What to do if General Monitors Smoke Alarm constantly signals 16 mA or 20 mA with no radiation?

If your General Monitors FL3101H Smoke Alarm constantly signals a 16 mA or 20 mA signal (WARN or ALARM) even when there's no known radiation, it could be due to background UV radiation affecting the detector. To check this, cover the UV portion of the FL3101H for ten seconds. If the signal stops, remove the source of UV radiation or relocate the FL3101H. If the signal persists, the UV detector tube in the FL3101H may need replacement.
