Can you mix ionization and photoelectric smoke detectors?
You can create the safest environment possible for your family by installing a mix of photoelectric and ionization smoke detectors. It’s too risky to go with one and not the other because there is no way to predict what type of fire threat your home may experience.
What is the difference between photoelectric and ionization 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”).
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.
How long do ionization smoke detectors last?
8-10 years
Next time you change the battery in your smoke detectors, be sure to check its age, as well. According to the U.S. Fire Administration, most alarms have a life span of 8-10 years. After this time, the entire unit should be replaced.
Which is the best type of smoke detector to use?
The bottom line is that ionization and photoelectric smoke detectors are each better at detecting distinctly different — yet potentially fatal — fires. And, since no one can predict what type of fire might start in the kitchen, the U.S. Fire Administration recommends that homeowners use both ionization AND photoelectric smoke detectors.
Which is better ionization or photoelectric smoke alarms?
The technology used in Ionization Smoke Detectors creates a delayed warning in smoldering fires which can lead to loss of life. Photoelectric Smoke Alarms are more effective at warning of smoke from smoldering fires and are less susceptible of nuisance alarms.
How can I tell if my smoke detector is ionization?
Most residences have smoke detectors installed before their inhabitants move in. To find out whether you have ionization, photoelectric or dual sensor alarms take the smoke alarm down from the ceiling or wall and inspect the back. You may want to find professional help to do this.
Can a smoke detector detect both Flaming and smoldering fires?
The SA320CN detects both flaming and smoldering fires because it has both the photoelectric and the ionization sensing technologies built in. The warning sound is loud enough at 85dB. It uses standard two AA batteries that are easily available. The battery door is so accessible and therefore replacement of batteries is never a hassle.
