch Park, Quincy, MA 02269).
Mobile Home Installation
Modern mobile homes have been designed and built to be energy efficient. Install smoke alarms as recom-
mended above. In older mobile homes that are not well insulated compared to present standards, extreme
heat or cold can be transferred from the outside to the inside through poorly insulated walls and roof. This may
create a thermal barrier which can prevent the smoke from reaching an alarm mounted on the ceiling. In such
units, install the smoke alarm on an inside wall with the top edge of the alarm a minimum of 4” (10 cm) and a
maximum of 12” (30.5 cm) below the ceiling.
If you are not sure about the insulation in your mobile home, or if you notice that the outer walls and ceiling are
either hot or cold compared to the room air temperature, install the alarm on an inside wall. NFPA 72 (National
Fire Protection Association) requires smoke alarms be installed in each sleeping area.
WARNING: TEST YOUR ALARM OPERATION AFTER MOBILE HOME HAS BEEN IN STORAGE OR
UNOCCUPIED, AND AT LEAST ONCE A WEEK DURING USE.

7. Locations To Avoid
(See Figures 6-A, 6-B, & 6-C)
•In the garage. Products of combustion are present when you start your automobile.
•Normal cooking may cause nuisance alarms. If a kitchen alarm is desired, it should have an alarm silence
feature and should not be installed within 6 ft of cooking appliances.
•Do not install within 6 ft of heating appliances.
•Less than 4” (10cm) from the peak of an “A” frame type ceiling.
•In an area where the temperature may fall below 40ºF or rise above 100ºF, such as garages and unfinished
attics.
•In dusty areas. Dust particles may cause nuisance alarms or a failure to alarm.
•In very humid areas (above 95% RH, non-condensing) as moisture or steam can cause nuisance alarms.
•In insect-infested areas.
•Smoke alarms should not be installed within 3 ft (.9m) of the door to a bathroom containing a tub or
shower, forced air supply ducts used for heating or cooling, ceiling or whole house ventilating fans, or other
high air flow areas.
•Near lights. Electronic “noise” generated by the lights may cause nuisance alarms.
•Do not install near vents, flues, or chimneys.
•Do not install near fans, doors, windows or areas directly exposed to the weather.
NOTE : Smoke alarms are not to be used with detector guards unless the combination (alarm and detector
guard) has been evaluated and found suitable for that purpose.

8. Installation And Activation
After selecting the proper location for your
alarm, attach the mounting bracket to the wall
or ceiling. To ensure aesthetic alignment of
the alarm with the hallway, or wall, the “A” line
on the mounting bracket should be parallel
with the hallway when ceiling mounted, or
horizontal when wall mounted.
(Figure 8-A)
•Install the alarm fully on the mounting
bracket by rotating the alarm in a clockwise
direction. (Figure 8-B)
NOTE : The alarm will mount to the bracket
in 4 positions (every 90 degrees).
•Pull out the battery pull tab to activate the
battery.(Figure 8-C)
•Battery activation is confirmed with a single
power-on chirp, and a voice prompt to “Push
Test Button.”
•If pulling the battery tab does not result in
the chirp and voice notifications, open and
close the battery compartment once.
Confirm power activation.
•The alarm is now activated! After
installation / activation, test your alarm as
described in Operation and Testing section.

Tamper Resist Features
To make your alarm tamper resistant, two tamper resist features have been provided. The first is used to discour-
age removal of the alarm while the second is for the battery.
Smoke Alarm Tamper Resist
To activate the mounting bracket tamper resist feature break off the four posts in the square holes in the trim
ring (see figure 8-D). When the posts are broken off, the tamper resist tab on the base is allowed to engage the
mounting bracket. Rotate the alarm onto the mounting bracket until you hear the tamper resist tab snap into
place, locking the alarm on the mounting bracket. Using the tamper resist feature will help deter children and
others from removing the alarm from the mounting bracket.
NOTE: To remove the alarm when the tamper resist tab is engaged, press down on the tamper resist tab, and
rotate the alarm off of the bracket (see Figure 8-E).
Battery Carrier Tamper Resist
This alarm also has a battery carrier tamper resist feature, which helps prevent the battery carrier from being
opened.This feature is effective in preventing the removal of the battery from this device.
POSTS
Figure 8-D
Figure 8-E

15
To activate the battery carrier tamper resist feature, remove the unit from
the mounting bracket, and locate the small cut-out in the middle of the
label on the back of the unit. With a small screwdriver, or similar tool, slide
the switch towards the the “LOCK” position as shown on the label (see
Figure 8-F). The tamper resist feature is now active and the battery carrier
can not be opened until the tamper resist feature is deactivated.
NOTE: Before activating the battery carrier tamper resist feature, make sure
a fresh battery is installed in the unit and that the battery carrier is properly
closed. If the battery carrier tamper resist feature is activated while the
battery carrier is open, the battery carrier will not close and the unit will be inoperable.
To deactivate the battery carrier tamper resist, in order to change the smoke alarm battery, remove the unit
from the mounting bracket (see Smoke Alarm Tamper Resist Feature if activated), and locate the small cut-out in
the middle of the back label. Using a screwdriver, or similar tool, slide the switch in the opposite direction of the
“LOCK” arrow as shown on the label. The battery carrier can now be opened and the battery changed.

9. Operation And Testing
Operation
The alarm is operating once it is activated and testing is complete (see “TESTING” below). When products of
combustion (smoke) are sensed, the unit sounds a loud alarm with voice messages. See Section 1 for alarm
signal descriptions.
Testing
Test your alarm weekly by pressing and releasing the test button quickly. A quick beep will confirm the button
has been pushed followed by the test sequence. See Other Alarm Visual and Audible Indicators table. The alarm
and voice will sound if the electronic circuitry, horn, speaker, and battery are working. If the alarm or voice does
not sound, or gives erratic or low volume sound, the unit must be replaced.
WARNING: DUE TO THE LOUDNESS OF THE ALARM, ALWAYS STAND ABOUT 2.5 FEET AWAY
FROM THE UNIT OR USE EAR PROTECTION WHEN TESTING.
WARNING: DO NOT USE AN OPEN FLAME TO TEST YOUR ALARM, YOU COULD DAMAGE THE
ALARM OR IGNITE COMBUSTIBLE MATERIALS AND START A STRUCTURE FIRE.
Chirping
When End of Unit Life or Low Battery chirping begins, you can temporarily silence these chirps by pressing
the Test/Hush® button. See Troubleshooting Guide.
WARNING: REPLACE UNIT AS SOON AS POSSIBLE WHEN IN END OF UNIT LIFE MODE.

10. Recognizing Nuisance Alarms
Smoke Nuisance
HUSH®: If you know why the alarm is sounding, and you can verify that it is not a life threatening situation,
you can push the button silence the alarm for 8-10 minutes. If the smoke is not too dense, that unit will silence.
After the Hush® period, the smoke alarm will automatically reset and sound the alarm if particles of combus-
tion are still present. You can use Hush® repeatedly until the air has been cleared of the condition causing the
alarm.
NOTE: Dense smoke will override Hush® and sound a continuous alarm. If no fire is present, check to
see if one of the reasons listed in “Locations to avoid” may have caused the alarm. If a fire is
discovered, get out and call the fire department or 911.
This alarm is designed to minimize nuisance alarms. Cigarette smoke will not normally cause the unit to alarm,
unless the smoke is blown directly into the alarm. Combustion particles from cooking may set off the alarm
if it is located too close to a cooking appliance. Large quantities of combustible particles are generated from
spills or when broiling. Using the fan on a range hood which vents to the outside (non-recirculating type) will
also help prevent nuisance alarms from occurring by removing these combustible products from the kitchen.

18
11. Bat t er y
This alarm is powered by a a replaceable 9V battery located in a convenient front load battery compartment.
Under normal conditions, a fresh battery should last at least one year.
NOTE: Constant exposure to high or low humidity or temperatures may reduce battery life.
WARNING: THE ALARM IS SEALED AND THE COVER IS NOT REMOVABLE!
Low Battery
This alarm is equipped with a low battery monitor circuit. If the battery capacity is nearing the point where it
can no longer provide adequate power for all alarm functions, the low battery condition will occur. See Trouble-
shooting Guide. The battery must be replaced within 7 days of the first occurrence of the “Low Battery Warning”
to provide continuous alarm protection.
NOTE: If the battery carrier tamper resist feature has been activated it will need to be deactivated in order to
change the battery. Refer to section “Tamper Resist Features” for instructions.
To replace or install the battery press on the battery carrier and then release to allow the carrier to pop open.
The battery can then be pulled out of the carrier. When installing a new battery into the carrier, make sure
the battery terminals are exposed and that the polarity matches the markings printed on the battery carrier.
Completely press the battery carrier down into the alarm and release, the battery carrier will lock into the closed
position. A missing or improperly installed battery will prevent the battery carrier from closing and render the
unit inoperable.
Replace battery with one of the following approved brands:
Duracell MN1604, MX1604, Energizer 522 and Gold Peak 1604A.
These batteries can be purchased at your local retailer.
WARNING: Use only the batteries specified. Use of different batteries may have a detrimental effect on the alarm.
NOTE: Do not use lithium batteries in this unit. A good safety measure is to replace the battery at least once a year, or at the
same time you change your clocks for daylight saving time.

19
12. Cleaning Your Alarm
Your Alarm Should be Cleaned at Least Once a Year
You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum cleaner hose
and blowing or vacuuming through the openings around the perimeter of the alarm. The outside of the alarm
can be wiped with a damp cloth. Use only water to dampen the cloth, use of detergents or cleaners could
damage the alarm.
If the tamper resist feature has been activated, refer to tamper resist feature description in section 8 for removal
instructions. Remove the alarm from the mounting bracket by rotating the alarm in the direction of the “off”
arrow on the cover.
If the alarm is in Fault mode, the alarm may be in need of cleaning. After cleaning, press the Test/Hush® button.
If the fault does not clear, the alarm needs to be replaced.
•Never use detergent or other solvents to clean the unit.
•Avoid spraying air freshener, hair spray, or other aerosols near the alarm.
•Do not paint the unit. Paint will seal the vents and interfere with the sensor’s ability to detect smoke.
•Never attempt to disassemble the unit or clean inside. This action will void your warranty.
WARNING: REINSTALL THE ALARM AS SOON AS POSSIBLE TO ENSURE CONTINUOUS
PROTECTION.

20
13. Good Safety Habits
Develop and Practice a Plan of Escape
Prepare and practice a home escape plan twice a year, including drills at night. Know two ways out of every
room (door & window) and identify a meeting place outside the home where everyone will gather once they
have exited the residence. When two people have reached the meeting place, one should leave to call 911
while the second person stays to account for additional family members. Establish a rule that once you’re out,
you never re-enter under any circumstance!
•Make a floor plan indicating all doors and windows and at least two (2) escape routes from each room.
Stories above ground level may need a rope or chain ladder.
•Have a family meeting and discuss your escape plan, showing everyone what to do in case of fire and
where to meet after they leave the house.
•Ensure that small children hear the alarm and wake when it sounds. They must wake up in order to execute
the escape plan. Practice allows all occupants to test your plan before an emergency. You may not be able
to reach your children. It is important they know what to do.
•Familiarize everyone with the sounds of the smoke alarm and train them to leave your home when they
hear it.
•Current studies have shown smoke alarms may not awaken all sleeping individuals, and that it is the
responsibility of individuals in the household that are capable of assisting others to provide assistance to
those who may not be awakened by the alarm sound, or to those who may be incapable of safely evacuat-
ing the area unassisted.
•Install and maintain fire extinguishers on every level of the home and in the kitchen, basement and garage.
Know how to use a fire extinguisher prior to an emergency.
