Smoke Detector Does not function
-
- Dead batteries – Smoke alarms are powered by batteries which can die over time. Replacing the batteries may restore function.
- Disconnected power – Smoke alarms that are hardwired into the electrical system can stop working if the power is disconnected. Check the circuit breaker or fuse box.
- Build up of dirt and dust – Smoke alarms have small openings that can get clogged with dirt, dust, bugs, and other debris over time. Cleaning the alarms can help.
- Malfunction – Smoke alarms contain electronic components that can malfunction over time. If cleaning does not help, the alarm may need to be replaced.
- Improper location – Smoke alarms need to be located properly to function. If the alarm is placed in a spot with limited airflow or too far from a potential fire source, it may not activate properly.
- Missing or disabled batteries – Some smoke alarms have a battery disconnect or deactivation switch. Check to make sure the batteries are present and the deactivate switch is properly set to “on”.
- Age – Smoke alarms should be replaced every 10 years. Older alarms are more likely to malfunction.
- Damaged or broken alarm – Physical damage from drops or impacts can prevent a smoke alarm from working. Inspect for any visible signs of damage or distortion.
