A fire alarm keeps beeping mainly due to these reasons:
- Low Battery: The most common cause is a low or dying battery. The alarm beeps as a warning to replace the battery soon.
- Dust and Debris: Dust, cobwebs, or insects inside the alarm sensor can block its detection ability, causing false beeping.
- Aging Smoke Detector: Smoke detectors typically last about 10 years; after that age, they may malfunction and beep.
- Interconnected Alarms: If multiple alarms are interconnected, a malfunction or false trigger in one can cause all to beep.
- Electrical Issues: Loose wiring or power supply problems can trigger intermittent beeping.
- Environmental Factors: Heat, humidity, or incorrect placement near kitchens or bathrooms may cause false alarms.
Checking and replacing batteries, cleaning the alarm sensor chamber, ensuring proper placement, and replacing old alarms typically resolve beeping issues.
