How To Know When It’s Time To Retire Your Smoke Detector

How often should you change the batteries in a smoke detector?

Some smoke detectors will simply need to be replaced, especially after their expiration date of 10 years.

No matter how well an appliance or tech gadget is working, it’ll have an expiration date. The same goes for smoke detectors, which the NFPA recommends replacing after 10 years regardless of their condition.

Along with this information, you can check your alarm’s expiration date, which makes it easier to know exactly when it’s been 10 years. You can find this by removing the smoke detector from the wall or ceiling and looking for the date on the back.

Why Does Your Alarm Go Off In The Middle Of The Night

If your alarm only chirps at night while youre cozy in bed, you may be tempted to believe its messing with you deliberately. However, there is actually a technical explanation for this behavior. The phenomenon is a result of two factors:

  • The batteries in your device are running low.
  • The temperature in your home falls at night. Lower temperatures cause power to drain more quickly from batteries.9

In short, your low batteries dont chirp during the day because they are putting out just enough power. However, if they are weakening at night, they begin to run low and you should replace them.

How Often Should You Replace Smoke Detectors How Long Do They Last

Smoke detectors play a crucial role in keeping a home and all its occupants safe. A good smoke detector can last for quite a while, helping to detect smoke and sound the alarm. However, over time, such a unit gets worn out and needs a replacement.

It is recommended that you change a smoke detector after 10 years. However, you should also do checkups to see if theres any need for early replacement or not. Wear and tear coupled with dust and electrical corrosion lead to smoke detectors breaking down and needing earlier replacement.

Read on to learn why its essential to change smoke detectors and when to change the batteries and perform checkups for these units.

Know What Type Of Batteries To Use

A good way to figure out how often to change the batteries is to know what type your detectors use. Some use lithium batteries that can last up to ten years, but these typically expire when the batteries do. Others use options that wont last near as long, but dont need to be replaced often. You will need to become familiar with the batteries your devices use and where to get them.

What Does It Mean When A Smoke Detector Blinks Red

Smoke alarms will make a beep or chirping sound when they have a low battery or are faulty. All smoke Alarms also have a red light that flashes momentarily every 40-60 seconds to visually indicate they are operating. This same red light flashes continuously when the Smoke Alarm has been activated.

What If Your Problem Is False Alarms

Chirps can be annoying, but false alarms can be a real problem. When your smoke alarm goes off and theres no fire, you can become complacent, assuming every time theres an alarm that it isnt an actual emergency. Then, when an emergency does happen, you arent prepared.

What can you do, though, to eliminate false alarms? As it turns out, many of the same problems that lead to chirping can also cause false alarms. This means that many of the same fixes will work for false alarms. These are our suggestions:

  • Check your batteries.
  • Make sure your detector is clean and free of dust.
  • If you have experienced a power outage, reset your alarm.
  • If your unit is 10 years old or more, replace it.
  • These factors can also cause false alarms:

    Current Fire Protection: How Long Do Smoke Detectors Last

    Take a hard look at the fire alarm in your house. How long have you had it? If your answer is more than 10 years then its probably time to replace it.

    After they hit the 8-year mark you should consider replacing it. A 9-volt battery detector can live up to 10 years if you take care of it.

    2. Long-Life Battery

    Long-life battery smoke detectors use lithium batteries to power them. These types of alarms work a little differently than others because you have to go by how long the battery will last. Not how long the unit will.

    This is because you can’t change the lithium battery. When your alarm hits the 10-year mark you will have to replace the entire unit.

    3. Hardwired

    Hardwired alarms appear to be permanent fixtures in your home but you have to follow the same rules for it as you do other types of alarms. Like with the 9-volt battery models, you will need to change the battery once every year.

    4. Test Regularly

    How Will I Know If My Smoke Alarm Needs A New Battery

    Most smoke alarms will emit a small chirp/beep once every 30 to 60 seconds, and as annoying as it is, please dont ignore it as this indicates the battery needs replacement.

    These low battery warning chirps will be quick, high pitched chirps heard continually every 30-60 seconds.

    As a general rule of thumb, even for the best smoke alarms on the market, you should form the habit of testing them at least once a month.

    Press and hold the test button on the smoke detector.

    Press and hold the ‘Test’ button on your smoke alarm until you hear the siren sound

    A broom handle will also work well for this test.

    If the sound is weak or nonexistent, you need to replace your batteries. This is relevant for non-mains-powered alarms. If the sound is weak or nonexistent from your mains powered smoke alarm, the entire smoke alarm will require replacement.

    How Often Do You Change Your Smoke Alarms

    Now that we know how often youd have to change smoke detectors, what about smoke alarms? Smoke alarms and smoke detectors may sound the same, but they are actually different when it comes to how they function.

    Smoke alarms are stand-alone devices that already have a sensor and an alarm built-in so that they can be used independently of an entire fire-prevention system in a home.

    Meanwhile, a smoke detector is a device that has a sensor that detects smoke but doesnt come with its own alarm system. Instead, it functions by signaling an alarm separate from it whenever it detects smoke coming from a fire. Smoke detectors work in conjunction with an entire system, and there is supposed to be a fire alarm panel that acts as the main power source for the smoke detectors.

    In other words, you can use a smoke alarm on its own while smoke detectors work in a system.

    However, the differences stop there. Whether or not smoke alarms still need to be replaced regularly is the same as a smoke detector. In that sense, smoke alarms have the same 10-year limit that smoke detectors do and should be replaced as soon as possible when that 10-year limit is up or when there are signs that would indicate that you need to get the smoke alarm replaced.
