Photoelectric smoke detectors usually have the word PHOTOELECTRIC right on them. You might see a big "P" or a "blue symbol". And if you see the words "dual sensor," that means the smoke detector has both photoelectric and ionization built in.
If you don't see any symbols chances are, it's probably an ionization smoke detector. Those alarms are sometimes marked with a letter I, or other symbols.
When you are taking a look at your smoke detector, please make sure to check the battery. That's crucial.
The bottom line: Smoke detectors do save lives. Adding a photoelectric smoke detector to your home will usually give you more warning in a slow-burning, nighttime fire.
