Description

The DeNova Detect 10-Year Battery-operated Natural Gas with Voice Alert is America’s first and only 10-year battery-powered natural gas alarm. Designed for fast, reliable detection and equipped with a powerful speaker and LED system, it helps safeguard lives by giving users more time to respond in emergencies. This innovative alarm features MEMS hot-wire semiconductor technology for natural gas detection that is validated to detect explosive levels of gas faster than conventional plug- in alarms. This sensor unit meets strict UL standards for accurate natural gas monitoring. Unlike traditional units, the DeNova Detect DD620NV doesn’t require an outlet or battery replacements. It also eliminates false alarms from everyday household chemicals, making it ideal for families, landlords and utility partners. The alarm speaks directly to the user with voice alerts in both English and Spanish, giving life-saving instructions like “Danger, gas leak explosion risk. Evacuate, then call 9-1-1” during a gas leak. ### In the Box * DD620NV Gas Detector: The main unit, designed to detect natural gas (methane) with voice alerts in English & Spanish. * Battery: A 3V Lithium battery, providing power for the full 10-year life of the alarm. * Mounting Hardware: Includes one screw and one plastic anchor for wall mounting. * User Guide/Safety Info: Important instructions on placement, testing and operation. *This product is not eligible for return.*
