Why You Should Trust Us

We spoke to a number of people in the fire-safety industry: Joseph Keenan, assistant fire marshal of the Burlington Fire Department Judy Comoletti, division manager for public education at the National Fire Protection Association John Drengenberg, consumer safety director at UL Timothy Sendelbach, editor-in-chief of Firehouse Magazine, who has 30 years of experience in fire and safety services and Tom Kiurski, training coordinator and director of fire safety education for Livonia, Michigan, as well as a columnist with FireRescue1. Kiurski has 35 years of experience in the fire services.

In addition, we spent hours reading hundreds of pages of smoke-alarm studies, such as the NFPAs massive Smoke Alarms in U.S. Home Fires report, the National Center for Healthy Housings Evaluation of the 10-Year Smoke Alarm Project report , and Vision 20/20s The Smoke Alarm Problem report , among many others. Note that the National Center for Healthy Housing is partially funded by The Home Depot Foundation.

One Chirp Per Minute#

If you get one low volume chirp every minute, that is a sign of a problem with the battery. Replace the dry cells if they have been in use for more than 12 months.

For users who recently replaced their batteries but hear a chirp every minute, check that the batteries are facing the right direction. If you insert batteries with the contacts facing the wrong path, you may hear the chirp, and your smoke alarm will not work. Another reason why you may face this problem is leaving the battery drawer open after changing the batteries. Make sure you check, and if it is still open, close it. If the above does not work, you can try resetting the unit.

    Also Great: First Alert Pr710 Slim Photoelectric Smoke Alarm With 10

    *At the time of publishing, the price was $21.

    Many states and municipalities require smoke alarms with 10-year batteries. For these areas, we recommend the First Alert PR710 Slim Photoelectric Smoke Alarm with 10-Year Battery, which, as its full name indicates, has a photoelectric sensor and a fully sealed 10-year lithium-ion battery. The alarm has a low profile from the wall of about an inch, and it honestly looks a lot more streamlined than our main pick . It typically costs around $25, making it a relatively inexpensive option. For roughly a few dollars more, First Alert sells a similar model with a pathway light that turns on when the alarm activates.

    One purported benefit of the sealed battery is that it offers a higher degree of tamper resistance because it is not removable. But one important thing to understand is that when you take the alarm unit off the wall, it deactivates.

    Even though this alarm is sold with a 10-year battery, it still requires testing on a regular basis. A study performed for the Centers for Disease Control and Prevention did a long-term follow-up on alarms and found that 14% of those using lithium-ion batteries had dead batteries before the full 10 years were up.

    Our Pick: First Alert Sa511cn2

    For your primary line of defense, we recommend the First Alert SA511CN2-3ST Interconnected Wireless Smoke Alarm with Voice Location. This is a photoelectric alarm, so its effective against both slow-burning, smoldering fires and fast-burning, flaming fires. Its sold in a two-pack, and the two units link together through a wireless signaland can combine with additional unitsso that they all sound at once. In addition, you can preset each unit to a location so that when an alarm goes off, all of the units indicate which room the fire is in. The alarm is a voice alarm, which research indicates is more effective in waking small children than a simple tone. The First Alert SA511CN2-3ST is the only alarm we found that combines the voice alarm, the location feature, and the wireless connection all in one unitat a price thats merely on the high side of average for the category.

    Because theyre interconnected, the SA511CN2-3ST alarms not only give you an early warning but also tell you where the problem is originating from. During initial setup, you assign each alarm a room location. When the alarms go off, they all announce the source alarms location. As training coordinator and fire safety educator Tom Kiurski told us, Vocal smoke alarms are recommended if you have children between 4 and 12 years of age, because studies show they respond better to a familiar voice, as opposed to something that can fall under white noise.2

    *At the time of publishing, the price was $8.

    To have the most complete fire-detection system, we recommend adding a First Alert SA303CN3 Battery Powered Smoke Alarm to each floor. This model is an ionization alarm, so its designed to be better than our other picks at detecting a fast, flaming fire. Its not as good as the others at detecting smoky fires, however, so we dont recommend it as a primary alarm. According to our research, ionization alarms are also prone to nuisance alarms, particularly from shower steam or cooking smoke, so make sure to place them accordingly.

If you dont already have CO alarms, we strongly recommend including a few First Alert SCO501CN-3ST Combination Smoke and Carbon Monoxide Alarm with Voice Location units in your interconnected system.

That CO detector adds a good bit to the pricecurrently a single SCO501CN-3ST unit is just barely cheaper than the two-pack of our top pickso we made this model a separate recommendation in case youre already covered with a stand-alone CO detector.

    Know Your State And Local Laws

    Its important to understand your state and local smoke alarm regulations before making a purchase. We found that many regulations are at odds with one anotherand with our recommendations. No company sells a one-size-fits-all smoke alarm capable of satisfying the requirements of every state.

    For example, our main recommendation, the First Alert SA511CN2-3ST Interconnected Wireless Smoke Alarm with Voice Location, uses two AA batteries, but many states now require models with 10-year sealed batteries. We have a recommendation to meet that requirement, as well.
