Simple peace-of-mind
I purchased this for my laundry room which sits right below the gas furnace in the attic. It gives me some peace of mind to know that this will detect any CO leaks. Easy to setup and hassle-free due to the 10-year sealed battery. Pro-tip: wear earplugs when testing the alarm. It is LOUD!

Not requiring external power is a big plus. That makes it easy to place it in an optimal location.

Installed this product
The product came in a reasonable time. Easy to install. It hasn't alarmed yet, so that is a good thing, I think.
I have another alarm and it hasn't gone off either, so I believe this new one is working as it should.

Carbon Monoxide Detector
I purchase two MC304SB stand alone carbon monoxide detectors. Installation and testing was easy. Now I need to order 2 more that I shall tie into my security system. Great product, reasonable price, and good installation instructions.

Met all my needs when it was most needed.
We purchased over 115 CO Alarms to meet a new mandate by New York State. The pricing and quality of the alarms, plus the excellent service provided by Universal Security Instruments made this a no-brainer. I highly recommend.
How do I install a battery operated smoke alarm or carbon monoxide detector?
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.
How often should I test my smoke alarm smoke alarm or carbon monoxide detector?
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.
Why should I choose a 10 year battery alarm?
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.
When should I replace my battery operated alarm?
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.
The USI MC304SB Carbon Monoxide Smart Alarm provides 10 years of continuous protection against the silent killer - carbon monoxide. Perfect for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes. The sealed battery (included) will never have to be replaced throughout the life of the co detector, giving you a decade's worth in peace of mind even in the event of a power outage. Permanent Power also saves money from battery replacements (up to $38.00 over the 10-year life of the alarm), eliminates annoying low battery chirps and helps the environment by reducing environmental waste from disposed batteries. This carbon monoxide detector features microprocessor intelligence to assist in completely eliminating nuisance alarms, a single silence/test button to quiet a non-hazardous alarm and an end-of-service life warning that sounds when it's time to replace the battery (approximately 10-years from activation). Mount this carbon monoxide alarm on the wall or leave it standing up on a table top. The quick activation battery pull tab makes it easy to install while the deactivation key switches the alarm off and makes the batteries safe for disposal. Once the co alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.
This carbon monoxide detector conforms to UL2034 Standards. It has also been approved by the California State Fire Marshal and Federal Housing Authority (FHA) to exceed industry standards. For maximum protection, install a carbon monoxide alarm inside every bedroom, outside every sleeping area and on all levels. The USI MC304SB Carbon Monoxide Smart Alarm comes with a 10-year limited warranty that covers the battery and alarm.
