DeNova Detect DD720PV: 5-Year Battery Propane Alarm & Gas Detector with Voice Alerts

Safeguard your home with the DeNova Detect DD720PV, America’s first 5-year battery-powered propane alarm. This completely wireless propane detector triggers up to 11 minutes faster than traditional gas detectors, giving your family rapid, life-saving warnings the moment liquid petroleum (LP) gas leaks begin.

DeNova Detect DD720PV 5-Year Battery Propane Alarm and Propane Gas Detector

Next-Generation Propane Detection: Up to 11 Minutes Faster

Standard plug-in gas alarms rely on older sensor types that need significant gas buildup before triggering. The DeNova Detect DD720PV propane alarm changes that standard with micro-electromechanical systems (MEMS) sensor technology. Engineered to sound an alarm at just 10% Lower Explosive Limit (LEL), this high-precision propane detector warns you long before combustible gas reaches hazardous concentrations. That early response delivers up to 11 additional minutes of critical evacuation time.

Cordless Battery Freedom with Clear Spoken Voice Warnings

Unlike AC plug-in units that tie protection to floor-level power outlets, the DD720PV propane gas alarm runs on an included 5-year lithium battery pack. This standalone battery design ensures non-stop gas leak protection during severe weather, grid outages, and electrical emergencies. When the sensor identifies a leak, it pairs a loud 85 dB audible siren with a direct spoken voice message: “Danger. Gas leak explosion risk. Evacuate, then call 911.” This direct instruction cuts through panic and directs everyone to safety without hesitation.

Propane Alarm Placement Tip

Propane gas is heavier than air, meaning it sinks and pools along the floor during a leak. In accordance with NFPA 715 safety standards, mount your propane alarms low on the wall within 18 inches of the floor near gas appliances such as ranges, water heaters, and furnaces.

Core Performance Features

5-Year Battery Operation

Runs continuously on an included 5-year power pack, eliminating messy power cords and keeping protection active during blackouts.

Fast 10% LEL Early Detection

Triggers at just 10% LEL to alert residents up to 11 minutes sooner than conventional propane detectors.

Clear Voice Evacuation Prompts

Delivers explicit spoken instructions alongside an 85 dB horn so everyone in the home knows how to respond immediately.

Nuisance Alarm Resistance

Advanced MEMS sensor technology ignores household aerosols, cleaning sprays, and cooking vapors to avoid false alarms.

NFPA 715 Safety Compliance

Engineered to satisfy modern fuel gas detection guidelines across residential properties, rental units, and vacation cabins.

Simple Low-Wall Mounting

Installs quickly using standard mounting screws without hardwiring, placing the detector right where heavy propane collects.

Where to Install Your Propane Gas Alarm

Because liquefied petroleum gas settles downward, correct sensor height is vital for early leak detection. Install your DeNova Detect DD720PV propane alarm on an interior wall between 4 and 18 inches above the floor, and keep it within 3 to 10 feet of propane appliances such as stoves, dryers, space heaters, and boilers. For unobstructed air circulation, avoid positioning detectors behind closed doors, behind drapes, or inside unventilated utility closets.
