Customer Reviews For The USI Hardwired 2-in-1 Universal Smoke Sensing Smoke and Fire Smart Alarm

Replacement units

Easy to replace my 10 year old units. I called in and someone helped me to ensure that I purchased the correct units. Thank you!

replacement

Ordered 4 smoke detectors w/10 year battery. Process was simple delivery was quick and installation went without an issue. My second time dealing with Universal and I will continue to purchase from them.

Just what I needed

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.

prompt service easy to install

Came on time as states, and easy to install.

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.

Easy install. Now no worries about changing batteries 2x/yr

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.

As expected

Replaces obsolete USI detectors with no problem

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.

2 & 1 smoke alarms

I have 6 of thsesin my house have had good service from them all

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.

Re-placements

I ordered replacements for my home and they were on time and working properly.

Easy replacement

I ordered direct from USI electric. The six pack was packaged neatly and securely. This detector replaced our 12 year old USI product and plugged into the existing harness. It was necessary to change the base plate, which was quick and easy. The 10 year sealed unit is a real plus. All in all, a great product.
