INTRODUCTION 9000 SERIES  
HOW YOUR SMOKE ALARM WORKS  
The 9000 Series smoke alarm operates on the photoelectric light  
scatter principle. The unit's sensing chamber houses a light source  
and a light sensor.  
The 9123 & 9223 Series smoke alarm is a photoelectric type unit  
for use as an evacuation device in residential and commercial  
residential applications, while the 9120 & 9220 Series are for use as  
an alert and relocate device. Each smoke alarm has a solid state  
piezo signal to warn and alert the household to the presence of  
threatening smoke.  
The darkened sensing chamber is exposed to the atmosphere and  
designed to permit optimum smoke entry from any direction while  
rejecting light from outside the smoke alarm.  
The light source is an infrared (invisible) LED which pulses every 8  
seconds. The light sensor is a photodiode matched to the light  
frequency of the LED light source.  
Under normal conditions, the light generated by the pulsing infrared  
LED is not seen by the light sensor, as it is positioned out of the direct  
path of the light beam. When smoke enters the sensing chamber, light  
from the pulsing LED light source is reflected by the smoke particles  
onto the photodiode light sensor. At the first sighting of smoke, the  
device is put into a pre-alarm mode.  
This is indicated by a rapidly flashing LED on the face of the smoke  
alarm. Once the light sensor confirms smoke for 2 consecutive pulses  
inside the chamber, the light sensor produces the signal necessary to  
trigger the alarm and sound the electronic horn.  
This technique of verifying the smoke condition, combined with a  
5-to-1 signal-to-noise ratio, substantially reduces the possibility of  
nuisance alarms.  
Your photoelectric smoke alarm is designed to detect the smoke  
that results from an actual fire. Consequently, it is uncommon for  
household smoke such as cigarette smoke or normal cooking smoke  
to cause an alarm.  
BASIC SAFETY INFORMATION  
Dangers, Warnings, Cautions and Notices alert you to important  
operating procedures or to potentially hazardous situations. Pay  
special attention to these items.  
WARNING!  
This photoelectric smoke alarm is listed for use in single-family and  
multi-family residences, along with hotels, motels and other  
commercial residential occupancies.  
This photoelectric smoke alarm must receive continuous 120VAC,  
60Hz , pure sine wave electrical power. (battery is meant for  
emergency back-up only). In order for the emergency battery back-up  
to work, a new battery must be properly installed (see BATTERY  
INSTALLATION section).  
NEVER ignore your smoke alarm if it sounds. Refer to IF YOUR  
SMOKE ALARM SOUNDS section for more information. Failure to  
do so can result in serious injury or death.  
Test this device once a week per manufacturer installation  
recommendation. If the device ever fails to test correctly, replace  
immediately! If the device is not working properly, it can not alert you  
to a problem.  
This product is intended for use in indoor locations of family dwelling  
units.  
HOW TO TELL IF YOUR SMOKE ALARM IS  
MODELS  
WORKING PROPERLY  
(SEE BACK OF SMOKE ALARM FOR EXACT MODEL)  
Your smoke alarm is provided with an alarm horn and pulsating  
Light Emitting (indicator) Diode, which pulses every 30 seconds, and  
a green AC power on LED.  
When turning the test knob on the smoke alarm to TEST 1 the red  
light emitting diode should flash rapidly and the horn should sound.  
If the battery is low or missing, a chirp will be emitted when the red  
LED flashes. If the smoke alarm is malfunctioning, the chirp will  
sound between the red LED flashes. If AC power fails, the green  
LED will turn off.  
The test knob of your smoke alarm simulates actual smoke  
conditions.  
NOTE: Tandem Interconnect Models.  
When testing one smoke alarm, the device that is activated will flash  
the red indicator light and sound its alarm horn. All other units will  
sound the alarm horn with their red indicator lights remaining off.  
The relays will also activate on all units in tandem on models  
equipped with the relay option.

29.5.1.1 Where required by applicable laws, codes or standards for a  
specific type of occupancy, approved single and multiple-station smoke  
alarms shall be installed as follows:  
Figure 3  
1) In all sleeping rooms and guest rooms  
2) Outside of each separate dwelling unit sleeping area, within 6.4m  
(21ft) of any door to a sleeping room, the distance measured along a  
path of travel  
Figure 3: IN DWELLING UNITS WITH MORE THAN ONE  
SLEEPING AREA, A SMOKE ALARM SHOULD BE PROVIDED TO  
PROTECT EACH SLEEPING AREA IN ADDITION TO SMOKE  
ALARMS REQUIRED IN BEDROOMS.  
3) On every level of a dwelling unit, including basements  
4) On every level of a residential board and care occupancy (small  
facility), including basements and excluding crawl spaces and  
unfinished attics  
In addition to smoke alarms outside of the sleeping areas and in  
each bedroom, NFPA 72 requires the installation of a smoke alarm on  
each additional level of the dwelling unit, including the basement.  
These installations are shown in Figure 4. The living area smoke  
alarm should be installed in the living room or near the stairway to the  
upper lever, or in both locations. The basement smoke alarm should  
be installed in close proximity to the stairway leading to the floor  
above. Where installed on an open-joisted ceiling, the smoke alarm  
should be placed on the bottom of the joists. The smoke alarm should  
be positioned relative to the stairway so as to intercept smoke coming  
from a fire in the basement before the smoke enters the stairway.  
5) In the living area(s) of a guest suite  
6) In the living area(s) of a residential board and care occupancy  
(small facility)  
29.5.1.2 Where the area addressed in 29.5.1.1(2) is separated from  
the adjacent living areas by a door, a smoke alarm shall be installed in  
the area between the door and the sleeping room, and additional  
alarms shall be installed on the living area side of the door as  
specified by 29.5.1.1 and 29.5.1.3.  
29.5.1.3 In addition to the requirements of 29.5.1.1(1) through  
29.5.1.1(3), where the interior floor area for a given level of a dwelling  
unit, excluding garage areas, is greater than 93m2 (1000ft2), smoke  
alarms shall be installed per 29.5.1.3.1 and 29.5.1.3.2.  
29.5.1.3.1 All points on the ceiling shall have a smoke alarm within a  
distance of 9.1m (30ft) travel distance or shall have an equivalent of  
one smoke alarm per 46.5m2 (500ft2) is evaluated by dividing the total  
interior square footage of floor area per level by 46.5m2 (500ft2).  
29.5.1.3.2 Where dwelling units include great rooms or vaulted/  
cathedral ceilings extending over multiple floors, smoke alarms located  
on the upper floor that are intended to protect the aforementioned area  
shall be permitted to be considered as part of the lower floor(s)  
protection scheme used to meet the requirements of 29.5.1.3.1.  
The installation of additional alarms of smoke, heat or CO type  
should result in a higher degree of protection. Adding alarms to rooms  
that are normally closed off from the required alarms increases the  
escape time because the fire does not need to build to the higher level  
necessary to force smoke out of the closed room to the required  
alarms. As a consequence, it is recommended that the householder  
consider the installation of additional fire protection devices. However,  
it should be understood that NFPA 72 does not require additional  
smoke alarms over and above those called for in Figures 1, 2, 3 and 4  
where required smoke alarms are shown.  
Figure 4  
Figure 4: A SMOKE ALARM SHOULD BE LOCATED ON EACH  
LEVEL IN ADDITION TO EACH BEDROOM.  
Are More Smoke Alarms Desirable? The required number of  
smoke alarms might not provide reliable early warning protection for  
those areas separated by a door from the areas protected by the  
required smoke alarms. For this reason, the use of additional smoke  
alarms for those areas for increased protection is recommended. The  
additional areas include the basement, bedrooms, dining room, fur-  
nace room, utility room, and hallways not protected by the required  
smoke alarms. The installation of smoke alarms in kitchens, attics (fin-  
ished or unfinished), or garages is not normally recommended,  
because these locations occasionally experience conditions that can  
result in improper operation.  
Figure 1  
IMPORTANT CONSIDERATION  
NFPA 72, 2010 Edition, Chapter 29, Section 29.8.1.4(5)(b)  
states: “Smoke alarms installed in one- and two-family dwellings  
shall not remain in service longer than 10 years from the date of  
manufacture.” Smoke alarms should be replaced for the  
following reasons:  
Figure 1: A SMOKE ALARM SHOULD BE LOCATED ON EVERY  
LEVEL OF DWELLING UNIT, INCLUDING BASEMENT, WITHIN  
EACH SLEEPING ROOM AND OUTSIDE SLEEPING AREAS.  
Dust, dirt, and other environmental contaminants can affect your  
smoke alarm over a prolonged period.  
Where to Locate the Required Smoke Alarms. The major threat  
from fire in a dwelling unit occurs at night when everyone is asleep.  
Persons in sleeping areas can be threatened by fires in the remainder  
of the unit; therefore, smoke alarms are best located in each bedroom  
and between the bedroom areas and the rest of the unit as shown in  
Figure 2.  
Fast changing industry consensus standards and codes on all  
smoke alarms make it advisable to periodically upgrade your  
devices to maximize life safety.  
Assurance that your smoke alarm needs are kept abreast with the  
constantly improving electronic technology.  
Smoke alarms are recognized as one of the lowest cost ways to  
protect dwelling inhabitants against the danger of fire(s). It makes  
good common sense to periodically replace and update your  
smoke alarm that contributes so much to life safety.  
Figure 2  
MOUNTING LOCATION  
This smoke alarm can be mounted on a ceiling or wall with equal  
efficiency in either location.  
Ceiling location - smoke alarm should be mounted as close as  
possible to the center of a hallway or room.  
Wall location - locate the top of the smoke alarm not more than 12  
inches from the ceiling.  
Figure 2: A SMOKE ALARM SHOULD BE LOCATED BETWEEN THE  
SLEEPING AREA AND THE REST OF THE DWELLING UNIT AS  
WELL AS IN EACH BEDROOM.

block openings to the sensing chamber and keep the device from  
sensing smoke.  
Figure 5  
Near fresh air inlets, returns or excessively drafty areas. Air  
conditioners, heaters, fans, and fresh air intakes and returns can drive  
smoke away from smoke alarms, making the devices less effective.  
In dead air spaces at the top of a peaked roof or in the corners  
between ceilings and walls. Dead air may prevent smoke from  
reaching a smoke alarm. See Figures 5 and 6 for recommended  
mounting locations.  
In insect-infested areas. If insects enter a smoke alarm's sensing  
chamber, they may cause a nuisance alarm. Get rid of the bugs  
before installing smoke alarms where bugs are a problem.  
Near fluorescent light fixtures. Electrical "noise" from nearby  
fluorescent light fixtures may cause a nuisance alarm. Install smoke  
alarms and fluorescent lights on separate electrical circuits.  
WARNING! Never disconnect an AC smoke alarm to silence a  
nuisance alarm. Open a window or fan the air around the unit to  
remove the smoke. The smoke alarm will automatically turn off when  
the smoke in the air is completely gone. Do not stand close to the  
unit. The sound produced by the device is loud because it is designed  
to awaken you in an emergency. Prolonged exposure to the horn at a  
close distance may be harmful to your hearing.

Figure 6: RECOMMENDED SMOKE ALARM LOCATION IN ROOMS  
WITH SLOPED, GABLED, OR PEAKED CEILINGS.  
The placement of the smoke alarm is critical if maximum speed of  
fire detection is desired. Thus, a logical location for a smoke alarm is  
the center of the ceiling. At this location, the device is closest to all  
areas of the room.  
INSTALLATION 9000 SERIES  
CAUTION: New Construction: DO NOT attach smoke alarm head  
until AFTER sanding, painting, and other dust creating situations are  
finished and cleaned up.  
WHERE SMOKE ALARMS SHOULD BE INSTALLED  
WIRING/GENERAL  
1. Use U.L. Listed cable with Class 1 insulation.  
2. Observe local code requirements. Use box connector to anchor  
cable to outlet box.  
IN MOBILE HOMES  
In mobile homes built after about 1978 that were designed and  
insulated to be energy-efficient, smoke alarms should be installed as  
described in the section above.  
3. Metal outlet boxes must be grounded to earth ground.  
4. NOTICE: Use only Duracell MN 1604 battery with the 9000  
Series smoke alarms. Available at many retail stores.  
CAUTION: Turn off electricity to prevent SHOCK and damage to  
smoke alarm. Be sure the power line to the unit is not controlled by  
any on/off switch, or other type of switch, other than a fuse or circuit  
breaker.  
IMPORTANT: Insure that all fluorescent lighting fixtures are properly  
grounded.  
NOTICE: Smoke alarm installation must conform to the electrical  
codes in your area and to Article 760 of the U.S. National Electrical  
Code. Wire installation should be performed only by a licensed  
electrician.  
In older mobile homes that have little or no insulation compared to  
today's standards, uninsulated metal outside walls and roofs can  
transfer heat and cold from outdoors, making the air right next to them  
hotter or colder than the rest of the inside air. These layers of hotter or  
colder air can prevent smoke from reaching a smoke alarm.  
Therefore, install smoke alarms in such units only on inside walls not  
more than 12 inches (30 cm) from the ceiling. If you are not sure  
about the insulation level in your mobile home, or if you notice that the  
walls or ceiling are unusually hot or cold, install the smoke alarm on an  
inside wall.  
Minimum protection requires one smoke alarm as close to the  
sleeping area as possible. For better protection, install one smoke  
alarm in each room, but first read the "Locations to Avoid."  
MOUNTING OUTLET BOX  
Use a 2" x 3" switch box or a 4" square or octagon junction box.  
Mount a box for each smoke alarm. If wall mounting is desired, be  
sure the box screws are oriented to upper right and lower left corners.  
Be sure to use supplied Mounting Plate.  
LOCATIONS TO AVOID  
Nuisance alarms are caused by placing smoke alarms where they  
will not operate properly. To avoid nuisance alarms, do not place  
smoke alarms:  
NOTE: For trouble areas where there can be a large volume of air  
blowing out through the electrical junction box. You must first insert  
the cardboard shield packaged with your smoke alarm to the backside  
of device before securing it to the mounting plate.  
In or near areas where combustion particles are normally  
present such as kitchens; in garages where there are particles of  
combustion in vehicle exhausts; near furnaces, hot water heaters, or  
gas space heaters. Install smoke alarms at least 20 feet (6 meters)  
away from kitchens and other areas where combustion particles are  
normally present.  
WIRING ONE SMOKE ALARM  
1. Run a minimum of 16 gauge, 2-conductor cable, plus ground  
(3 wires) to the junction box from a power supply. Smoke alarms shall  
be connected to their own dedicated circuit. Use ANSI/UL Listed  
Class 1 wire.  
In air streams passing by kitchens. Figure 7 shows how a  
smoke alarm can be exposed to combustion particles in normal air  
movement paths, and how to correct this situation.  
Figure 7  
NOTE: The wiring to be used shall be in accordance with the  
provisions of Article 300.3(b) of the National Electrical Code,  
NFPA 70, as well as Article 210.  
2. Make wire connections to the supplied plug-in connector as  
follows: black to black, white to white, and connect the ground  
wire to the metal outlet box.  
In damp or very humid areas, or next to bathrooms with showers.  
The moisture in humid air can enter the sensing chamber as water  
vapor, then cool and condense into droplets that cause a nuisance  
alarm. Install smoke alarms at least 10 feet (3 meters) away from  
bathrooms.  
In very cold or very hot environments, or in unheated buildings  
or outdoor rooms, where the temperature can go below or above the  
operating range of the smoke alarm. Temperature limits for proper  
operation are 40° to 100°F (4.4° to 37.8°C).  
In very dusty or dirty areas. Dust and dirt can build up on the  
smoke alarm's sensing chamber and can make it overly sensitive, or  
NOTE/RED-YELLOW WIRE: The red-yellow wire from the smoke  
alarm is for tandem connection only. DO NOT USE, AND DO NOT  
REMOVE INSULATION CAP UNLESS CONNECTING ANOTHER

9220F, TF, HF/9223F, TF, HF may be connected in tandem.  
All units connected in tandem MUST get their power from the same  
circuit, that is, all smoke alarms in tandem must be controlled by the  
same fuse or circuit breaker.  
c. To test smoke alarm for high sensitivity, turn test knob clockwise to  
TEST 2 position. Alarm should remain silent.  
d. Make sure to return test knob back to its normal position.  
e. If your smoke alarm sounds during this test it means the smoke  
alarm's sensitivity has become too high and may cause false  
alarms.  
After installation to verify proper working conditions all horns must  
sound in this system.  
NOTICE: If all interconnected alarms do not emit alarm signal during  
commissioning test, refer to “WIRING TWO OR MORE SMOKE  
ALARMS” section to insure alarm wiring is in accordance with tandem  
wiring diagam.  
CAUTION: Failure to observe any of the conditions set forth may  
cause system malfunction and damage to the smoke alarm.  
550-0093  
Page 9-5  
 
f. This could mean your smoke alarm is dirty and should be cleaned as  
described in the maintenance procedure below.  
IMPORTANT: IT IS RECOMMENDED TO CHANGE WASH AND  
RINSE WATER AFTER FIVE (5) SMOKE ALARMS. IF YOUR  
SMOKE ALARMS ARE EXTREMELY DIRTY, WATER SHOULD BE  
CHANGED MORE FREQUENTLY.  
NOTICE: SMOKE ALARMS ARE TO BE AIR DRIED ONLY. DO NOT  
PLACE ALARM IN OVEN, MICROWAVE OR USE A HOT AIR  
BLOWER TO ACCELERATE DRYING TIME. THIS COULD  
RESULT IN DAMAGE TO YOUR SMOKE ALARM.  
g. If the smoke alarm continues to alarm, for TEST 2 position following  
cleaning, return it to Gentex for service.  
h. To check for proper smoke entry into your smoke alarm's sensing  
chamber, Gentex recommends using the Home Safeguard Smoke  
Spray or CHEKKIT® SMOKE Detector Tester from SDI.  
i. This test should be performed once a year and should be sprayed  
from a distance no closer than 12 inches from the smoke alarm.  
In the event you experience difficulty in the cleaning of your smoke  
alarm or if you have any questions, please contact Gentex Corporation  
or your local Gentex distributor.  
MAINTENANCE  
After your smoke alarm has been in operation for a period of time or  
if it was installed prior to the completion of all building construction, your  
device may have become more sensitive due to dirt build-up in the  
smoke alarm's optic sensing chamber which could cause nuisance  
alarms or could cause activation from small amounts of smoke build-up.  
If this should occur, following this simple washing procedure will  
restore your smoke alarm back to its original condition.  
For further information, regarding frequency of cleaning and testing,  
refer to NFPA 72, NFPA, Batterymarch Park, Quincy, MA 02269.  
NOTICE: Failure to follow full cleaning instructions could result in  
damage to this smoke alarm. DO NOT remove all smoke alarms at  
the same time for cleaning.  
If the smoke alarm does not work properly, do not try  
and fix it yourself. This will void your warranty. See "To Return a  
Smoke Alarm" for instructions to return smoke alarms that do not  
operate properly. DO NOT TRY TO FIX IT YOURSELF.  
IMPORTANT: Gentex recommends smoke alarms be tested a  
minimum of once a week.  
WARNING! Never use an open flame of any kind to test your smoke  
alarm. You may ignite and damage the smoke alarm as well as your  
home. The test feature of your smoke alarm accurately simulates  
smoke conditions and tests the smoke alarm's functions as required by  
ANSI/UL 217.  
1. Turn off electrical power to the smoke alarm.  
2. Rotate the smoke alarm counter-clockwise to remove it from its  
mounting plate.  
3. Unplug the connector from the back of the smoke alarm. Do not  
remove the wire connection; leave the connector for your  
replacement smoke alarm or jumper plug. Remove the battery.  
4. Select three (3) standard size wash buckets and fill them each with  
one gallon of normal tap water (distilled or de-ionized treated water  
is recommended as a final rinse if water is extremely hard in  
your area).  
WARNING! Do not cover, tape, or otherwise block the openings of  
your smoke alarm. These openings are designed to allow air to pass  
through your smoke alarm, thus sampling the air around the smoke  
alarm.  
WARNING! Smoke alarms are not to be used with detector guards  
unless the combination has been evaluated and found suitable  
for that purpose.  
FAILURE TO REGULARLY CLEAN THIS SMOKE ALARM WILL  
RESULT IN FALSE ALARMS. A BUILD UP OF DUST CREATES AN  
OBSCURATION THAT SIMULATES SMOKE. THIS MEANS THE  
UNIT WILL GO INTO ALARM WITHOUT A FIRE CONDITION.  
5. Add 1/8 cup of Ivory dishwashing liquid to the first bucket of water  
and allow it to mix thoroughly, then place one dirty smoke alarm into  
the soap water mixture until it becomes completely covered or  
submerged. NOTE: If the smoke alarms are exceptionally dirty, you  
may wish to first wipe off any excess dirt before washing unit so as  
not to dirty the wash water too quickly.  
DO NOT open smoke alarm for cleaning. IF SMOKE ALARM IS  
OPENED DURING CLEANING, PRODUCT WARRANTY BECOMES  
VOID.  
TO RETURN A SMOKE ALARM  
Should you experience problems with your smoke alarm, proceed

6. Allow smoke alarm to soak for approximately 10 minutes (longer  
if extremely dirty). Then agitate for 5 or 10 seconds to flush out any  
remaining dirt left inside smoke alarm's housing.  
7. Remove smoke alarm from wash water and transfer directly to one of  
the first rinse buckets containing clear water. Again, allow smoke  
alarm to become completely submerged, agitate once more for 5 or  
10 seconds to remove soap residue.  
8. Finally, transfer smoke alarm to your second and final rinse bucket,  
repeating method found in Step 7, then remove smoke alarm to a  
clean dry area for a period of 48 hours to allow it to thoroughly dry.
