Smoke Alarm Types Detectors come in two common types - the ionization and the photoelectric variety. Ionization smoke detectors feature a harmless radioactive source within a dual detection chamber. Ionization detectors respond to invisible by-products of combustion. They operate by sensing for a change in the electrical conductivity across the detection chamber. Photoelectric smoke detectors work on an entirely different principle. Photoelectric detectors look for the presence of visible by-products of combustion in the detection chamber. When a sufficient density of visible combustibles fill the detection chamber, the detector sounds an alarm condition.

Things to Look for in HOME Smoke Detectors. Any smoke detector you install should have a test button. As a test, when the button is depressed, the audible alarm sounds the warning signal. Batteries should be included and are to last more than one year. It should conform to high quality standards set forth by major agencies and organizations.

How Good Are HOME Smoke Detectors? They are very good indeed. The common home smoke detector cost around PhP 1,000.00 and will detect smoke in very small concentrations in the home. Smoke emission occurs during the early stages of a fire, so smoke detectors in the ceilings of the home will provide plenty of early warning in the event of a fire.
