The Universal Security Instruments MIB3050S 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 smoke and fire 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 2-in-1 smart alarm includes 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. This makes the batteries safe for disposal. Once the smoke and fire alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.

This USI Smart Alarm conforms to UL 217 Standards. This 2-in-1 smoke and fire alarm 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 MI3050S 2-in-1 Smoke and Fire Smart Alarm comes with a 10-year limited warranty that covers both the battery and alarm.

Lots of alarms

I placed the alarms in 7 places after I did the first one the rest were easy. They were easy to twist on and off the base 10 years of no battery replacement is a nice feeling.

Best way to go

These smoke alarms were easy to install and look good. It's good to know that we won't have change the batteries every year and hear the beeps when they need it. Delivery was very fast.

Protect

I purchased 55 new smoke alarms to replace my 10 yr. old smoke alarms. I had hard wired smoke alarms but decided to go with the 10 yr. Battery alarms. They were very easy to replace and quickly done. I liked the fact that the plate was a little larger to cover any blemish on the ceiling. Now we feel very secure for the next 10 yrs.

could use an installation template

This product is exactly what I wanted. I replaced all the old smoke detectors I had with it. My only issue is that the mounting bracket could use an installation template so the holes for a slide on installation would be more obvious.

Easy install / excellent appearance

Oversize base-plate is excellent. No problem covering all signs of old installation. Easy to temporarily remove when time to paint the ceiling.
