Overall Rating
Product Reviews
I bought most of my CO monitors from this company. Absolutely reliable
I love this company's products. I've changed all my alarms to universal security products mainly as they are very reliable and easy to install.
First time using Universal, the price was competitive, the order process and delivery was quick.
Great service Will not hesitate to purchase from]them again
Worth every dollar for it . East install, last around 20 Years . Love the desolate and works well. Had them tested yearly . Our second go around with them.
Thank you for this product! Once I found this, it is the only one our Fire Department gives out! It has all the elements that are needed for a competent customer use: digital, 10 year sealed battery, disarm key, not a plug in, versatile to be hung at eye-level. All these features are important to fight this world-wide battle against CO poisoning. Only negative? I wish it was advertised and easier to purchase. Thank you for all you do.
Previously we've used other brands of plug-in CO detectors found at the big box stores -- useless during an electric outage and they failed before the warranty ended. We searched and found USI products. These USI CO Smart Alarms are well made and great value. Love they have a 10 year sealed battery, and can be used tabletop or easily wall mounted. Just added two more to our home. So easy to order, and fast shipping from USI. These last, are well made and give us peace of mind - thank you!!
The CO alarms came quickly and were easy to install.
as expected thank you
No false alarms, has a helpful digital display. Easy to test.
Have used Universal Security CO monitors for years. Decided to try 10 year battery monitor instead of changing batteries every year - after using their 10 year smoke detectors for the past 2 years. Great products..
Delivered promptly. Quick and easy to setup. Best part is smart alarm with 10 year sealed battery.
So far, so good
Small unit that is easy to install.
This CO2 detector is perfect. I don't have to replace the batteries. I had some questions as to where to place the detector and phone support was very helpful.
Excellent value -- I did lots of research -- quick, accurate delivery
I was glad to get a product that didn't have the battery replacement issue, a ten year battery is great. I wish the smoke alarm had this kind of battery available.
So far I haven't needed to use it yet. When I reinstalled the battery in the older system it seems to work. No more one beep. I am keeping them until needed.
This product was easy to set up. We set them on table tops. We tested them after I pulled the tab to activate them. They are small and very loud. We are very happy with them and would buy them again!
Product FAQs
Installation is a simple DIY project. Most models come with a mounting bracket and screws. After marking the location on the wall or ceiling, you can simply screw the bracket in place and then twist the alarm onto the bracket. For more information and installation instructions, please follow the instructions that were included with your specific model.
You should test all of your smoke alarms and carbon monoxide detectors at least once a month. This is as simple as pressing and holding the "test" button on the unit until it sounds. This ensures the alarm's sounder is working properly.
A 10-year sealed battery alarm offers a decade of continuous protection without the need for battery replacements. This eliminates the risk of an alarm failing due to a dead or missing battery, saves you from the hassle of annual battery changes, and prevents the annoying low-battery chirps that often happen in the middle of the night. It's a "set it and forget it" solution for a full decade.
Fire safety experts, including the NFPA, recommend replacing smoke alarms every 10 years. This is because the internal sensors can become less sensitive over time due to dust, dirt, and age. For alarms with a 10-year sealed battery, the replacement is straightforward, as the alarm will sound an end-of-life warning when it's time to be replaced.
