Revolutionary sensing technology enables superior features and performance. 10% LEL Natural Gas Alarm threshold alerts you to an emergency situation much sooner than traditional technologies that are designed to alarm at 25% LEL. This Natural Gas Alarm virtually eliminates nuisance alarms caused by harsh household chemicals. This includes: laundry detergent, disinfectant spray, aerosol hairspray, furniture polish and others. Micro-Electro Mechanical System (MEMS) sensor provides accurate and faster detection of Methane gas than traditional type sensors. MEMS sensor technology allows approximately 6 years of battery life, as compared to 1 year of battery life on conventional sensors. This is a battery powered device that enables installation close to the ceiling (where natural gas is more accurately detected, as natural gas is lighter than air and therefore rises towards the ceiling). Battery powered natural gas alarms also remove the need of a cosmetically displeasing cord. The MKRQ-902 Natural Gas Alarm can be installed in a wider variety of environments compared to traditional technologies, including a temperature range of 32°F to 122°F and a humidity range of 5% to 95% RH, non-condensing. 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 explosión por fuga de gas - evacuar, luego llamar al 911".

Where To Install Natural Gas Alarms:
This natural gas alarm should be installed indoors in any room that has a gas-fueled appliance. This can include a stove, furnace, water heater, gas fireplace, or a gas dryer. Natural gas is lighter than air and accumulates towards the ceiling - not by the floor. It should be installed on the wall, between 4 to 12 inches from the ceiling. It should be installed at least 5 feet away from cooking appliances or cooktop hoods and at least 10 feet away from other gas appliances.
Traditional plug-in natural gas alarms are installed too low and may not detect dangerously high-levels of natural gas before reaching an explosive level. Detection can occur earlier when alarms are installed higher in the room, giving residents more time to react appropriately.
LED Indicators On The Alarm:
The Power LED (green) tells you if the natural gas alarm is on. To check if the natural gas alarm is on, hold the Test button for less than 3 seconds, then release. You will hear the natural gas alarm beep once, and the Power LED will blink for 3 seconds.
The Trouble LED (yellow) tells you a few different things with the natural gas alarm. If the Trouble LED is blinking once every 10 seconds, this means the battery is low. If the Trouble LED is blinking twice every 10 seconds, this means the device has reached its end-of-service-life. If the Trouble LED is blinking 3 times every 10 seconds, this means there is a detector error.
The Alarm LED (red) tells you if methane gas has been detected at a concentration above the alarm threshold. In the event of a natural gas alarm, the Alarm LED will blink once every 2 seconds until the gas leak conditions have been resolved.
