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.

Arrived promptly and was easy to install. Should do me for 10 years but it was nice that you did what you said you would do.

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.

works good

Hi, had to replace my detectors since they were starting to go off when I cooked. They were 10 years old. I ordered 2 iono detectors 3 photo detectors and 1 carbon monoxide one all 10 year sealed and wired ones. They all installed and worked good and solved my cooking problem. Also the customer service was very responsive and the items were shipped quickly A+. Kevin

The Universal Security Instruments MP116S Photoelectric Smoke and Fire Smart Alarm provides 10 years of continuous protection against deadly threats in the home. The utilization of Photoelectric Technology allows for increased efficiency in detecting 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 detector features smart alarm technology 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).

The perfect replacement for 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 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.
