USI Electric Carbon Monoxide and Natural Gas

This alarm replaced my previous hard-wired USI Carbon Monoxide alarm. It was reasonably priced and delivered to my home on time. It was very easy to install as the electrical connector was the same as my previous model. It also detects Natural Gas as an added bonus. Overall, I am very pleased with this purchase and would recommend it.

USI Product and Service

Typical quality product from USI, with a good selection of options and ease of installation. I continue to purchase from Universal because of their excellent customer service, very prompt order fulfillment and shipping.

Outstanding alarm

So I was trying to exactly match the CO2/gas alarm we had and this one was the exact match. The alarm arrived promptly and works great!

MCN108 2-in-1 CO2 & Natural Gas Alarm

I have used the USI 2-in-1 CO2 and Natural Gas models for over 15 years. The product works well, however it doesn't always live a 7 yr life

Love them. They work really good.

Easy Installation

The alarms in the house I purchased at the end 2018 had these alarms, and I noticed they were already three years out of date, and were still working. I decided to replace them with these from the same company, as they seem to be pretty reliable.

Replacing existing detector was a snap

This new detector was replacing an existing one, which was at its end of life. The installation was very easy and quick. I will definitely be purchasing any detectors I need from USI in the future.
