    Q:Please explain the relationship and differences of NFPA 72, NFPA 501C, UL 2035, and UL 217 and where they differentiate between gases/vapors vs smoke?
    by|Sep 28, 2023
    1 Answer
    Answer This Question

    A:  Hello. Our residential alarms meets the national fire codes of NFPA 72. Our smoke alarms are UL 217 listed and the our carbon monoxide alarms are UL 2034 listed. The National Fire Protection Agency code 72 is the code used as the template for most state and local fire codes and the United Laboratory standards are the standards that our alarms are made to and our alarms are certified and listed with UL for these standards. Alarms that meet these UL standards are usually required in most state and local codes. We are not sure what NFPA 501C or UL 2035 is. Please feel free to reach out to the NFPA and UL for more information about these fire codes and standards. Contact your local authority requiring smoke alarms and carbon monoxide alarms as to what your local and state codes require.

          safe home
          Kidde Firex Carbon Monoxide Detector replacement. The old one was just that, old. It started chirping one day and I pressed the "Hush" button. I replaced the batteries with new ones, but a few days later, it started chirping again. I went to the Kidde website for more information. The detectors do have an expiration and mine had reached it's life limit. I had not dated the old unit but feel sure it was over the ten years it was built to last. I marked the new unit before I installed it and each year when I replace the batteries, now I will know when to replace the unit. The unit comes with batteries, installation instructions, and mounting screws and spacers. Good value for home safety.

          Appears to be a great value. I can't say how good it works yet because you can't smell or see carbon monoxide. If I'm still alive in 10 years it's either because it worked or I haven't had a carbon monoxide leak in my house. I did buy 2 of them because I wanted something to protect my family and I don't have a lot of money. I also bought 6 smoke detectors because out of every place I checked Home Depot had the best price easily. I think that they might be doing this on purpose to help keep people safe. Thank you Home Depot.

          Unit works as required by city ordinance but the batteries outlasted the CO sensor inside. The projected life is 7 years but all of mine failed in about 6 years. The new ones are good for 10 years. Wonder why the manufacturer doesn't supply a plug-in CO sensor instead of making you throw the entire unit out, Could be expensive and labor intensive if you have many apts.

          Response from Kidde ExpertJun 4, 2019
          Hello. The price of the sensor is a large portion of the cost of the alarm itself. Making the sensor reliably replaceable would increase the cost of the alarm and the replaceable sensor might cost almost as much as a new alarm.

          We purchased two of these detectors. We have a new house that has interconnected smoke detectors, but when I read about them it did not say they detected carbon monoxide. We have an attached garage, a gas fireplace and a gas furnace. Carbon monoxide could come from any of these. We would rather be safe than sorry. This detector is relatively inexpensive and easy to install. I would recommend it to anyone.

          Easy to install. My previous Kidde CO alarm expired exactly 7 years to the manufacturing date. It's nice that the newer version comes with batteries and less for 10 years now.
