USI Carbon Monoxide Smart Alarm With 10-Year Sealed Battery (MC304SB)

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.
