July 22, 2024Three in one 10 year battery smart alarm
The product arrived promptly in excellent condition. It was easy to fix. Previously, I had wired three in one 10 year battery alarm which will show a red and green light. But the current one does not have that feature. The new one blinks red once every three or four minutes. The previous one blinks every two minutes. It will be better if the new one had the same green and red light so that we know the alarm is alive. But the new one works well. I know it is alive by looking at its regular blinks.

I purchased two of these alarms for my new home. This product detects both fast burning and smoldering fires as well as CO. Product was delivered quickly and was easy to install.

April 13, 20233-in-1 Smoke, Fire & CO Smart Alarm
As a retired firefighter I was happy to find this product in a review from Consumer Reports. These units cover the major concerns of every home owner. And finding that they are less expensive from the manufacturer than from Amazon was an extra plus. I received them in a timely manner.

October 29, 2022So far so good
Easy to install. Pull tab to activate is convenient. Purchased because this is one of the few 3 in 1 alarms available photoelectric for smoldering fires, ionization for flaming fires, and carbon monoxide, and it was recommended by Consumer Reports.

I was looking for a combo smoke/fire/CO alarm with 10 year sealed battery and found this one on a “best†list. Bought it here as the 6 pack was convenient and reasonably priced. Easy to install.

I own an 8ncome property having approximately 20 smoke-carbon units. Done are hard-wired , others not. I intend to continue replacing defunct units with the USI product line. I'm pleased with the value, product line and customer service.

The USI MIC3510SB 3-in-1 Smoke, Fire and Carbon Monoxide Smart Alarm provides 10 years of continuous protection against deadly threats in the home. New patented Universal Smoke Sensing Technology provides the benefits of both photoelectric and ionization alarms in one device to protect against fast flaming and slow smoldering fires. This USI Electric Smoke and Carbon Monoxide Detector also offers protection against the silent killer - carbon monoxide - making it a 3-in-1 alarm. The ideal addition for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes in every room.
This smoke and carbon monoxide detector utilizes a sealed battery (included) that will never have to be replaced throughout the life of the detector, giving you a decade's worth in peace of mind even in the event of a power outage. Permanent Power also saves money from battery replacements (up to $38.00 over the 10-year life of the alarm), eliminates annoying low battery chirps and helps the environment by reducing environmental waste from disposed batteries. This USI electric smoke detector features microprocessor intelligence to completely eliminate nuisance alarms, a single silence/test button to quiet a non-hazardous alarm and an end-of-service life warning that sounds when it's time to replace the alarm (approximately 10-years from activation).
This USI Combination Alarm conforms to UL217 and UL2034 standards. It is also California State Fire Marshal approved and Federal Housing Authority (FHA) approved to exceed industry standards. The Universal Electric MIC3510SB 3-in-1 Smoke, Fire and Carbon Monoxide Smart Alarm comes with a 10-year limited warranty that covers both the alarm and battery.
