- Bilingual Spoken Voice Alerts: 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.
- Certified Code & Standard Compliance: Conforms to UL STD 1484, features a propane sensor listed to UL STD 2075, and complies with NFPA 715 installation recommendations.
DeNova Detect Battery-Powered Propane Gas Alarm Product Description
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.
Why Choose a DeNova Detect Propane Gas Alarm?
Focused Propane Protection
Designed specifically to detect propane gas, unlike multi-gas sensors that may not be optimized for propane detection.
Earlier Propane Gas Detection
Advanced MEMS hot-wire semiconductor sensing technology detects propane at 10% of the Lower Explosive Limit (LEL), providing earlier warning than conventional alarms that activate at 25% LEL.
5-Year Battery Protection
Long-life battery-powered operation provides continuous protection without requiring an electrical outlet or hardwiring.
Clear Voice Alerts
English and Spanish voice alerts provide clear evacuation instructions during a propane gas emergency.
Easy Installation
Battery-powered design requires no wiring or electrical outlet. Easily mounts to a wall using a single screw.
Engineered for Reliability
Advanced sensing technology is designed to minimize nuisance alarms caused by common household chemicals.
Install Your Propane Gas Alarm Where It Matters Most
Because propane gas is heavier than air, it can collect near the floor when a leak occurs. The DeNova Detect DD720PV Battery-Powered Propane Gas Alarm is designed to mount on the wall within 18 inches of the floor, helping detect propane where it may accumulate.
Unlike traditional plug-in propane detectors, the DD720PV requires no electrical outlet, power cord or hardwiring. Its cordless design allows for convenient placement at the manufacturer's recommended height and distance from propane appliances, without relying on the location of existing outlets. With a 5-year battery-powered design, 10% LEL detection and bilingual voice alerts, the DD720PV offers a practical solution for residential propane gas safety.
