This was my second purchase from Universal Security Instruments, Inc. The items were received quickly and were in perfect condition. Their pricing was the best I found. I'm currently working on my third order. Great job. Thanks,

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.

Perfect for Multi-family

These are the perfect alarm for multi-family units. Tamper proof 10 year batteries and tamper proof mounting. Just set them and forget them, until they tell you it's time to change the alarm 10 years later.

So far so good

Upgraded original home alarms with three of these dual sensor units with 10 year battery backup. 2 units activated with no issues. The third unit failed to beep after pulling the activation tab. And continued to beep once every minute or so. I unplugged the device, pushed the test button again, and it chirped properly. I reinstalled and tested all 3 with no further issues.

Replace 10yr old smoke alarms

The product performed perfectly. Installation only required a quick change of the base mount. The wiring was compatible with the previous model. The 10yr battery was the selling point.

Exactly what I needed

I went to Lowes, Home Depot, and Walmart looking for a fire alarm that I could replace with my old one. None of the 4 I bought had the correct adaptor. The first one I got from USI was perfect. Will be replacing another very soon

Easy to install, no false alarms

I ordered this to replace an older wired smoke detector. I turned off the electricity, removed the wiring harness from the old detector by twisting off the wire nuts and installed the harness from the new detectors. There were no false alarms since I installed it.

I ordered 3 of the USI 2-in-1 hardwired smoke and fire alarms online so that I could replace my current smoke alarms that have expired. They arrived on the date they were supposed to and were easy to install and test. I am looking forward to not having to replace any batteries for 10 years. I highly recommend.

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.
