Impressed with simplicity

I must say, I am thoroughly impressed with the Denova ML-330 Natural Gas Alarm. As an elder who values safety above all else, this device brings me great peace of mind. The installation was simple, and the compact design fits perfectly in my home. The loud siren, voice alarm and bright LED display ensure that I am immediately alerted to any gas leaks, I recommend this gas alarm to fellow seniors who prioritize safety and want an easy-to-use solution to protect their homes.

Units arrived in a day from order and were very easy to setup and install. I have one in our furnace room and one by my gas fireplace just in case. Wish they were less expensive however the customer service rep gave me a coupon code to get them discounted a little bit. Thanks again for answering all my questions.

DeNova Detect Natural Gas Alarms by New Cosmos USA offer protection against the threats of natural gas (or methane) hazards. This natural gas alarm is suitable for houses, apartments and manufactured housing. DeNova Detect Natural Gas Alarms are manufactured to a 10% LEL gas alarm threshold, alerting you to an emergency much sooner than traditional technologies that are designed to alarm at 25% LEL. This alarm features superior technology that virtually eliminates all nuisance alarms. In addition to an 85dB alarm warning sound, this Natural Gas Alarm includes the following voice alerts in English and Spanish: "Danger - gas leak explosion risk - evacuate, then call 911". "Peligro - riesgo de explosion por fuga de gas - evacuar, luego llamar al 911".

The contemporary design is fast and easy to install. No wiring is needed to install this natural gas alarm. DeNova Detect Natural Gas Alarms are ETL tested and listed to UL1484 Standards. It is advisable to install natural gas alarms in all rooms where a gas leak may occur, or a gas appliance is located. Examples include kitchens, laundry rooms, and furnace areas. The DeNova Detect ML-310ES Natural Gas Alarm comes with a 7-year limited warranty.

Easy to install - mounts with one screw, no wiring or bracket necessary:

The DeNova Detect Natural Gas Alarm should be installed in all rooms where a gas leak may occur or a gas appliance is located. Examples are a kitchen (gas leaks from gas ovens and cook tops), laundry (gas leaks from a gas clothes dryer), and furnace area (gas leaks from furnace burners or boilers). However, do not install closer than 10 feet (3 meters) from gas appliance. It is possible that gas leaks may migrate along pipes so consideration should be given to place gas alarms in multiple rooms. Gas alarms should be located between 6 to 12 inches (0.15 to 0.3 meters) from the ceiling.
