Q: How many Natural Gas Alarms should I have in my home?
A: DeNova Detect recommends installing a Gas Alarm in every room where you have a natural gas appliance—such as a stove, furnace, dryer, water heater, or fireplace.

Q: What is the battery life of the DeNova Detect 10-Year Wireless Natural Gas Alarm?
A: The battery lasts for the life of the product, which is approximately 10
years. If a replacement battery is needed within the 10-year lifetime, you can
contact DeNova Detect. The battery used for the alarms is not available at
retail stores.

Q: Will my carbon monoxide alarm detect natural gas leaks?
A: No. Carbon monoxide alarms are not designed to detect natural gas. You need a dedicated Natural Gas Alarm like DeNova Detect DD620NC or DD623NCV for that purpose.

Q: Is pressing the test button the only way to test my alarm?
A: Yes. You should always test your alarm using the designated test button. Do not use actual gas to test the alarm. Refer to the owner’s manual for additional information.

Q: How do I know my alarm is working?
A: Regular testing with the test button and visible indicators (LEDs) help ensure it is functioning. The green LED remains off during normal operation. Refer to the owner’s manual for additional information.

Q: How often should I replace the battery?
A: The battery does not need to be replaced; the entire unit should be replaced after the life of the product. If a replacement battery is needed within the product’s lifetime, you can contact DeNova Detect. The battery used for the alarms is not available at retail locations. Refer to the owner’s manual for additional information.

Q: When is it time to replace my Gas Alarm?
A: Replace the alarm when it reaches the end of its service life or if the “Trouble LED” is active and cannot be resolved. Refer to the owner’s manual for additional information.

Q: Why does my Gas Alarm chirp approximately once every minute?
A: This indicates that the battery is low. You will also see the “Trouble LED” on the device blinking once every 10 seconds, and the audible alert will beep once and say “Low Battery” every minute. Refer to the owner’s manual for additional information.

Q: What do I do if my alarm goes off?
A: Evacuate the building immediately. Do not operate lights, electronics, or phones. Once you’re safely outside, call 911 or your local gas utility to report the leak.

Q: What is the size of the alarm?
A: The DD620NV/DD623NCV measures 3.8 x 3.8 x 1.6 inches and the ML-310ES measures 3.3 x 3.9 x 1.3 inches.

Q: What is the difference between a carbon monoxide and Natural Gas Alarm?
A: CO alarms detect carbon monoxide—a byproduct of incomplete combustion. Natural Gas Alarms detect methane leaks from fuel lines or appliances.

Q: Can something else trigger my alarm to go off?
A: It is unlikely household objects such as aerosols or cleaning agents will cause nuisance alarms to DeNova Detect alarms; however, when cleaning the alarm do not use spray cleaning chemicals or insect sprays directly on or near the Gas Alarm.

Q: Why is my alarm going off if there is no gas leak?
A: The alarm can beep for several indications; please refer to the user manual
for details. If the alarm for a gas leak is activated and it is confirmed there is no gas leak, the alarm may be faulty.  

Q: Why do I need a Natural Gas Alarm if I can smell gas?
A: Some people may not recognize the smell, especially if they have a reduced sense of smell or are sleeping. The alarm provides critical protection.

A: LEL refers to the lowest concentration of gas in air that can ignite. DeNova Detect alarms activate at 10% LEL to provide early warning.

Q: What does the “Power LED” do?
A: The “Power LED” indicates the device is powered and functioning properly. To check if the Natural Gas Alarm is on, press the Test button. The “Power LED” remains off during normal operation. Refer to the owner’s manual for additional information.

Q: What does the “Trouble LED” do?
A: The “Trouble LED” alerts you to a malfunction or issue, such as low battery
or device fault, or that the alarm has reached end-of-service life. Refer to the owner’s manual for additional information.

Q: What does the “Alarm LED” do?
