6m from the sources of combustion particles(stove,furnace,water heater,space heater)if
possible.Ventilate these areas as much as possible.
In air streams near kitchens.Air currents can draw cooking smoke into the sensing chamber of a smoke
alarm near the kitchen.
In very damp,humid or steamy areas,or directly near bathrooms whith showers.Keep units at least 3m
away from showers saunas,dishwhashers,etc.

buildings,outdoor rooms,porches,or unfinished attics or basements.
In very dusty,dirty,or greasy areas.Don't install a smoke alarm directly over the stove or range.Clean a
laundry room unit frequently to keep it free of dust or lint.
Near fresh air vents,ceiling fans,or in very drafty areas.Drafts can blow smoke away from the
unit,preventing it from reaching the sensing chamber.

TEST
It is important to test this unit weekly to make sure it is working properly. Don't open the alarms
by yourself, return them to the seller if improperly, and don't use fire to test your alarms.
Press and hold the test button on the cover of the unit until the alarm sounds. If it does not alarm, make
sure that the unit is receiving power and test it again. If it still does not alarm, replace it immediately or
check your battery.
The signal flashes once 30 seconds and while it alarms the signal will flash once 0.5 second.
If the alarm makes low "chirp" sounds every about 30seconds,it tells you to exchange your battery.
Little smoke will not cause alarms, so misinformation occurs only when you blow smoke to the alarms
directly or you forget to turn on your ventilated facility while your cooking.
Sometimes when you smoke the unit will alarm, so you can just blow air to it to stop alarming.

REGULAR MAINTENANCE
Never use water, cleaners or solvents to clean your smoke alarm since they may damage the unit.
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. Open the cover and disconnect the battery, gently vacuum the inside of
the cover and the sensor chamber, reconnect the battery.close the smoke alarm and vacuum the outside
of the cover, test the smoke alarm.
Use these batteries to replace the old one.
Carbon zinc:EVEREADY 216 OR 2122;GOLDPEAK 1604P OR 1604S
Alkaline:EVEREADY 522 DURACELL MN1604 MS1604;GOLDPEAK 1604A
Lithium: ULTRALIFE U9VL
You'd better use good battery to make the alarm work long, some batteries can use more than 1 year.

LIMITATIONS OF SMOKE ALARMS
United States NFPA72 tells that the safety of life is to be noticed by alarms before fire, to confirm the
correct escape way. The fire systems help half of residents escape and we should help the old people,
women and children more because they are always the victims.
Smoke alarms are not foolproof, they can't prevent or extinguish fires,they are not a substitute for
property or life insurance.You need buy some fire fighting facilities.
Sometimes the smoke is blocked by objects and can't reach the detector, and if the wind blows the
smoke away from the detector, the unit won't work either.

HOW TO DO IN CASE OF FIRE
Call the Fire Department immediately after confirming the fire.
Don't panic,stay calmly and follow your family escape plan.Get out of the house as quickly as
possible,don't' stop to get dressed or collect anything.
Feel doors before opening them to see if they are hot.If a door is cool,open it slowly.Don't open a hot
door-use an alternate escape route
Cover your nose and mouth with a cloth (preferably wet). Take short, shallow breath.
Meet at your planned place outside your home, and do a head count to ensure everybody go out safely.
