Universal Security Instruments - The MCND401 Plug-In Carbon Monoxide and Natural Gas Smart Alarm is a 2-in-1 device that provides double the protection with a single installation. This dual-sensing alarm protects against two deadly household threats: carbon monoxide and natural gas (or methane). Perfect for new or replacement installations, the 120-volt AC alarm is suitable for houses, apartments and mobile homes. The compact plug-in design covers only one outlet for a fast and easy installation with no wiring required. This alarm features microprocessor intelligence to 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 7 years from activation). The digital display screen provides carbon monoxide PPM (parts per million) levels and displays "GAS" during an occurrence. Peak CO levels are recorded with the memory button and three LED colors display the status of the alarm, power, CO and gas in the home.
9-volt alkaline battery (included) continues protection in the event of a power outage
