10 Best Gas Leak Alarm In The Us - Black Friday 2024
DeNova Detect Natural Gas Alarm, Only 10 Year 100% Battery-Powered Detector in USA, Alerts 11 Minutes Faster, Voice Alerts in English & Spanish, UL1484 Listed
Main highlights- WARNING! DO NOT test alarm by performing a one-time gas release from a gas stove. This is VERY dangerous and not the intended way to test a natural gas alarm. Natural gas is lighter than air, so it rises to the ceiling first. Simply press the ‘TEST’ button to ensure it’s working properly. We’ve been producing gas alarms for 60+ years without fail, so you can trust DeNova Detect will perform in an emergency.
- Voice alerts in both English and Spanish announce "Danger! Natural Gas Explosion Risk!" and instructions to "Evacuate! Then Call 911"
- Selective to natural gas (methane) and proven to be reisistant to amonia, acetone, ethanol, isopropyl alcohol, and other household chemicals.
- Save money over time. Protection for less than 3 cents a day! No hidden electricity costs or annual battery replacements--ever! Plug-in alarms cost 5X more to own. DeNova Detect saves about $200 per alarm over 10 years.
- Natural gas (methane) alarms should be installed in all rooms where a gas leak may occur, or a gas appliance is located. Easily install in kitchens, laundry rooms, and furnace areas, as well as near natural gas fireplaces.
- Follow proper alarm placement to meet new NFPA 715 installation guidelines. 100% battery powered alarms can be simply installed within 12 inches from the ceiling—eliminates need for the electrical outlet and power cord required with plug-in alarms.
- ETL tested and listed to new UL 1484 safety standards including the low 10% level (LEL) Includes internal self-diagnostics. No calibration needed.
- Battery-powered device enables installation close to ceiling where natural gas is more accurately detected, as natural gas is lighter than air and rises toward the ceiling.
- 100% Battery powered alarm easily mounts on wall, within 12 inches from ceiling and eliminates the need for cords required with plug-in alarms.
- 10% LEL gas alarm threshold alerts you to emergenices much sooner with 11 minutes more escape time on average than a 25% LEL gas alarm threshold.
