Eliminates Nuisance Alarms
Abrasive household chemicals, like laundry detergent, disinfectant spray, aerosol hairspray and furniture polish, do not signal false alarms and the aggravation that goes with them.
Micro-Electro Mechanical Systems
Our proprietary sensor, a hot-wire semiconductor sensor with MEMS technology, allows for the alarm's superior responsiveness, reduced size and reduced power consumption.
Long Battery Life
The current DeNova Detect Natural Gas Alarms offer up to 6-years of battery life, with 10-year gas alarm sensors currently in development.
Our natural gas alarms can be installed in a wide variety of environments compared to typical technologies. The battery powered designs allow for installation close to the ceiling where natural gas accumulates, eliminating the need for a potentially dangerous and unattractive cord.
In addition to the 85dB alarm warning sound, our customers appreciate our panic-reducing voice alert that instructs people in this pure and simple way: "Danger - Gas leak explosion risk - evacuate, then call 911."
