Perfect for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes.

The quick 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 exceeds industry standards by meeting new laws and legislation. The Universal Security Instruments MP116S Photoelectric Smoke and Fire Smart Alarm is ETL listed to UL Standard UL 217 and is also California State Fire Marshal approved.

Replace Home Smoke Alarms

While these alarms are pricier than some of the others I elected to purchase them because the lithium battery would mean no changing of batteries, and its not easy to get to some of my detectors and I can get unbalanced fast on a ladder! The Customer Service email contact was EXTREMELY helpful with both tech information and the right alarm to get for the hardwire I already have. I shared with others in my neighborhood this information on our blog!

easy to install, no false alarms so far

This smoke alarm was easy to install, uses the same kind of connector as Kidde alarm it was replacing. No false alarms so far.

Great fit & function

Exactly what i needed. Slim design, great technology, and ease of installation. However, the plastic battery protector pull tab on 1 out of the 5 tore off incorrectly. It's unretreivably stuck inside which caused it to not activate. In process of getting a replacement.
