Wireless Smoke Alarm User’s Guide  
Wireless Smoke Alarm with SMART HUSH® Control to temporarily silence  
nuisance alarms and battery backup.  
Thank you for purchasing a Kidde Wireless AC Powered Smoke Alarm, part of  
the Kidde Wireless System. It is an important part of your familys home safety  
plan. You can trust this product to provide the highest level of quality and per-  
formance. We know you expect nothing less when the lives of your family are at  
stake. This alarm, in combination with other Kidde Wireless products, provides  
you with an interconnected alarm system without having the inconvenience or  
extensive labor of rewiring your home. An interconnected alarm system provides  
an earlier warning to smoke or fire by linking alarms so that when one unit  
sounds, it will trigger all other units to sound, thereby giving a family more time  
to escape. Kidde estimates that nearly 100 million U.S. homes either do not  
have interconnected smoke alarms, or have limited coverage. For homes that do  
have interconnected systems, this battery powered alarm can provide additional  
fire protection in other areas of the home.  
For your convenience, write down the following information. If you call  
our Consumer Hotline, these are the first questions you will be asked.

WARNING! Ionization sensing alarms may detect invisible fire parti-  
cles (associated with fast flaming fires) sooner than photoelectric  
alarms. Photoelectric sensing alarms may detect visible fire particles  
(associated with slow smoldering fires) sooner than ionization  
alarms. Home fires develop in different ways and are often unpre-  
dictable. For maximum protection, Kidde recommends that both  
Ionization and Photoelectric alarms be installed.

1. RECOMMENDED LOCATIONS FOR ALARMS  
• Locate the first alarm in the immediate area of the bedrooms. 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 to monitor any stairway as they act as chimneys for  
smoke and heat.  
• Locate at least one alarm on every floor.  
• Locate an alarm in every bedroom.  
• Locate an alarm in every room where electrical appliances operate (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. Kidde recommends installing a Wireless Smoke Sounder in all  
rooms where older adults, individuals with partial hearing loss, and children  
sleep.  
• Smoke, heat, and combustion products rise to the ceiling and spread hori-  
zontally. Mounting the smoke alarm in the center of the ceiling places it clos-  
est to all points in the room. Ceiling mounting is preferred in ordinary resi-  
dential construction.  
• For mobile home installation, select locations carefully to avoid thermal barri-  
ers that may form at the ceiling. For more details, see MOBILE HOME INSTAL-  
LATION below.  
• When mounting an alarm on the ceiling, locate it at a minimum of 4” (10  
cm) from the sidewall (see Figure 1).  
• 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 (see Figure 1).  
• 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). NFPA 72 states: “Smoke  
alarms in rooms with ceiling slopes greater than 1 foot in 8 feet (.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” (see Figure 3).

MOBILE HOME INSTALLATION  
Modern mobile homes have been designed and built to be energy efficient.  
Install smoke alarms as recommended above, refer to RECOMMENDED LOCA-  
TIONS and Figure 1. In older mobile homes that are not well insulated com-  
pared 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 that 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 at a minimum of 4” (10 cm) and 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 and ceiling are either  
hot or cold, install the alarm on an inside wall. For minimum protection, install  
at least one alarm close to the bedrooms. For additional protection, see SINGLE  
FLOOR PLAN in Figure 2.  
WARNING: TEST YOUR SMOKE ALARM OPERATION AFTER R.V. OR  
MOBILE HOME VEHICLE HAS BEEN IN STORAGE, BEFORE EACH TRIP  
AND AT LEAST ONCE A WEEK DURING USE.  
2. LOCATIONS TO AVOID  
• In the garage. Products of combustion are present when you start your auto-  
mobile.  
• Less than 4” (10cm) from the peak of an “A” frame type ceiling.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
• 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 alarm or a failure to alarm.  
• In very humid areas. Moisture or steam can cause nuisance alarms.  
• In insect-infested areas.  
• Smoke alarms should not be installed within 3 ft (.9m) of the following: the  
door to a kitchen, the door to a bathroom containing a tub or shower,  
forced air supply ducts used for heating or cooling, ceiling paddle or whole  
house ventilating fans, or other high air flow areas.  
• Kitchens. Normal cooking may cause nuisance alarms. If a kitchen alarm is  
desired, it should have an alarm silence feature or be a photoelectric type.  
• Near fluorescent lights, amateur radios, electrical equipment or other devices  
known to transmit in the RF band. Electronic “noise” may cause nuisance  
alarms.  
• Near large metal surfaces and bundles of wire.  
• Smoke alarms are not to be used with detector guards unless the combination  
(alarm and guard) have been evaluated and found suitable for that purpose.  
3. INSTALLATION INSTRUCTIONS  
WIRELESS INTERCONNECT SETUP  
1. Remove your new Kidde Wireless Interconnect devices from their respective  
packages and place them in front of you.  
DO NOT PLUG THEM IN OR INSTALL THE BATTERIES.  
2. Find the 8-position dipswitch located on  
the back of each device. For this model,  
the dipswitch is located under the battery  
door (see Figure 4).  
3. Select one of the units. You will define the  
ID of your system by positioning the  
switches of the dipswitch in a random pat-  
tern. The ID will need to be the same for  
FIGURE 4  
each alarm or accessory. This ID will differentiate your alarm system from  
similar systems nearby. DO NOT USE THE DEFAULT ID YOUR UNITS ARE  
SHIPPED WITH!  
Download from Www.Somanuals.com. All Manuals Search And Download.  
4. Using a pen or pencil, change the switches in each of the Kidde Wireless  
devices to match the pattern you selected in step 3. Ensure that the  
sequence is not reversed.  
5. Power each unit after setting the ID by installing the batteries. The alarms  
only read the ID that has been set when they are first supplied power. Any  
changes to the switch after the unit is powered will not be recognized, and  
will require the power to be removed for a minimum of 30 seconds before  
powering again.  
6. Push and hold the test button on each unit for at least 5 seconds, or until  
all the devices produce an alarm. If all the units do not produce an alarm,  
refer to the trouble-shooting section at the end of the users guide.  
CAUTION: Due to the loudness of the alarm, always stand an arm’s  
length away from the unit when testing.  
7. Install the alarms in accordance with the users guide as described in section  
1, and repeat step 6. Since wireless communication can be interrupted by  
a number of factors, you must test your alarms weekly to ensure proper  
communication between alarms.  
8. Read the users guide and keep it in a safe place for future reference.  
If your Wireless smoke alarms enter alarm mode, first check to see if  
there is a fire. If a fire does not exist, and the test buttons have not  
been activated on any of the units, it is likely that you are receiving  
interference from a similar system nearby. In this case, repeat the above  
steps and select a different dipswitch pattern, making sure to disconnect  
power and remove the batteries before changing the switch positions.  
WIRING REQUIREMENTS  
• This smoke alarm should be installed on a U.L. listed or recognized junction  
box. All connections should be made by a qualified electrician and all wiring  
used shall be in accordance with articles 210 and 300.3(B) of the U.S. National  
Electrical Code ANSI/NFPA 70, NFPA 72 and/or any other codes having jurisdic-  
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 addition, the  
resistance of the interconnect wiring shall be a maximum of 10 ohms.  
• The appropriate power source is 120 Volt AC Single Phase supplied from a  
non-switchable circuit that is not protected by a ground fault interrupter.  
WARNING: This alarm cannot be operated on power derived from a square  
wave, modified square wave or modified sine wave inverter. These types of  
inverters are sometimes used to supply power to the structure in off grid instal-

lations, such as solar or wind derived power sources. These power sources pro-  
duce high peak voltages that will damage the alarm.  
WIRING INSTRUCTIONS FOR AC QUICK CONNECTOR  
CAUTION! TURN OFF THE MAIN POWER TO THE CIRCUIT BEFORE  
WIRING THE ALARM.  
• If you are using the Kidde Wireless AC Powered alarms to replace Hardwired  
alarms that are not interconnected (see definitions on Quick Setup Guide),  
DO NOT CONNECT THE RED WIRE TO ANYTHING. Leave the red wire-insulat-  
ing cap in place to make certain that the red wire cannot contact any metal  
parts or the electrical box.  
• When alarms are interconnected, all interconnected units must be powered  
from a single circuit.  
• Only one Wireless AC Powered alarm may be used when all existing alarms  
are Hardwired with Interconnect (see definitions on Quick Setup Guide).  
• A maximum of 24 devices may be hardwire interconnected in a multiple sta-  
tion arrangement. The interconnect system should not exceed the NFPA inter-  
connect limit of 12 smoke alarms and/or 18 alarms total (smoke, heat, carbon  
monoxide, etc.). With 18 alarms interconnected, it is still possible to intercon-  
nect up to a total of 6 remote signaling devices and/or relay modules.  
Kidde alarms and accessories CAN ONLY BE interconnected with other  
Kidde alarms and accessories as well as specified brands and models of  
interconnect compatible alarms. Connection of Kidde products to a non-  
specified manufacturer’s interconnect system, or connection with non-  
specified equipment from another manufacturer into an existing Kidde  
system could result in nuisance alarming, failure to alarm, or damage to  
one or all of the devices in the interconnect system. Refer to User’s  
Guide supplied with each Kidde product for lists of interconnect compat-  
ible models, brands, and devices.  
• When mixing models that have battery backup (1275, 1276, 1285, 1296,  
i12040, i12060, i12080, PE120, PI2000, KN-COSM-IB, HD135F, KN-COB-IC,  
KN-COP-IC) with models without battery backup ((1235, i12020, KN-COSM-  
I, 120X, SM120X, CO120X, SL177i), be advised that the models without bat-  
tery backup will not respond during an AC power failure.  
• For more information about compatible interconnect units and their func-  
• The maximum wire run distance between the first and last unit in an inter-  
connected system is 1000 feet.

IN THE BATTERY COMPARTMENT BY THE BATTERY, THE BATTERY  
DOOR WILL NOT CLOSE, THE AC QUICK CONNECTOR WILL NOT  
ATTACH TO THE ALARM, AND THE ALARM WILL NOT ATTACH TO  
THE MOUNTING BRACKET.  
After installing the battery, connect your alarm to the AC Quick Connector and  
mount the unit. Test your alarm by using the test/reset button and check that  
the green LED is on.  
A missing or improperly installed battery will prevent the battery door from clos-  
ing and result in improper alarm operation. This smoke alarm uses a 9V alkaline  
battery (lithium batteries may also be used). A fresh battery should last for one  
year under normal operating conditions. This alarm has a low/missing battery  
monitor circuit that will cause the alarm to “chirp” approximately every 60 sec-  
onds for a minimum of seven (7) days when the battery gets low. Replace the  
battery when this condition occurs.

Tamper Resist Features  
Locations of Posts  
FIGURE 9A  
FIGURE 9B  
This alarm has a tamper resist feature, which helps prevent someone from  
removing the unit from the mounting bracket. Activate the smoke alarm tamper  
resist feature by breaking off the four posts in the square holes in the mounting  
bracket (see Figure 9A). 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 bracket. NOTE: To  
remove the alarm when the tamper resist tab is engaged, press down on the  
the tamper resist tab, and rotate the alarm off the bracket (see Figure 9B).  
4. OPERATION AND TESTING  
OPERATION  
The smoke alarm is operating once AC power is supplied, a fresh battery is  
installed and testing is complete. When the smoke alarm ionization chamber  
senses products of combustion, the horn will sound a loud (85db) temporal  
alarm until the sensing chamber is cleared of smoke particles.  
Smart HUSH® CONTROL: The Smart HUSH® feature has the capability of tem-  
porarily desensitizing the smoke sensing circuitry in order to quiet your alarm  
while you take care of a non-emergency event. This feature is to be used only  
when a known alarm condition, such as smoke from cooking, activates the  
alarm. Activate Smart HUSH® control by pushing the button on the smoke alarm  
cover. If the smoke is not too dense, the alarm will silence immediately. The  
green LED will blink every 2 seconds for approximately 7 minutes to indicate  
that the alarm is in a temporarily desensitized condition. The smoke alarm will  
automatically reset after approximately 7 minutes, and will sound again if parti-  
cles of combustion are still present. The Smart HUSH® feature can be used  
repeatedly until the air has been cleared of the condition causing the alarm.  
Pushing the test button on the alarm will end the HUSH® period.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Remote HUSH® CONTROL: Press the button on any Kidde Wireless device to acti-  
vate the Smart HUSH® feature on the Wireless smoke alarm that is initiating an  
alarm. This allows you to enable the Smart HUSH® feature on an alarm that may  
be installed in an area that is difficult to reach. This feature should only be used  
when a known alarm condition, such as smoke from cooking, activates the alarm.  
NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH® CONTROL FEATURE  
AND SOUND A CONTINUOUS ALARM.  
CAUTION: BEFORE USING THE ALARM HUSH® FEATURE, IDENTIFY  
THE SOURCE OF THE SMOKE AND BE CERTAIN A SAFE CONDITION  
EXISTS.  
Low Battery HUSH® CONTROL: When the battery needs to be replaced, the unit  
will produce a low battery “chirp” once per minute. The Low Battery HUSH®  
feature allows you to press the button on the alarm producing the warning and  
disable the “chirp” for a random period of up to 12 hours. This gives you a  
chance to replace the battery at a more convenient time without sacrificing your  
safety by disconnecting the alarm from power. During this Low Battery HUSH®  
period, your alarm is performing normally and is not desensitized.  
LED Indicator Operation  
Red LED:  
The red LED will flash in conjunction with the alarm beep. Therefore, the red  
LED will flash during a smoke alarm, a low battery mode chirp and a unit error  
mode chirp.  
Green LED:  
The green LED will illuminate as described below:  
STANDBY CONDITION (powered by AC and battery backup) - The LED will  
be constantly on.  
STANDBY CONDITION (powered by only battery backup) - The LED will  
flash approximately every 10 seconds.  
INITIATING ALARM INDICATOR - The LED will flash every second while  
sounding an alarm to signify that the alarm sensed a smoke hazard. This  
will only be displayed on the alarms that sensed smoke. The remaining  
interconnected alarm will sound but will not display the initiating indicator.  
The initiating indicator varies from model to model. See the users guide  
for each specific model of interconnected alarm for a description of the  
initiating alarm indicator.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
ALARM MEMORY CONDITION - The LED will flash every second signifying  
that the alarm sensed a smoke hazard. It will continue to flash every sec-  
ond until the test/reset button is pressed, thus resetting the alarm.  
HUSH® MODE CONDITION - The LED will flash every 2 seconds while the  
alarm is in HUSH® mode.  
TESTING  
TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION.  
When testing, ensure that all units activate in response to a push to test from  
another unit. This will verify that changes in your environment (i.e. moved furni-  
ture, addition of electronic appliances) have not adversely effected the operation  
of your Wireless system.  
Remote Push To Test: Test your Kidde Wireless alarm system by activating the test  
button on any Kidde Wireless alarm for a minimum of 5 seconds, or until all of  
the interconnected alarms sound. When the other alarms respond, this verifies  
that both the alarms and the interconnect system are functioning properly.  
It may take up to 12 seconds for your Wireless interconnected alarms to  
enter alarm mode in response to a remote push to test.  
If the alarm does not sound, check the fuse or circuit breaker supplying power  
to the alarm circuit. If the alarm still does not sound, the unit may have defec-  
tive batteries or other failure and you should call Kidde customer service at 1-  
800-880-6788. If other interconnected alarms do not produce an alarm signal,  
see the trouble-shooting guide in section 12.  
DO NOT use an open flame to test your alarm; you could damage the alarm or  
ignite combustible materials and start a structure fire.  
Erratic or low sound coming from your alarm may indicate a defective alarm,  
and it should be returned for service (see Section 13).  
5. NUISANCE ALARMS  
Smoke alarms are designed to minimize nuisance alarms. Cigarette smoke will  
not normally set off the alarm, unless the smoke is blown directly into the  
alarm. Combustion particles from cooking may set off the alarm if the alarm is  
located close to the cooking area. 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 remove these com-  
bustible products from the kitchen.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Model RF-SM-ACDC has a HUSH® button 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 does sound, check for fires  
first. If a fire is discovered, get out and call the fire department. If no fire is pres-  
ent, check to see if one of the reasons listed in Section 2 may have caused the  
alarm.  
In rare occasions, interference from other electronic devices may cause nuisance  
alarms. If you do get nuisance alarms, please refer to the trouble-shooting guide  
at the end of this and each of your Kidde Wireless products’ users guides.  
6. MAINTENANCE  
ALARM REMOVAL  
IF THE SMOKE ALARM’S TAMPER RESIST FEATURE HAS BEEN ACTIVATED,  
REFER TO THE PARAGRAPH ON SMOKE ALARM TAMPER RESIST FEATURE  
IN SECTION 3 FOR REMOVAL INSTRUCTIONS.  
To remove the alarm from the trim ring, rotate the alarm counter clockwise in  
the direction of the "OFF" arrow on the cover. To disconnect the AC power,  
squeeze the locking arms on the sides of the AC Quick Connector while pulling  
the connector away from the bottom of the alarm (see Section 3, Figure 3).  
ALARM REPLACEMENT  
Ten years after initial power-up, this unit will “chirp” every 30 seconds to indi-  
cate that it is time to replace the alarm. A label has been provided on the side  
of the alarm that has “Replace by” printed on it. Write the replace by date on  
the label. The date written on the label should be after ten (10) years of cumu-  
lative power. NOTE: Chirping once a minute is an indication of a low battery  
where as the indication for replacement is once every 30 seconds.  
BATTERY INSTALLATION AND REMOVAL  
Battery Replacement  
If any form of battery failure is detected, the red LED light will flash and the unit  
will “chirp” once every minute.  
Refer to Section 3, BATTERY INSTALLATION and the inside of the battery  
door.

Alkaline type: ENERGIZER 522; DURACELL MN1604 OR MX1604; GOLD PEAK  
1604A; PANASONIC 6AM6, 6AM-6, 6AM-6PI, 6AM6X, and 6LR61(GA).  
Lithium type: ULTRALIFE U9VL-J  
NOTE: WEEKLY TESTING IS REQUIRED!  
WARNING! BE SURE TO FOLLOW BATTERY INSTALLATION INSTRUC-  
TIONS PRINTED ON THE INSIDE OF THE BATTERY DOOR OF THE  
ALARM AND USE ONLY THE BATTERIES SPECIFIED. USE OF DIFFER-  
ENT BATTERIES MAY HAVE A DETRIMENTAL EFFECT ON THE SMOKE  
ALARM AND MAY CAUSE IT NOT TO FUNCTION AS INTENDED.  
CONSTANT EXPOSURES TO HIGH OR LOW TEMPERATURES OR HIGH  
HUMIDITY MAY REDUCE BATTERY LIFE.  
CLEANING YOUR ALARM  
YOUR ALARM SHOULD BE CLEANED AT LEAST ONCE A YEAR  
To clean your alarm, remove it from the mounting bracket as outlined in the  
beginning of this section. You can clean the interior of your alarm (sensing  
chamber) by using compressed air or a vacuum cleaner hose around the perime-  
ter of the alarm. The outside of the alarm can be wiped with a damp cloth.  
After cleaning, reinstall your alarm, verify the green LED is on and test your  
alarm by using the test button. If cleaning does not restore the alarm to normal  
operation the alarm should be replaced.  
7. LIMITATIONS OF SMOKE ALARMS  
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY  
• NFPA 72 states: Life safety from fire in residential occupancies is based prima-  
rily on early notification to occupants of the need to escape, followed by the  
appropriate egress actions by those occupants. Fire warning systems for  
dwelling units are capable of protecting about half of the occupants in  
potentially fatal fires. Victims are often intimate with the fire, too old or  
young, or physically or mentally impaired such that they cannot escape even  
when warned early enough so that escape should be possible. For these peo-  
ple, other strategies such as protection-in-place or assisted escape or rescue  
are necessary.  
Smoke alarms are devices that can provide early warning of possible  
fires at a reasonable cost; however, alarms have sensing limitations.

Photoelectric sensing alarms may detect visible fire particles (associat-  
ed with slow smoldering fires) sooner than ionization alarms. Home  
fires develop in different ways and are often unpredictable. For maxi-  
mum protection, Kidde recommends that both Ionization and  
Photoelectric alarms be installed.  
• A battery-powered alarm must have a battery of the specified type, in good  
condition and installed properly.  
• AC powered 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 tested regularly to make sure the batteries 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, walls, on  
roofs, on the other side of a closed door or on a different floor.  
• 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 ones 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.  
• Although smoke alarms can help save lives by providing an early warning of  
a fire, they are not a substitute for an insurance policy. Homeowners and  
renters should have adequate insurance to protect their lives and property.  
8. GOOD SAFETY HABITS  
DEVELOP AND PRACTICE A PLAN OF ESCAPE  
• 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.  
• Make a floor plan indicating all doors and windows and at least two (2)  
escape routes from each room. Second story windows 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.  
• Determine a place outside your home where you all can meet if a fire occurs.  
• Familiarize everyone with the sound of the smoke alarm and train them to  
leave your home when they hear it.

• Practice a fire drill at least every six months, including fire drills at night when  
family members are asleep to see who responds. If someone doesn’t wake  
up, assign an adult to wake and assist that individual in the event of a fire.  
Kidde recommends that parents plan on alerting and assisting children.  
Practice allows all occupants to test your plan before an emergency. It is  
important they know what to do.  
• Current studies have shown smoke alarms may not awaken all sleeping indi-  
viduals, 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  
evacuating the area unassisted.  
WHAT TO DO WHEN THE ALARM SOUNDS  
• Leave immediately by your escape plan. Families have on average less than  
three minutes to escape a fire so don’t waste time getting dressed or picking  
up valuables.  
• In 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.  
• Stay close to the floor if the air is smoky. 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 from your neighbors home - not from yours!  
• Don’t return to your home until the fire officials say that it is all right to do so.  
• 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  
9. NRC INFORMATION  
Ionization type smoke alarms use a very small amount of a radioactive element  
in the sensing chamber to enable detection of visible and invisible combustion  
products. The radioactive element is safely contained in the chamber and  
requires no adjustments or maintenance. This smoke alarm meets or exceeds all

government standards. It is manufactured and distributed under license from  
the U.S. Nuclear Regulatory Commission.  
10. NFPA REQUIRED PROTECTION  
The National Fire Protection Associations Standard 72 provides the following  
information:  
Smoke Detection - Where required by applicable laws, codes, or standards for  
the specified occupancy, approved single- and multiple-station smoke alarms  
shall be installed as follows: (1) In all sleeping rooms Exception: Smoke alarms  
shall not be required in sleeping rooms in existing one- and two-family dwelling  
units. (2) Outside of each separate sleeping area, in immediate vicinity of the  
sleeping rooms. (3) On each level of the dwelling unit, including basements  
Exception: In existing one- and two-family dwelling units, approved smoke  
alarms powered by batteries are permitted.  
Smoke Detection - 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, it is recommended that the householder consider the  
use of additional smoke alarms for those areas for increased protection. The  
additional areas include the basement, bedrooms, dining room, furnace room,  
utility room, and hallways not protected by the required smoke alarms. The  
installation of the smoke alarms in the kitchen, attic (finished or unfinished), or  
garage is normally not recommended, as these locations occasionally experience  
conditions that can result in improper operation. This equipment should be  
installed in accordance with the National Fire Protection Associations Standard  
72 (NFPA, Batterymarch Park, Quincy, MA 02269).  
NOTIFY YOUR LOCAL FIRE DEPARTMENT AND INSURANCE COMPANY OF YOUR  
SMOKE ALARM INSTALLATION.  
11. CAUTION (AS REQUIRED BY THE CALIFORNIA STATE FIRE  
MARSHAL)  
“Early warning fire detection is best achieved by the installation of fire detection  
equipment in all rooms and areas of the household as follows. A smoke alarm  
installed in each separate sleeping area (in the vicinity of, but outside of the  
bedrooms), and heat or smoke detectors in the living rooms, dining rooms, bed-  
rooms, kitchens, hallways, attics, furnace rooms, closets, utility and storage  
rooms, basements and attached garages.”
