HOW MANY DO I NEED AND WHAT KIND SHOULD I GET?????
There are two types of smoke detectors.
One type is called an ionization smoke detector because it monitors "ions", electrically charged particles. Smoke particles entering the sensing chamber change the electrical balance of the air. The alarm sounds when the change in electrical balance reaches a pre-set level.
The other type is called a photoelectric smoke detector because its sensing chamber uses a beam of light and a light sensor. Smoke particles entering the chamber change the amount of light that reaches the light sensor. The alarm sounds when the smoke density reaches a pre-set level.
Both types of smoke detectors are acceptable and perform effectively, provided they are installed and maintained correctly.
It is required that every home have at least one smoke detector in each bedroom, outside each sleeping area, and on every level of the home, including the basement.
Ensure everyone sleeping in your home can hear the sound of the smoke detector when it alarms and the bedroom doors are closed. If anyone is hearing impaired, install special smoke detectors that will alert him or her.
HOW OFTEN SHOULD I TEST MY DETECTOR, AND WHEN SHOULD I BUY A NEW ONE???
It is very important to test and clean all smoke detectors regularly.
Test your smoke detectors by pressing the test button once a month.
Vacuum your smoke detectors twice a year to remove any dirt or dust from the sensing chamber.
For battery operated smoke detectors, change the battery at least once a year. Remember, never "borrow" the smoke detector's battery for another use.
Smoke detectors do not last forever. Smoke detectors that are older than 10 years are near the end of their service life and should be replaced.
