After cleaning, reinstall your alarm and test your alarm by using the test button. Check that the green LED is on. 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 primarily 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 men- tally impaired such that they cannot escape even when warned early enough that escape should be possible. For these people, other strategies such as protection-in-place or assisted escape or res- cue are necessary.

Smoke alarms are devices that can provide early warning of possible fires at a reasonable cost; however, alarms have sensing limitations. Ionization type alarms offer a broad range of fire sensing capabilities but are better at detecting fast flaming fires than slow smoldering fires. Photoelectric alarms sense smoldering fires better than flaming fires. Home fires develop in different ways and are often unpredictable. Neither type of alarm (photoelectric or ionization) is always best, and a given alarm may not always provide warning of a fire.

A battery powered alarm must have a battery of the specified type, in good condition and installed properly.

A.C. powered alarms will not operate if the A.C. 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, wall, 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 sleep- er.

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.

Although smoke alarms can help save lives by providing an early warning of a fire, they are not a substitute for an insurance policy. Home owners and renters should have adequate insurance to protect their lives and property.

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.

8. GOOD SAFETY HABITS

DEVELOP AND PRACTICE A PLAN OF ESCAPE

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. Practice allows you to test your plan before an emer- gency. You may not be able to reach your children. It is important they know what to do.

WHAT TO DO WHEN THE ALARM SOUNDS

Leave immediately by your escape plan. Every second counts, 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 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.

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 con- tained 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.
