How Long Do Smoke Detectors Last?

As soon as a smoke detector begins chirping at regular intervals, every homeowner should recognize it’s time to change its batteries. So, when is it time to replace the smoke detector entirely? Let’s see what you should know about the lifespan of smoke detectors.

How Long Should Smoke Detectors Last?

Today, the majority of manufacturers recommend replacing a smoke detector every 10 years. However, if the smoke detector shows any signs of malfunctioning, it’s time for a replacement.

Thankfully, there are several noticeable signs homeowners can look for to determine if a replacement is needed. For instance, if the alarm goes off randomly, chirps endlessly, or the test button works improperly, you may need to replace the detector.

Signs You Need To Replace A Smoke Detector

There are several things that can indicate a replacement is needed, as outlined below.

Chirping

While a smoke alarm may undoubtedly chirp for battery replacements, it can also do this for other reasons. If it’s time for a replacement, you may notice issues with increased sensitivity.

Increased sensitivity may be noticed if the detector chirps simply due to temperature changes or the buildup of dust.

Going Off Randomly

You will need to replace the smoke detector if it starts going off for no reason at all. The test button may also fail to work, at this time.

Be mindful if the detector doesn’t beep at all, beeps too quietly, or fails to beep after pressing the test button.

Yellow Discoloration

If a smoke detector features any sort of yellow discoloration, it’s a clear sign it’s time for a replacement. A detector can turn yellow as soon as the flame-retardant bromine material degrades within the alarm’s casing.

While this won’t impact its functionality, it does indicate the unit has been up for quite some time.

Risks Of Using Expired Smoke Detectors

Using an expired smoke detector is ultimately equivalent to driving a car with worn brakes. If there’s a real emergency, the risks will multiply quickly.

Older sensors are less sensitive, meaning they will take longer to detect smoke or fumes, putting everyone in danger. False alarms or malfunctions can lead to uncalled-for panic or damage in the worst case scenario.

Failing to work during critical moments can lead to indescribable loss. Any of these issues could come with catastrophic outcomes. Contact the team at Shield’s Electric with any smoke detector-related questions.
