Description

Featuring a low-profile, contemporary design, the First Alert PR710 Slim Photoelectric Smoke Alarm with 10-Year Battery provides the same protection as a standard smoke alarm while taking up only a fraction of the space. This slim, battery-operated smoke alarm requires no hardwiring for installation, making it an ideal solution for those who want to enhance fire safety without hiring an electrician. It features a built-in 10-year lithium-ion battery that provides continuous power for up to a decade. Equipped with an ultra-reliable photoelectric sensor, the smoke alarm detects smoke from slow-burning, smoldering fires while keeping false alarms to a minimum. A patented smoke entry system further enhances the detector's reliability by providing a direct path to the smoke sensor. The simple twist-lock mounting system installs easily onto a wall or ceiling, while the tamper-resistant locks help prevent removal of the battery to keep the alarm secure. Half as thick as a standard alarm, the smoke detector has a sleek, slim design that blends in seamlessly with most decor. A loud 85-decibel alarm sounds when smoke is detected, and a convenient test/silence button lets you easily check alarm function and mute false alarms.

  • Feedback after eight years of use
Size: 1-Pack Style: Standard Detection Pattern Name: PR710
05/2026 Update - Not a single one of the four of these I purchased lasted "10 years" best we got was 3-4 years. Anyone buying this with the belief that it will last 10-years is setting themselves up for disappointment. 2/21/18 Update - I purchased two of these detectors for bedrooms. The rest of our home has AC powered alarms. Twelve days past the return window, one detector started acting goofy and going off frequently for no reason. The alarm was in a bedroom, so it was obviously the worst possible spot for that issue. I had to take it down in the middle of the night just so my teenage daughter could get some sleep for school. I'll contact the manufacturer for assistance but if you're considering purchasing this alarm, heed the large number of low rating reviews that are based on the new number of unacceptable false alarms. I'm now regretting I didn't do so. Like most people, I tend to think "oh, that probably won't happen to me". Well, it did. Now I have to either order a new type of detector or try to get the faulty one replaced through the manufacturer's warranty. Being forced to replace an item purchased only 42 days ago is very annoying. I'll probably just toss it and buy a Kidde. I have a sealed 10-year battery model Kidde in my bedroom similar to this First Alert and the Kidde has been rock-solid for well over a year with zero false alarms. Original review follows I purchased two of these for rooms without AC wired detectors. Both installed very easily and functioned fine when tested. The slim profile helps keep them from sticking out or distracting from the appearance of the room. The alarm is loud but not as loud as our wired detectors or even some other battery operated detectors I've tried. It has a test button but no hush button. It is definitely loud enough to wake and alert if activated. I like the sealed 10-year battery and the fact that it doesn't require frequent changing like battery operated detectors. However, I make sure to test it frequently and not take for granted it will automatically last ten years. ... show more

  • No more cooking alarm....
Size: 1-Pack Style: Standard Detection Pattern Name: PR710
When we moved into our house, the previous tenants had installed a ionization type smoke detector. It would go off if the oven was opened, or the stove got too smoky from frying something. I did some research, and found that photoelectric style are not as trigger happy as ionization types around the kitchen. This model had good reviews, and didn't need battery replacement. ... show more

  • Great with moderate issues
Size: 1-Pack Style: Standard Detection Pattern Name: PR710
I picked up the First Alert Slim Smoke Alarm (PR710) because I wanted something that looked clean on the ceiling and didn’t require constant battery changes. The slim design is definitely a win—it’s way less bulky than the old alarms I had. Installation was super easy too. I just twisted it into the bracket and that was it. The 10-year sealed battery is a huge plus since I don’t have to worry about swapping out batteries every year. And knowing it uses a photoelectric sensor for smoldering fires gave me some peace of mind. That said, I’ve had a couple of false alarms go off in the middle of the night, which was pretty frustrating. Also, a friend of mine who bought the same model said theirs started beeping low battery after just a few years, even though it’s supposed to last a decade. One other small gripe—if you’re replacing an older First Alert alarm, the mounting plate might not match, so be ready to adjust. Overall, I like the look and simplicity of this alarm, but I’m keeping an eye on its long-term reliability. ... show more

  • No more changing batteries.
Size: 1-Pack Style: Standard Detection Pattern Name: PR710
I recently purchased the First Alert Slim Photoelectric Smoke Alarm with a 10-Year Sealed Battery, and I couldn't be more pleased with this essential safety device. First and foremost, the convenience of a 10-year sealed battery is a game-changer. No more worrying about changing batteries annually or dealing with annoying low-battery chirps in the middle of the night. The long-lasting battery ensures continuous protection for a full decade, providing peace of mind and hassle-free maintenance. The slim and compact design of this smoke alarm is another notable feature. It blends seamlessly with my home's decor, and its unobtrusive profile doesn't draw too much attention. Installation was a breeze, thanks to the included mounting bracket, screws, and clear instructions. It's an ideal choice for those looking to keep their living spaces safe without compromising aesthetics. ... show more
