Generally, there are two types of home smoke alarms: photoelectric and ionization .
How do I know what kind of smoke detector I have?
If you are unaware which type of smoke detector you have in your home, now is the time to check. You can do so by taking the smoke alarm down and look at the back for either “Photoelectric” or “Ionization ,” or a symbol with the letter “P” or “I” on the back.
What are the 3 types of smoke detectors?
There are three types of smoke alarms, ionization, photoelectric and a combination of the two which is commonly called a “dual” detector.
What type of smoke detector is best?
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.
What is the difference between ionization and photoelectric smoke detectors?
Ionization smoke alarms are generally more responsive to flaming fires . ... Photoelectric smoke alarms are generally more responsive to fires that begin with a long period of smoldering (called “smoldering fires”).
Why are ionization smoke detectors banned?
The problems with ionisation technology
Whilst perfectly safe to residents, ionisation fire alarms are banned in several countries as they contain small quantities of radioactive material (Americium 241) meaning there are storage and disposal issues.
What type of smoke alarm is best for bedrooms?
Product Details. According to the NFPA, smoke alarms should be placed in every bedroom, outside each sleeping area and on every level of your home. In addition, industry experts recommend having both photoelectric and ionization alarms for optimal protection against flaming and smoldering fires.
Should smoke detectors be on wall or ceiling?
Smoke alarms should be installed at least 10 feet (3 meters) from a cooking appliance to minimize false alarms when cooking. Mount smoke alarms high on walls or ceilings (remember, smoke rises). Wall-mounted alarms should be installed not more than 12 inches away from the ceiling (to the top of the alarm).
Do all smoke detectors have the same plug?
The key is knowing what connector your smoke detector has so that you buy a new smoke detector with the same connector . In fact, some smoke detector companies will give you an adapter you can use to connect both commonly used connectors to a new smoke detector.
Can smoke detectors detect vape?

Are 10 year smoke detectors good?
Smoke alarms have a limited lifespan. The National Fire Protection Association (NFPA) recommends every smoke alarm be replaced after 10 years and that regular batteries be replaced every six months. With 10-year sealed battery alarms, battery replacements and late-night battery chirps are eliminated for a decade.
Do hardwired smoke detectors have to be the same brand?
Absolutely ! You can mix and match hardwired First Alert, BRK, and Onelink models. All of our current models use the same wiring harness and connector. We do not recommend mixing different brands since we can only guarantee the performance of First Alert and BRK alarms.
Do fire alarms detect carbon monoxide?
Combination smoke and carbon monoxide alarms have sensing technologies that work together to detect fires and the odorless, colorless, tasteless gas known as CO – the silent killer.
Are ionization smoke detectors safe?
There is no health threat from ionization smoke detectors as long as the detector is not damaged and used as directed. Do not tamper with your smoke detectors, as it could damage the shielding around the radioactive source inside of them.
