Are photoelectric smoke detectors the best?
For slow, smoky, smoldering fires, photoelectric alarms are far more sensitive and effective than ionization alarms.
What is the advantage of a photoelectric smoke detector?
Photoelectric smoke alarms are generally more responsive to fires that begin with a long period of smoldering (called “smoldering fires”). How they work: Photoelectric-type alarms aim a light source into a sensing chamber at an angle away from the sensor.
Are photoelectric smoke detectors better for kitchen?
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 smoke detector do firemen recommend?
Since no one can predict what type of fire might start in their home, the USFA recommends that every home and place where people sleep have: Both ionization AND photoelectric smoke alarms. OR. Dual sensor smoke alarms, which contain both ionization and photoelectric smoke sensors.
Should I install ionization or photoelectric smoke detector?
The NFPA acknowledges that a well-designed photoelectric alarm will usually outperform ionization alarms in all fire situations, regardless of type and material. During smoldering fires, ionization alarms failed to give sufficient egress time more frequently than photoelectric alarms failed to do so.
Do photoelectric smoke detectors have more false alarms?
They are also more prone to nuisance false alarms from ordinary cooking and steam from showers. Photoelectric smoke alarms sound tens of minutes faster than ionization smoke alarms during smoldering stage fires with significantly fewer false alarms.
Which type of smoke detector would be best to install?
For the best protection, both types of alarms or combination ionization-photoelectric alarms, also known as dual sensor smoke alarms, are recommended.
Where should photoelectric smoke detectors be placed?
Smoke detectors are typically placed on the ceiling because smoke and heat rise. Manufacturers recommend that ceiling-mounted detectors be placed at least 4 inches away from the nearest wall. If ceiling placement is impossible, it should be placed on the wall between 4 and 12 inches from the ceiling.
Is Kidde or First Alert better?
First Alert has better features than the Kidde because of the alarm system with a verbal warning of the threat.
Why does my photoelectric smoke alarm keep going off?
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.
Do you really need to replace smoke detectors every 10 years?
Maintain your alarms Because alarm sensors wear out, replace each alarm at least every 10 years. Also, alarms have labels showing when they were made. If you don't see a label, the alarm is old and must be replaced. Dust and cobwebs make it harder for alarms to detect smoke.
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.
Which is better hardwired or battery operated smoke detectors?
Once installed, though, hardwired smoke detectors are better than their battery-powered counterparts in every major aspect—safety, efficiency, maintenance and compliance with local codes.
Do photoelectric smoke detectors detect cigarette smoke?
Photoelectric smoke alarms (also known as optical smoke detectors) are most responsive to fires that begin with a long period of smoldering, such as when smoking materials like cigarettes are left unattended.
Where should photoelectric smoke detectors be placed?
Install smoke alarms inside each bedroom, outside each sleeping area and on every level of the home, including the basement. On levels without bedrooms, install alarms in the living room (or den or family room) or near the stairway to the upper level, or in both locations.
How long does a photoelectric smoke detector last?
8-10 yearsAccording 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. Most alarms have the date of manufacture inside the unit. If you cannot find the date, replace it.
What is a dual smoke detector?
Some smoke detectors utilize both ionization and photoelectric technologies. These types of smoke detectors are known as “dual” smoke detectors and are widely available at home improvement stores and online at a variety of price points and from several brands.
What is the best way to detect smoke?
This device aims a focused light source into a sensor chamber; when smoke enters the chamber, it reflects light, which then triggers the alarm. Photoelectric smoke detectors are best at detecting large smoke particles from slow, smoldering fires.
What happens when smoke enters the ionization chamber?
If smoke enters this chamber, the ion flow is disrupted and the alarm sounds.
Why is it important to detect smoke early?
Being able to detect smoke early can be a lifesaver, helping families to escape before the flames have even started and prior to potentially life-threatening smoke inhalation. These types of fires often occur when small flames from things like candles or cigarettes are left unattended.
Does Aire Serv install smoke detectors?

Is it safe to use a smoke detector with photoelectric?
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. Some smoke detectors utilize both ionization and photoelectric technologies.
Do ionization smoke detectors work faster?
Ionization smoke detectors respond faster to smoke from flaming fires than a photoelectric device does. Most flaming, fast-moving fires are a result flammable liquids, wood, or paper catching fire. These are items that produce flames right away and do not have as much smoke as a smoldering fire.
Are Photoelectric Smoke Detectors Better?
There can be a smoldering fire. There can be a large number of flaming fires in a home fire outbreak. It can happen in broad daylight or at night. You cannot decide the time or type of fire. Thus whatever smoke alarm technology you are using must have its excellence in predicting both types of fire perfectly. Only this can make you aware of a fire in its early stage and save your life even if you are awake or asleep.
Should You Have a Photoelectric Smoke Detector?
