Customer Reviews For The DeNova Detect Battery-Powered Propane Gas Alarm

Innovative 5-Year Battery Life and Safety

The DeNova Detect DD720PV provides the first and only 5-year battery-powered propane gas alarm in the U.S. Powered by an included 3V lithium battery, it delivers 5 full years of maintenance-free peace of mind with no replacement batteries or electricity required. Because it does not require an outlet, you get flexible placement options to ensure continuous protection even during power outages.

Advanced MEMS Sensor Technology for Faster Warnings

This innovative alarm features advanced MEMS hot-wire semiconductor technology for propane gas detection that is validated to detect explosive levels of gas faster than conventional plug-in alarms. Calibrated to an ultra-sensitive 10% LEL (Lower Explosive Limit) threshold, it responds faster than alarms with 25% LEL thresholds, offering up to 11 minutes more escape time. The advanced MEMS sensor provides higher sensitivity while remaining virtually immune to nuisance alarms caused by common household chemicals like hairspray or cleaners.

Code-Compliant Placement and Dual Warnings

Designed to meet NFPA 715 recommendations for propane gas alarms, the DD720PV mounts easily to any wall using the included screw. Propane is heavier than air and sinks to ground level, so the unit installs completely within 18 inches from the floor in an area free from obstructions. Equipped with an 85 dB alarm volume at 10 feet and bilingual voice notifications in English and Spanish, it ensures critical warnings are heard clearly across residential spaces and rental properties.

Intelligent Self-Diagnostics & Visual LED Alerts

Internal systems continuously run automated checks to ensure dependable operation throughout the device's five-year lifespan. Clear visual LEDs and spoken alerts notify you immediately if the unit detects a system fault, a low battery, or reaches the end of its service life.
