Ionization smoke alarms tend to respond faster to the smoke produced by flaming fires than photoelectric smoke alarms. Photoelectric smoke alarms tend to respond faster to the smoke produced by smoldering fires than ionization smoke alarms.

Which smoke detector has least fake alarms?

Photoelectric smoke alarms sound tens of minutes faster than ionization smoke alarms during smoldering stage fires with significantly fewer false alarms. Furthermore, their performance in flaming stage fires is comparable to ionization alarms, making the photoelectric alarm the best choice.

What type of smoke detector is best for kitchen?

Photoelectric smoke detectors
Photoelectric smoke detectors are best at detecting the large particles typical of smoky, smoldering fires but poor at detecting fast, flaming fires. Photoelectric units are less prone to false alarms from burnt food, so they may be a better fit in kitchen areas.

Why is my smoke detector going off randomly?

The most likely reason smoke detectors go off unexpectedly is that people aren't changing the batteries in them often enough. In most sensors you might think of, the strength of the signal goes up when they detect what they're supposed to. Common causes of smoke detector false positives around the house.

How long do 9v batteries last in smoke detectors?

6 months
Testing and Changing Your Fire Alarm Battery If your smoke alarms are powered by a nine-volt battery, the battery should be replaced every 6 months, while the alarm itself should be replaced once every 10 years. For 10-year lithium-powered fire detectors, you won't need to replace the battery.

Should kitchens have a smoke detector?

But a smoke detector is important in any kitchen simply because fires often start there — even if you aren't around when they start. To minimize false alarms, detectors should be mounted at least 10 feet from the stove or oven. In a small kitchen, this may be difficult.
