We purchased and evaluated the top 10 photoelectric smoke alarms on the market for our comprehensive review. With so many factors at play, evaluating the best smoke alarms on the market can be difficult. In our research, we evaluated key attributes, such as smoke sensitivity, alarm volume, and battery life. We ran each model through its paces in our lab, recording the results from these tests to provide you with a straightforward guide with which to choose the best smoke alarm for your home.

Most homes in the US have more than one smoke alarm - they are a vital component of your fire protection plan. Knowing which alarm to buy might depend on your needs and requirements. For example, if you have pets or small children, you will likely have an alarm that detects both smoke and fire. If you are avid barbecuers, consider investing in a smoke alarm with a photoelectric sensor - they are designed to provide more thorough detection for barbecue smoke.

First Alert BRK 3120B Hardwired Photoelectric Ionization and Smoke Alarm with Battery Backup

by First Alert

Photoelectric and ionization sensors provide comprehensive fire detection

The BRK 3120B is one of the best hardwired smoke alarms we've tested, and it easily beats out our previous top pick, the Kidde KN-COSB. The BRK 3120B is easy to install, and offers more protection than the Kidde KN-COSB. It has a dual photoelectric and ionization smoke sensor, which makes it more quickly than the Kidde KN-COSB at detecting both fast burning and smoldering fires. The BRK 3120B is also the first photoelectric and ionization smoke alarm we tested that emits a T3 pattern, which tests faster and better for detecting slow smoldering fires than the standard s-shaped pattern. The BRK 3120B has a dual alarm feature, so the alarm will sound if either smoke sensor detects smoke. The BRK 3120B also has two latching features, which indicate a low battery or the originating alarm in a system. The BRK 3120B has a dual voice warning feature, which alerts you when the alarm sounds with a loud, sharp sound. The BRK 3120B is also the first photoelectric and ionization smoke alarm we tested that's equipped with a battery backup, so in the event of a power failure, it will still sound an alarm. The BRK 3120B is easier to use than the Kidde KN-COSB, and doesn't require a Kidde KN-COSB battery. The Kidde KN-COSB also requires you to replace the battery every six months, and the BRK 3120B requires no battery replacement. The BRK 3120B also has a longer battery life than the Kidde KN-COSB. The Kidde KN-COSB has a battery life of 10 years, and the BRK 3120B has a battery life of 20 years. The Kidde KN-COSB also costs more than the BRK 3120B, costing $68 compared to $45 for the BRK 3120B.

Smoke Alarm,Photoelectric Smoke Alarm with UL Listed, Battery Operated Smoke Alarm (Battery Included), Fire Safety for Home (1)

HSTMYFS Smoke Alarm

by Brange

Easy Install and UseThe alarm can easily install.

The 1-8 Smoke Alarm from First Alert is a solid, reliable, and affordable smoke detector that packs lots of power into a relatively small package. The alarm is loud enough to wake you up at night, and it has a warning light that flashes red when smoke is detected. The alarm has two modes: a sensitivity mode, which detects smoke at all frequencies, and a hush mode, which decreases the alarm to a whisper volume. Both modes are very effective. On the downside, the alarm lacks a silence button, so you can't silence it when you accidentally set off the alarm. The alarm also lacks a built-in carbon monoxide detector, which is a common feature in smoke detectors, but it's easy enough to add one using an included plug-in CO detector. In tests, this detector consistently detected smoke from burning candles and paper, and it's immune to common false alarms, so it's a great choice for a home alarm.

X-Sense Smoke Detector Alarm, 10 Years Battery-Operated Smoke and Fire Alarm with Photoelectric Sensor, Compliant with UL 217 Standard, SD06 (Not Hardwired)

X-Sense Smoke Detector Alarm

by X-Sense

EASY INSTALLATION: Requires no rewiring; easy to mount on any wall or ceiling with the included mounting bracket, screws and anchor plugs

The X-Sense SD06 is our favorite photoelectric smoke detector because it features the best of all worlds: it's the only photoelectric smoke detector we tested that is also battery-powered (the others run off of hardwired power), and it has the longest battery life (up to 10 years). The alarm's self-activation feature is also a huge plus, as it's the only photoelectric smoke detector we tested that doesn't require manual activation (the others do). The SD06 is also the most easy to use of the photoelectric smoke detectors we reviewed; simply place it in the mounting bracket (which comes with it), and the alarm will automatically activate when it's installed. The SD06's photoelectric sensor is very sensitive, and it's able to respond faster to all fire types in one alarm, minimizing false alarms. The alarm's multi-colored flashing LED indicator makes it easy to tell if the alarm is working properly, and its 85-decibel alarm sounds loud enough to be heard in any room, without showing any visual indications (unlike the Kidde KN-COSB-12A). The alarm's built-in battery lasts for 10 years, making the alarm maintenance-free. The SD06 also has the added benefit of a built-in digital calendar, which displays the current date and alerts you of any upcoming or past alarms. The alarm's 10-year battery life also makes it "future-proof," as the SD06 will continue to work well past 10 years. The SD06 is more expensive than the Kidde KN-COSB-12A, but it's well worth the extra money, as the SD06 has the best performance of any photoelectric smoke detector we reviewed, and it's the only photoelectric smoke detector we tested that is also battery-powered.
