How to Check Smoke Detector

In this article, we will discuss how to check a smoke detector to ensure it’s functioning properly. We’ll explore the 4 necessary steps, including visual inspection, testing the alarm, checking for expiration, and replacing the batteries.

Visual Inspection

Start by examining your smoke detector visually. Look for signs of physical damage like cracks, soot, or dust buildup. Make sure that it’s securely attached to the ceiling or wall. A damaged or loosely attached smoke detector may not function properly in case of a fire.

Test the Alarm

Press the test button on your smoke detector. This should trigger the alarm, causing it to emit a loud noise. If it doesn’t, it may indicate that the detector isn’t working correctly, and you may need to replace the batteries or the entire unit.

Check for Expiration

Smoke detectors don’t last forever. Most models have a lifespan of around ten years. To find out if your smoke detector is expired, look for the date of manufacture on the device. If it’s more than 10 years old, it’s time for a replacement.

Replace the Batteries

If your smoke detector is not sounding an alarm during the test, the problem could be as simple as dead batteries. Even if the alarm works, replacing the batteries at least once a year is a good idea. Some models start beeping intermittently with low battery power, indicating it’s time to replace them.
