Smoke Detector Replacement Advice
The National Fire Protection Association (NFPA) states that the death rate of people in home fires is about 60% lower in homes that have working smoke alarms than in homes with no alarms or no working alarms. Keeping your smoke detector working is more than changing the battery. You also need to replace it.
Whether your smoke detector has a replaceable battery, a sealed battery meant to last 10 years, or is hard-wired into your electrical system, it’s essential to know when to replace it. Most of the time, you can find the replacement date on a sticker that is on the smoke detector itself. If you can’t find the sticker, then the general rule is to replace it once every 10 years.
You should also replace the smoke detector if it isn’t working. You can test it by pushing the test button. It should make a loud noise. If the alarm does not make a noise when you test it, then it’s time to replace it.
If your smoke detector requires a battery, it will start beeping or chirping when the battery needs to be replaced. Sometimes, the detector may continue to beep or chirp after you change the battery. This is another sign that you need to replace the detector.
Hopefully, your home will never have a fire in it, but if it does, it’s important to replace all the smoke detectors in your home after a fire incident.
Rules for Replacing a Carbon Monoxide Detector
According to the CDC, more than 400 Americans die from carbon monoxide (CO) poisoning every year. More than 100,000 people in America visit an emergency department due to illness from CO poisoning. Having a carbon monoxide detector in your home can save your life, so it is incredibly important to make sure it’s running properly.
Most carbon monoxide detectors can safely operate for 5 to 7 years. After that, it’s time to replace them. If you are not sure how old the CO detector is, then you should err on the safe side and replace it.
Carbon monoxide detectors typically have an end-of-life signal. The alarm may sound every 30 seconds, or the digital display may read END or ERR on it. If you change the detector’s battery and the beeping persists, it likely means that the detector has reached the end of its life and needs a replacement.
