The USI AMIB3051SC 2-in-1 Sensing Plus® Smoke and Fire Alarm provides 10 years of continuous protection against deadly threats in the home. New Sensing Plus® Multi-Criteria Detection provides the benefits of both photoelectric and ionization detectors 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.

10 Year 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 smoke and fire detector features microprocessor intelligence that assists 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 smoke detector's battery (approximately 10-years from activation).

Perfect for replacing existing Universal Security Instruments Alarms, this smoke and fire detector 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 10 year smoke and fire alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.

This 10 year smoke and fire alarm conforms to UL 217 Standard 8th Edition. 8th edition smoke and fire detectors have also been approved by the California State Fire Marshal and Federal Housing Authority (FHA) to exceed industry standards. New Sensing Plus® Multi-Criteria Detection provides:

  • Resistance to False Alarms from Cooking.
  • Detection of Polyurethane Foam in both Slow Smoldering & Fast Flaming Fires.
  • Immunity to High-Voltage Current Surges.

For maximum protection, install a smoke and fire detector inside every bedroom, outside every sleeping area and on all levels. The USI Electric AMIB3051SC 2-in-1 Sensing Plus® Smoke and Fire Detector comes with a 10-year limited warranty that covers both the battery and alarm.

Meets New Laws & Legislations - This alarm exceeds industry standards, and is listed to UL Standard UL 217 8th Edition and is California State Fire Marshal approved.

*New Security Sensing Plus® Detection Technology UL 217 8th Edition Tests Include:

  • Resistance to false alarms from cooking
  • Detection of polyurethane foam in both slow smoldering & fast flaming fires
  • Immunity to high-voltage current surges

How often should I replace the battery in my smoke, CO and natural gas alarms?
Many of our alarms come with a 10-year sealed Permanent Power battery that never needs replacing during the 10 year life of the alarm. Batteries in non sealed alarms should be replaced at least once a year or when the low battery signal sounds. Permanent Power battery technology helps keep you safe, because working smoke alarms are an important factor in surviving a home fire.
What's the optimum placement of protection devices in my home?
Early detection of smoke, carbon monoxide, and natural gas is key to saving lives. The National Fire Protection Association (NFPA) recommends installing a smoke alarm on every level of your home, including finished attics and basements. You are also encouraged to install a smoke detector inside every bedroom and at the top of certain stairways.
Do I need four kinds of detectors or can one do it all?
You never know what kind of hazard will strike your home, or when. That's why we recommend technology that can detect carbon monoxide (CO) and natural gas as well as smoke and fire. You'll get the most protection from devices that can quickly and accurately detect and respond to a range of threats.
What are "nuisance alarms"? Why are they a concern?
A smoke alarm that goes off when there's no emergency is annoying. According to the National Fire Protection Association (NFPA), such "nuisance alarms" are the leading reason why homeowners intentionally disable their smoke detectors. Yet doing so can be deadly. A survey conducted by the NFPA found that smoke alarms sounded in only half of the home fires reported to U.S. fire departments, and almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms.

Just what I was looking for

I couldn't find a combination smoke and flame alarm at the hardware stores near me, so this bedroom specific alarm was a perfect find. Previously we only had an alarm in the hallway, so now having alarms in all three bedrooms has given me major peace of mind, in case a fire originated in the bedroom and the door was closed. They were easy to install as well.

Future-proof fire safety for our bedrooms

We had a minor scare when a defective CFL bulb in our bedroom failed and began to smoke, setting off our bedroom smoke alarm. We had not yet installed smoke alarms in our other bedrooms, plus our alarm was nearing its end of life, so I took this opportunity to research smoke alarms and see what was available. It turns out that UL is updating their smoke alarm standards UL217 to an 8th edition. This will require better sensing technology to reduce nuisance alarms as well as to better detect polyurethane foam fires. Only a few alarms sold today meet this standard, this one from USI being one of them. Having a 10 year battery in it is also a big plus, doing away with yearly battery changes. These were easy to install I made sure to keep at least three feet away from the ceiling fan blades. Now our bedrooms are protected for the next 10 years.

As advertised

Received 10 detectors, all were easy to install and worked well under test. Hopefully, we don't have to find out how they work with a home fire.

USI Sensing Plus AMIB3051SC Bedroom Smoke & Fire Alarm With 10 Year Battery

Fast delivery and easy to install. I replaced my 14 year old hard wired alarms and was able to use the same mounting bracket. I will let you know in 1-0 years if the batteries last that long---

Process for ordering was very smooth. I had a question about the alarms and response on phone was excellent. I would definitely order from Universal again.
