Question: I have heard that there are two different kinds of detectors, but I forget which type is supposed to be best.What are my choices, and what kind should I use?

Answer: Two different technologies are used to detect smoke: an ionization detector senses charged particles called ions. The photoelectric kind detects a reduction or reflection of light when smoke flows between a light beam and a sensor. The ionization type is the most common; some detectors combine both methods.These combination detectors are probably the most effective, though either type by itself will provide you with sufficient warning to escape a fire.Both types of devices must pass the same test to be certified as UL-listed smoke detectors.Ionization detectors respond more quickly to flaming fires with smaller combustion particles; photoelectric detectors respond more quickly to smoldering fires.

Question: Sometimes when I’m cooking, a detector near my kitchen goes off.How can I prevent that?

Answer: Whether you have an ionization or a photoelectric type detector, steam or high humidity can lead to condensation on the circuit board and sensor, causing the alarm to sound.Some detectors have a button that will shut them off for a few minutes, usually long enough for the steam and smoke generated by cooking to dissipate. Or you could relocate your present detector away from the kitchen.

Question: I read recently that some people died in a house fire even though they had working smoke detectors.How is that possible?

Answer: In some cases people who have escaped a burning house after the alarm sounds will attempt to run back inside and retrieve belongings.Often those who re-enter a burning building fall victim to toxic smoke and hot gasses before they get very far.That’s why I recommend that once you are clear of a burning building, don’t go back inside for any reason.

Question: How often should I change the batteries in my smoke detector?

Answer: Twice a year, or sooner if you hear an intermittent beep that signals the need for a new battery.I recommend changing the battery in the spring and fall, when you change your clocks for Daylight Saving Time.

Question: How long do smoke detectors last?

Answer: It’s a good idea to replace them every ten years.
