Where Should Smoke Detectors be Located?

Every home should have smoke detectors and they should be placed on every level of the home including the basement. The detectors should be placed outside every sleeping area and the bed should be no more than twenty feet from the alarm. If there is people in the home that sleep with the door closed, then a smoke alarm should be installed both inside and outside of that room.

Two Different Kinds of Smoke Detectors

Most people don’t know that there are different kinds of smoke detectors and that each one serves a different purpose. Knowing the difference will have a better chance at saving a persons life.

A photoelectric smoke detector uses ultraviolet light, a photoelectric receiver, and a lens. All of the components are arranged inside a vented chamber so that air can flow. If there is smoke, it will move through this chamber. There is also an LED light that sends a beam of light across the chamber. There is a separate compartment inside where there is a photosensor that detects the light. As the smoke enters this area, the smoke interrupts the light, which causes the light to scatter toward the light sensor. This makes the alarm sound. Photoelectric smoke alarms are very responsive to fires.

According to the National Fire Protection Association, photoelectric smoke alarms are outstanding at providing proper warning for the different types of fires. They give homeowners more time to get out of the house when a fire begins.

An ionization smoke detector contains americium-241 in a very small amount. It is housed in an ionization chamber. This produces an electric current between a pair of metal plates, which is what sounds the alarm. This happens because these metal electrodes are connected to the battery. When in contact with americium-241, air molecules are converted into positive and negative ions. When smoke enters the alarm, these ions bond with the smoke, causing the alarm to sound.

Ionization smoke alarms are typically more responsive to an active fire. This type of alarm can detect a small amount of smoke. If food on the stove starts to catch fire, the alarm is going to detect it. That is why this type of fire alarm is currently found in kitchens. However, this type of alarm may not sound in enough time to allow a homeowner to get out fast.
