1. RECOMMENDED LOCATIONS FOR ALARMS
• Locate the first alarm in the imme iate area of the be rooms. Try to monitor
the exit path as the be rooms are usually farthest from the exit. If more than
one sleeping area exists, locate a itional alarms in each sleeping area.
• Locate a itional alarms to monitor any stairway as stairways act like chim-
neys for smoke an heat.
!

FIGURE 1
FIGURE 2 FIGURE 3
• Locate at least one alarm on every floor level.
• Locate an alarm in every sleeping room.
• Locate an alarm in every room where electrical appliances are operate (i.e.
portable heaters or humi ifiers).
• Locate an alarm in every room where someone sleeps with the oor close .
The close oor may prevent an alarm not locate in that room from waking
the sleeper.
• Smoke, heat, an combustion pro ucts rise to the ceiling an sprea horizon-
tally. 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 preferre in
or inary resi ential construction.
• For mobile home installation, select locations carefully to avoi thermal
barriers that may form at the ceiling. For more etails, see MOBILE HOME
INSTALLATION.
• When mounting an alarm on the ceiling, locate it at a minimum of 4” (10 cm)
from the si e wall (see figure 1).
• When mounting the alarm on the wall, use an insi e wall with the top e ge
of the alarm at a minimum of 4” (10 cm) an a maximum of 12” (30.5 cm)
below the ceiling (see figure 1).
• Put smoke alarms at both en s of a be room hallway or large room if the
hallway or room is more than 30 ft (9.1 m) long.
1220-7208-02_EN_V2a.qxd:_ 2015.12.4 10:19 AM Page 3

• Install Smoke Alarms on slope , peake or cathe ral ceilings at or within 3ft
(0.9m) of the highest point (measure horizontally). NFPA 72 states: “Smoke
alarms in rooms with ceiling slopes greater than 1 ft in 8 ft (.3m in 2.4 m) hor-
izontally shall be locate on the high si e of the room.” NFPA 72 states: “A
row of etectors shall be space an locate within 3 ft (0.9m) of the peak of
the ceiling measure horizontally” (see figure 3).
MOBILE HOME INSTALLATION
Mo ern mobile homes have been esigne an built to be energy efficient.
Install smoke alarms as recommen e above (refer to RECOMMENDED LOCA-
TIONS an figures 1 an 2).
In ol er mobile homes that are not well insulate compare to present stan-
ar s, extreme heat or col can be transferre from the outsi e to the insi e
through poorly insulate walls an roof. This may create a thermal barrier
which can prevent the smoke from reaching an alarm mounte on the ceiling.
In such units, install the smoke alarm on an insi e wall with the top e ge of the
alarm at a minimum of 4” (10 cm) an a maximum of 12” (30.5 cm) below the
ceiling (see figure 1).
If you are not sure about the insulation in your mobile home, or if you notice
that the outer walls an ceiling are either hot or col , install the alarm on an
insi e wall. For minimum protection, install at least one alarm close to the be -
rooms. For a itional protection, see SINGLE FLOOR PLAN in figure 2.
WARNING: TEST YOUR SMOKE ALARM OPERATION AFTER MOBILE
HOME VEHICLE HAS BEEN IN STORAGE AND AT LEAST ONCE A WEEK
DURING USE.
2. LOCATIONS TO AVOID
• In the garage. Pro ucts of combustion are present when you start your auto-
mobile.
• Less than 4” (10cm) from the peak of an “A” frame type ceiling.
• In an area where the temperature may fall below 40ºF (4.4˚C) or rise above
100ºF (37.8˚C), such as garages an unfinishe attics.
• In usty areas. Dust particles may cause nuisance alarm or failure to alarm.
• In very humi areas (Greater than 95% RH, non-con ensing). Moisture or
steam can cause nuisance alarms.
• In insect-infeste areas.
• Smoke alarms shoul not be installe within 3 ft (.9m) of the following: the
!

oor to a kitchen, the oor to a bathroom containing a tub or shower, force
air supply ucts use for heating or cooling, ceiling or whole house ventilating
fans, or other high air flow areas.
• Kitchens. Normal cooking may cause nuisance alarms. If a kitchen alarm is
esire , it shoul have an alarm silence feature or be a photoelectric type.
• Near fluorescent lights. Electronic “noise” may cause nuisance alarms.
• Smoke alarms are not to be use with etector guar s unless the combination
(alarm an guar ) has been evaluate an foun suitable for that purpose.
3. INSTALLATION INSTRUCTIONS
WIRING REQUIREMENTS
• This smoke alarm shoul be installe on a U.L. liste or recognize junction
box. All connections shoul be ma e by a qualifie electrician an all wiring
use shall be in accor ance with articles 210 an 300.3(B) of the U.S. National
Electrical Co e ANSI/NFPA 70, NFPA 72 an /or any other co es having juris ic-
tion in your area. The multiple station interconnect wiring to the alarms must
be run in the same raceway or cable as the AC power wiring. In a ition, the
resistance of the interconnect wiring shall be a maximum of 10 ohms.
• The appropriate power source is 120 Volt AC Single Phase supplie from a
non-switchable circuit which is not protecte by a groun fault interrupter.
• WARNING: This alarm cannot be operate from power erive from a square
wave, mo ifie square wave or mo ifie sine wave inverters. These types of
inverters are sometimes use to supply power to the structure in off gri
installations, such as solar or win erive power sources. These power
sources pro uce high peak voltages that will amage the alarm.
WIRING INSTRUCTIONS FOR AC QUICK CONNECT HARNESS
CAUTION! TURN OFF THE MAIN POWER TO THE CIRCUIT BEFORE
WIRING THE ALARM.
• For alarms that are use as single station, DO NOT CONNECT THE RED WIRE
TO ANYTHING. Leave the re wire insulating cap in place to make certain that
the re wire cannot contact any metal parts or the electrical box.
• When alarms are interconnecte , all interconnecte units must be powere
from a single circuit.
• A maximum of 24 Ki e evices may be interconnecte in a multiple station
arrangement. The interconnect system shoul not excee the NFPA intercon-
nect limit of 12 smoke alarms an /or 18 alarms total (smoke, heat, carbon
monoxi e, etc.). With 18 alarms interconnecte , it is still possible to intercon-

TAMPER RESIST LOCKING PIN: To make your smoke alarm tamper resistant, a
locking pin has been provi e with your alarm. Using this pin will help eter
chil ren an others from removing the alarm from trim ring. To use the pin,
insert it into the hole in the si e of the alarm after the alarm has been installe
on the trim ring (see figure 8). NOTE: The tamper resist pin will have to be
remove in or er to change the batteries. Use long nose pliers to pull the pin
out of the hole. It is now possible to remove the alarm from the trim ring.
After installation, TEST your alarm by pressing an hol ing the test/hush button
for several secon s. This shoul soun the alarm an activate the Safety Light.
4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once AC power is applie , fresh bat-
teries are installe an testing is complete. When the smoke alarm ionization
chamber senses pro ucts of combustion, the horn will soun a lou (85 b)
temporal alarm (an the safety light will activate on mo el i12080A only) until
the sensing chamber is cleare of smoke particles.
HUSHTM CONTROL: The “HUSH” feature has the capability of temporarily esen-
sitizing the alarm circuit for up to 8 minutes. This feature is to be use only
when a known alarm con ition, such as smoke from cooking, activates the
alarm. The smoke alarm is esensitize by pushing the “TEST / HUSH” button
on the smoke alarm cover. If the smoke is not too ense, the alarm will silence
imme iately. The re LED will illuminate for 1.5 secon s every 8-10 secon s
while in hush. This in icates that the alarm is in a temporarily esensitize con-
ition. The smoke alarm will automatically reset after approximately 8 minutes
an soun the alarm if particles of combustion are still present. The “HUSH”
feature can be use repeate ly until the air has been cleare of the con ition
causing the alarm. Pushing the Test / Hush button on the alarm will en the
hush perio .

LED INDICATORS: This smoke alarm is equippe with re an green LED in ica-
tors. The green LED (when illuminate ) in icates the presence of AC power. The
re LED ( locate un er the Test / Hush button) has four mo es of operation:
Standby Condition: The re LED will flash every 40 secon s to in icate
that the smoke alarm is operating properly.
Alarm Condition: When the alarm senses pro ucts of combustion an
goes into alarm, the re LED will flash one flash per
secon . The flashing LED an pulsating alarm will
continue until the air is cleare .
WHEN UNITS ARE INTERCONNECTED, only the re LED
of the alarm which senses the smoke or is being teste
(the originating unit) will flash. All other units in the
interconnect system will soun an alarm but their re
LED’s will NOT be flashing.
Alarm Memory: This smoke alarm is equippe with an alarm memory, which
provi es a visual in ication when an alarm has been activate .
The re LED will illuminate for about 1.5 secon s every 20
secon s to in icate the memory con ition.
The memory will
remain activate until pushing the test button resets it or will
time-out between 11 to 13 hours. In an interconnecte installa-
tion only the memory of the originating alarm will be activate .
Hush®mode: The re LED will illuminate for 1.5 secon s every 10
secon s, in icating the smoke alarm is in the Hush®mo e.

1220-7208-02_EN_V2a.qxd:_ 2015.12.4 10:19 AM Page 9

Testing: Test by pushing the Test/Hush button on the cover an hol
it own for a minimum of 5 secon s. This will soun the
alarm if the electronic circuitry an horn are working. In an
interconnecte installation all interconnecte alarms shoul
soun when the Test/Hush button on any of the
interconnecte alarm is presse . If no alarm soun s, check
the fuse or circuit breaker supplying power to the alarm
circuit. Verify that the green LED is on. If the alarm still oes
not soun , the alarm may have efective batteries or other
failure. DO NOT use an open flame to test your alarm. You
coul amage the alarm or ignite combustible materials an
start a structure fire.
Note: When the alarm soun s the Safety Light on the mo el i12080A will also
illum inate.
TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION. Erratic or low soun
coming from your alarm may in icate a efective alarm, an it shoul be
returne for service (see section 12).
5. NUISANCE ALARMS
Smoke alarms are esigne to minimize nuisance alarms. Cigarette smoke will
not normally set off the alarm, unless the smoke is blown irectly into the alarm.
Combustion particles from cooking may set off the alarm if the alarm is locate
close to the cooking area. Large quantities of combustible particles are generat-
e from spills or when broiling. Using the fan on a range hoo which vents to
the outsi e (non-recirculating type) will also help remove these combustible
pro ucts from the kitchen.
These mo els are equippe with a "Hush" feature that is extremely useful in a
kitchen area or other areas prone to nuisance alarms. For more information,
refer to section 4 OPERATION AND TESTING.
If the alarm oes soun , check for fires first. If a fire is iscovere , get out an
call the fire epartment. If no fire is present, check to see if one of the reasons
liste in section 2 may have cause the alarm.
6. MAINTENANCE / TROUBLESHOOTING

7. LIMITATIONS OF SMOKE ALARMS
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
• NFPA 72 states: Life safety from fire in resi ential occupancies is base primarily
on early notification to occupants of the nee to escape, followe by the
appropriate egress actions by those occupants. Fire warning systems for
welling units are capable of protecting about half of the occupants in poten-
tially fatal fires. Victims are often intimate with the fire, too ol or young, or
physically or mentally impaire such that they cannot escape even when
warne early enough that escape shoul be possible. For these people, other
strategies such as protection-in-place or assiste escape or rescue are necessary.
• Lea ing authorities recommen that both ionization an photoelectric smoke
alarms be installe to help insure maximum etection of the various types of
fires that can occur within the home. Ionization sensing alarms may etect
invisible fire particles (associate with fast flaming fires) sooner than photo-
electric alarms. Photoelectric sensing alarms may etect visible fire particles
(associate with slow smol ering fires) sooner than ionization alarms.
•Abattery powere alarm must have a battery of the specifie type, in goo con-
ition an installe properly.
• AC powere alarms (without battery backup) will not operate if the AC power
has been cut off, such as by an electrical fire or an open fuse.
• Smoke alarms must be teste regularly to make sure the batteries an the
alarm circuits are in goo operating con ition.
• Smoke alarms cannot provi e an alarm if smoke oes not reach the alarm.
Therefore, smoke alarms may not sense fires starting in chimneys, walls, on
roofs, on the other si e of a close oor or on a ifferent floor.
• If the alarm is locate outsi e the be room or on a ifferent floor, it may not
wake up a soun sleeper.
• The use of alcohol or rugs may also impair one’s ability to hear the smoke
alarm. For maximum protection, a smoke alarm shoul be installe in each
sleeping area on every level of a home.
• Although smoke alarms can help save lives by provi ing an early warning of a
fire, they are not a substitute for an insurance policy. Home owners an
renters shoul have a equate insurance to protect their lives an property.
