The USI MI106S Smoke Alarm features a 10-year sealed battery for permanent power and continuous protection in the event of a power outage. Universal Smoke Sensing Technology detects fast flaming fires and slow smoldering fires while microprocessor intelligence virtually eliminates nuisance alarms for the perfect two-in-one home safety protection. Studies show that one of the leading causes of preventable death due to smoke and fire is a deactivated or inoperable alarm. This USI Hardwired Smoke and Fire Alarm is equipped with a 10-year sealed battery that provides a decade in peace of mind, while removing the need for battery replacement. Permanent Power allows you to simply install and activate the alarm for protection that will last for up to 10 years. This gives you maintenance-free battery power, eliminating low battery chirps and the need to buy replacement batteries throughout the life of the alarm. Purchasing a permanent power alarm saves you money and reduces environmental impact by providing environment friendly protection. This USI Smoke Detector reduces environmental waste and eliminates disposal of up to twenty 9-volt batteries.

Easy installation, no false alarms

I installed two of these as replacements. The installation was simple and we haven't had any false alarms.

Great product. Change every 9-10 years instead of changing batteries every 6 months. Easy to change out old inefficient alarms. Once installed, future replacements take 1-2 minutes to install

Excellent Customer Service

When I called to replace my 18 year old hard wired alarms, the agent was extremely helpful regarding both my options and how to do the install myself. Referred me to a Youtube video... shipment came right away at a price lower than I expected.

Hardwired Smoke Alarm

Item was purchased as a replacement for an expired unit. Unit installed exactly like the one replaced and is working as discribed. I especially like the 10 year sealed battery.

Easy replacing connected devices

In less than 1 hour I took down 8 old USI devices and replaced them with new ones. Love the 10 year sealed battery, no more semi annual 9v battery replacement.
