A house fire is scary. A properly functioning smoke alarm and early detection is an important (and perhaps most important) factor in keeping you and your loved ones safe.

These sirens are available in two packs and can be linked together to sound simultaneously. They will also tell you in which room the fire started.

Similar to our selection, but also equipped with a carbon monoxide alarm, these photoelectric smoke alarms with voice warning can be connected and allow you to detect threats by location.

The SA303CN3 Early Warning is slightly better than our other picks in detecting fast-burning fires, but it’s generally slow to start and is best used as an additional part of the system.

The PR710 isn’t as compact as our options, but it does come with a 10-year sealed battery, which is required by some states and municipalities.

Best Smoke Detectors Of 2024

After reading over 70 hours of fire safety research, interviews with five experts, and over 100 pages of smoke alarm information, we recommend the First Alert SA511CN2-3ST Wireless Smoke Alarm with Voice Remote as an effective first alarm system. Whole house fire protection system.

The UL Listed First Alert SA511CN2-3ST Siren comes in a two-pack and these units (and other units) can be linked together so that when one sounds, they all sound, giving you more time to identify and resolve the problem. . This wireless connection setup is internal to the siren and does not require a phone app. You can also specify each unit by location, so that when the alarm is activated, all units will show the room where the accident originated from. The First Alert SA511CN2-3ST is the only model that combines all these features into one bundle, and at a price that is slightly above average for the class, it is an excellent value. Also, the experts we spoke to told us that because it has a voice alarm instead of a buzzer or an alarm, it is possible to wake up sleeping children.

If you’re shopping for a smoke alarm and don’t already have a carbon monoxide alarm installed, we recommend the SCO501CN-3ST Combination Alarm and Carbon Monoxide Alarm with Voice Zone on Every Floor. This electric alarm is our first choice along with a carbon monoxide alarm that can detect carbon dioxide from a damaged or leaking chimney or fuel burning device (such as some stoves, dryers, or water heaters). This feature adds significantly to the price, with single units often costing slightly less than our top two-pack options.

For a more efficient smoke alarm system, we also recommend adding a SA303CN3 battery operated smoke alarm on each floor. This alarm uses a different detection technology – ionization – so it’s a little better at detecting fires burning faster than our other options. It is not as good as a photo alarm to detect slow, smoke, fire, and in studies, the ionization alarm goes off after some important minutes, which is why we recommend using them as a supplement rather than as a main system alarm. .

We recommend AA or 9V batteries for smoke alarms, but if your city or state requires a 10-year sealed battery for smoke alarms, we like the PR710 Slim Photoelectric Smoke Alarm with 10-year battery. It’s UL-listed, so it doesn’t have the home protection of our top pick, but otherwise it should offer the same smoke-sensing benefits. Research has shown (PDF) that a 10-year battery doesn’t actually last 10 years, so we still recommend testing as prescribed and not getting satisfaction. First Alert P1210E 10 Year Battery Photoelectric Alarm with Safety Road Light is sold in a slim profile, which is the same alarm but adds a road light that turns on when the alarm is activated.

We interviewed several people in the fire safety industry: Joseph Keenan, Deputy Fire Chief, Burlington (Vermont) Fire Department; Judy Comolletti, Manager, National Fire Protection Association (now retired); John Drengenberg, Director of Customer Security, UL; Timothy Sendelbach, editor-in-chief of Firehouse magazine, with 30 years of experience in fire and security operations; Tom Kirsky is a training provider and director of fire safety education for the city of Livonia, Michigan and author of FireRescue1. . Kiurski has 35 years of firefighting experience.

In addition, we spent hours reading hundreds of pages of smoke alarm research reports, such as the NFPA’s major report “Smoke Alarms in US Home Fires” and the National Institutes of Health’s “‘Ten Years of Expertise'” report. Expertise” (PDF). , Vision 20/20’s “Alarming Problems” report (PDF), and much more. Note that the National Institutes of Health is part of the National Depot Foundation.

Working smoke alarms are important in any home, but you should consider them as part of a comprehensive fire safety plan. Your plan should include other safety features such as fire extinguishers and escape routes, but most importantly, your plan is based on understanding what to do in the event of a fire. Timothy Sendelbach of Firehouse Magazine told us, “The best advice I can give is to do fire drills, use the test button on the alarm, and familiarize the family with the sound and advice to do in the event of an emergency.” is being played.” For more information, we recommend NFPA’s page on how to develop a home fire escape plan.

It is important to know your state and local smoke alarm laws before purchasing. We have found that many laws are not compatible with our recommendations. No company sells smoke alarms that meet every state’s requirements.

For example, our top recommendation First Alarm SA511CN2-3ST integrated wireless smoke alarm uses two AA batteries in place of the buzzer, but most states now require models with sealed batteries for 10 years. We also have recommendations to pay for this need.

The First Aid website has a great interactive map to help you understand your state’s requirements. We also recommend contacting your local fire department for more information in your area.

There are two types of smoke alarms: photoelectric and ionization alarms. Each detection technique has its advantages, and as the training supervisor and fire safety teacher Tom Kiurski told us, “I recommend using two types in your home.” This is also the official position of NFPA and UL (PDF).

When smoke enters the alarm, the photo sensor is activated and deflects a beam into the photocell. For slow, smoking, fire, photo alarms are more sensitive and effective than ionization alarms. They are a little less effective in detecting flammable flames, but the difference in performance is enough to lean toward the imaging model as our first choice and the ionization model as an additional alarm.

Ionization alarms are inexpensive and good at detecting small particles in fast flames, but they are ineffective against smoky, fiery fires. Ionization alarms contain a small amount of radioactive material (americium-241) that ionizes oxygen and nitrogen in the air, a process that creates a small electron in the hearing chamber. An alarm monitors this current and when smoke enters the room, the electricity is cut off and the alarm sounds.

Many studies have quantified the difference in response time between two types of stimuli. The Dallas-Fort Worth NBC affiliate placed separate smoke alarms 15 feet apart to simulate a fire in a smoky couch. Two photo alarms sound at just 20 minutes, and two ionization alarms sound at 22 and 28 minutes. By the time the second ionization alarm sounds, the fire is in the “complete burn stage” could not survive,” said the fire chief who oversaw the investigation.

For fast-burning flames, a study (PDF) by UL and the Fire Protection Research Foundation found that an ionization siren responded an average of one minute faster than a photoelectric siren. It may not seem like much, but a home can reach “unsustainable conditions” in less than three minutes.

This was revealed in a survey conducted by the National Institute of Standards and Technology (PDF). In rapid fire, you have very little time to escape, so this time is very important for your survival. As John Drengenberg, director of consumer safety at UL, told us, “You never know what kind of fire is going to happen.” In other words, ionization alarms play an important role in the overall process.

Considering that both types of sensors have their advantages, you can decide that a dual-technology siren with a photoelectric and ionization sensor in one is the best choice. But there are good reasons not to rely solely on these compound warnings. Ionization sensors are prone to noise, mostly from cooking and shower steam, and people often turn them off because of this concern. However, Joseph
