The Universal Security Instruments 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 smart alarm also offers protection against the silent killer - carbon monoxide - making it a 3-in-1 detector. The ideal addition for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes in every room.
This 3-in-1 smart alarm 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 alarm 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 Security Instruments 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.

Works fine easy to install
Instructions were easy, no battery changing is nice, and install was relatively easy. I'll probably be buying a second one.

Advanced technology and quality
I bought this alarm beacuse it was the only one rated on Consumer Reports rated to have both detection mechanisms - ionization and photoelectric.

3-in-1 Detector
Easy to install over existing mounting holes from my old smoke detectors. This had good directions. I like that it includes CO detection and both photoelectric and ionization fire detectors.

Smoke, Fire and Carbon Monoxide Smart Alarm
The USI Hallway 3 in 1 detector gives me piece of mind. The ten year battery makes it so I don't have to worry about dead batteries. I'm thinking I'm going to buy two more more our summer cottage.

Just What I've Been Waiting For
Just a couple of years ago, I don't think there existed a 3-in-1 detector that had photoelectric + ionization + carbon monoxide sensors to detect smoldering fires, larger fires, and carbon monoxide. Then I found out about this 3-in-1 detector when it was top-rated by Consumer Reports in its 2022 tests. I'm very happy. This is exactly what I've been waiting for. And it comes with a 10-year battery too! Perfect. I couldn't have been happier.

USI Hallway 3-in-1 Smoke, Fire and Carbon Monoxide Smart Alarm
I did a lot of digging and found these highly rated smoke, fire and carbon monoxide detectors in Consumer Reports. These will last 10 years with no battery replacement and are less than half the price of similar smart units that communicate with each other. I don't need the additional features an i love saving money!
