June 14, 2023You won't be sorry!
I am replacing all of our smoke alarms with the 2-in-1 Smoke and Fire Alarm. These will allow us to rest easy knowing the batteries can't be removed and they will sense both smoke and fire.

As a landlord I appreciate the sealed battery. Less chance of someone removing the battery to use in something else. I am very satisfied with the quality of the product and I will certainly purchase this product again when needed.

April 22, 2022I bought these to bring our home up to the standards set for our home before we put it on the market. Liked that I could get a muti-pack of 6 at a great price. I hope the new owners will have a safer place to live with the 2 types of smoke detection.

Easy to install over existing mounting holes from my old smoke detectors. This had easy to follow directions. I like that it includes both photoelectric and ionization fire detectors. I have 5 of these installed,

March 4, 2022An excellent life saver
Was smelling smoke in my unit so I called local fire dept. to check it out. Turned out, my hvac needed replacing and while firemen were here, they checked out my smoke alarm & decided I needed a better, newer one….and free of charge they installed this one and suggested buying an additional smoke alarm for my bedroom, so I purchased this one the next day! What better recommendation can you get than from City Firemen? ðŸ‘ðŸ‘ðŸ‘

February 26, 2022So far, so good
Used this style to cover areas in my home that were not already hardwired. Installed easily with minimal tools. 6 months and no problems. Time will tell.

September 28, 2021Pleasantly surprised.
It was difficult finding a 2-in-1 smoke and fire alarm in the stores where I live to replace my 10 year old unit. So I decided to go on line to search but the reviews of the few I found were poor. And then I found UI. The reviews on this detector were outstanding. I was a little leery because of the low price compared to the competition, but I thought I would take a chance. The unit shipped and arrived just days after ordering it. It was very easy to install and looks nice on the wall. I hope I never have to give a review of its effectiveness in a fire. I will order the hard-wire version in a few years to preplace my other fire alarm. I am very satisfies with this unit.

July 11, 2021so far, so good. Working as expected
Easy to install. No false alarms. Have more confidence in Universal's products than what I have experienced in the past with other brands that fail after a few months. Had positive reviews from customers.

It is too early to give this product a 5 talk to me in 2030. But they seem to be what they advertised. They were easy to install and if they cut out the chirping in the middle of the night for the next 10 years, they will deserve a 10 rating.

I couldn't find a better deal on the internet than this for a 2 in 1 smoke/fire alarm with 10 year battery. I bought 4 and all are working fine.

It took me less than 2 min per unit to install. Impressed with the quality and design. I am also looking forward to not having to find a chirping smoke detector in the middle of the night for the next 10 years!

The alarm came very quickly. It was to replace the alarm in our used travel trailer we recently purchased. I was pleased to discover the unit has a 10 year battery. I didn't know something like that existed.

Was glad to find an alarm that had both the Ionization and Photoelectric technology at a great price. Were easy to install. I recommend this alarm to anyone looking to replace or install a new.

July 28, 2020Easy set up
Once I received all three alarms it only took about two to three minutes per unit to install them on the wall. Very easy. I like the 10 year sealed battery.

Installed new 10-year battery life unit in laundry room without 120V power. Ordered on website, delivery was very quick and installation easy.
The USI MI3050SB 2-in-1 Smoke and Fire 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. Perfect for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes. The sealed battery (included) will never have to be replaced throughout the life of the smoke 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 assist in completely eliminating 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 battery (approximately 10-years from activation).
Perfect for replacing existing USI Electric Alarms, this unit features a large mounting base to cover imperfections in drywall and the option to replace retrofitting applications. The quick activation battery pull tab makes it easy to install while the deactivation key switches the alarm off and makes the batteries safe for disposal. Once the USI Electric Smoke Detector is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.
This USI Smoke Alarm conforms to UL 217 Standards. It has also been approved by the California State Fire Marshal and Federal Housing Authority (FHA) to exceed industry standards. For maximum protection, install an alarm inside every bedroom, outside every sleeping area and on all levels. The USI MI3050SB 2-in-1 Smoke and Fire Smart Alarm comes with a 10-year limited warranty that covers both the battery and alarm.
