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 in every room. The sealed battery (included) will never have to be replaced throughout the life of the alarm, giving you a decade of 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 completely eliminate 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. This alarm is UL Listed, California State Fire Marshal approved and Federal Housing Authority (FHA) approved to exceed industry standards. For maximum protection, install an alarm inside every bedroom, outside every sleeping area and on all levels of the dwelling.
