The Universal Security Instruments 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 alarm, 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 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 Universal Security Instruments 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 alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.

This 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 Universal Security Instruments MI3050SB 2-in-1 Smoke and Fire Smart Alarm comes with a 10-year limited warranty that covers both the battery and alarm.

Smoke Detector

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.

I 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.

2-in-1 Detector

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,

An 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? πŸ‘πŸ‘πŸ‘

So 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.

Pleasantly 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.

so 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.
