Smoke Alarm Going Off for No Reason

We must tell you that once you have a better understanding of a device, then you will be able to fix it quickly. Most of the devices can be fixed without any external help, but we should have its better understanding. What makes a professional different from us?

Both are available, and therefore you should know what type of smoke detectors you have, which keeps going off every 10 minutes.

Ionization smoke detectors have two plates separated by some distance. There is a continuous electrical discharge between the plates. When smoke enters the smoke detector and passes through the plates, it slows down the passage of electrical discharge by interrupting their flow. This process triggers the alarm and alarm goes off.

Photoelectric smoke detectors have a small light inside. Sensors surround the light. When smoke enters the photoelectric smoke detectors, it reflects the lights into sensors, which triggers the alarm, and the alarm goes off.

After reading about both, it does not detect smoke technically. It gets triggered by foreign objects, and alarms go off. This means that if somehow anything enters your smoke alarms, then it will go off till the things do not come out or get destroyed inside.
