3 Reasons Why Hardwired Smoke Detectors Are Sounding
1. The battery is dead
When the battery is depleted, the smoke detector will alert you of the low battery status by continuously beeping. Simply replacing the battery with a new one can solve this problem.

2. Too much dust
Excessive dust accumulation can trigger false alarms, causing the system to shut down randomly. A thorough cleaning of the inside of the detector can resolve this problem. Before performing this step, be sure to turn off the detector at the circuit box to ensure safety during the cleaning process.

3. The detector is old and defective
Aging and defects are another major cause of noisy systems. Like any other piece of equipment, detectors degrade over time and begin to fail, especially if they have not been replaced for many years. Most smoke detectors have a lifespan of about ten years. After this, their function may begin to deteriorate.
