The Universal Security Instruments 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 alarm, 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 alarm 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 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 alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.

This alarm 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 an alarm inside every bedroom, outside every sleeping area and on all levels. The Universal Security Instruments MC304SB Carbon Monoxide Smart Alarm comes with a 10-year limited warranty that covers the battery and alarm.

Good product.

Easy to set up and works immediately. I'll probably purchase more of these for the rest of my house.

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!

Monoxide Alarm

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.

USI Carbon Monoxide Alarm

Arrived promptly. Was looking for an alarm to use in new room. Easy to mount on wall. This unit should last 10 years.
