It’s possible that there could be a few reasons for this problem. Firstly, I’d recommend checking if the smoke detectors are properly installed and not obstructed by any objects. Additionally, ensure that the detectors are clean and free from dust or debris, as this can interfere with their functionality. If the issue persists, it could indicate a wiring problem or a fault in the panel itself. In such cases, it’s best to contact a certified technician to inspect and troubleshoot the system further.
