Ionization Smoke Alarm
These are the least expensive, costing between $5 and $10 each, and they are more responsive to the physical flaming stage of a fire.
Photoelectric Smoke Alarms
These cost between $10 and $15 each, and they are generally more responsive to fires that begin with a long period of smoldering.
This type of smoke alarm combines both the ionization smoke detector and the photoelectric smoke detector. These alarms usually cost between $18 and $30 each.
While ionization smoke alarms are by far the most popular and are currently found in an estimated 93 percent of U.S. homes, they aren’t the most reliable. Indiana’s new smoke alarm policy advocates that all Indiana homes be equipped with photoelectric or dual-sensor smoke alarms for better overall protection. To see what kind of smoke alarm you currently have in your home, look at the detector itself.
Photoelectric smoke detectors usually have the word “PHOTOELECTRIC” right on them. They might also have a large “P” or a blue symbol. If you see the words “dual sensor,” this means that your smoke detector is both an ionization alarm and a photoelectric alarm.
If, after looking at your alarm, you don’t see any words or symbols, chances are it’s probably an ionization smoke alarm. Consider updating all the smoke alarms in your house to dual-sensor alarms for the best protection, and remember to always check your smoke alarms’ batteries.
