Is a photoelectric smoke detector better?
It’s safe to say that every home should have a photovoltaic smoke detector. While ionizing smoke detectors have proven to be more effective at detecting wildfires, photovoltaic alarms outperform them when it comes to smoldering fires.
What is a photoelectric smoke detector?
The photoelectric smoke detector consists of a light-emitting diode and a light-sensitive sensor located in a sensor chamber. The presence of smoke particles suspended in the chamber scatters the light beam. This diffused light is detected by a photosensitive sensor which triggers the alarm.
Where do you place photoelectric smoke detectors?
According to the NFPA, smoke alarms should be placed in every bedroom, outside every bedroom, and on every level of your home. Additionally, industry experts recommend having photovoltaic and ionizing alarms for optimal protection against flames and smoldering fires.
How long do photoelectric smoke detectors last?
Most smoke alarms have a lifespan of eight to ten years and replace the batteries every year. A smoke detector with a lithium battery or a wired smoke detector can last 10 years, and then you just replace the whole device. Carbon monoxide detectors last between five and seven years.
Should I buy an ionizing or photoelectric smoke detector?
Ionizing smoke detectors tend to react more quickly to smoke produced by wildfires than photoelectric smoke detectors. Photovoltaic smoke detectors react more quickly to smoke produced by smoldering fires than ionizing smoke detectors.
Do photoelectric smoke detectors detect cigarette smoke?
Yes, smoke detectors can even detect cigarettes as they produce smoke and any smoke found by the smoke detector will be extinguished if it is turned off. Although smoke detectors can detect cigarette smoke, they cannot always detect it if it is too weak. A good smoke and carbon monoxide detector would be Nest Protect.
Which smoke detector is better optical or ionizing?
While ionization sensors generally respond faster to “burning” fires, optical sensors will almost certainly respond faster to “smoldering” fires. Ionization is more sensitive than the two and will provide early warning of an impending fire.
Do I need a photoelectric smoke detector?
It’s safe to say that every home should have a photovoltaic smoke detector. While ionizing smoke detectors have proven to be more effective at detecting wildfires, photovoltaic alarms outperform them when it comes to smoldering fires.

What is the difference between ionization alarms and photoelectric smoke?
Ionizing smoke detectors are the most common smoke detectors and are fastest when you sense flame, the rapid movement of fires. They are faster in detecting smoldering fires than ionizing smoke detectors. The photoelectric smoke detector consists of a light-emitting diode and a light-sensitive sensor located in a sensor chamber.
Where should smoke alarms not be placed?
Do not locate smoke alarms within 3 feet of the stove or air conditioner, return grilles or registers. Do not place them in areas with turbulent air, where the airflow may prevent smoke from reaching the detectors.
How much does a photovoltaic smoke detector cost?
The basic ionizing alarm can be very inexpensive – starting at under $10. The special model may be closer to $50. Photovoltaic alarms can be found for less than $20, but can cost up to $100. Most smoke detectors need to be changed. every 10 years.
What type of smoke detector is best for the kitchen?
Photoelectric smoke detectors are best at detecting large particles, typical of smoldering smoke fires, but weak at detecting fast flames. Photovoltaic modules are less susceptible to false alarms than burnt food, so they can fit better into kitchens.
