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

      Cynthia RodriguezAug 2, 2025
      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.

      Sandra LeeAug 8, 2025
      If your General Monitors FL3100H Smoke Alarm constantly signals a 12 mA signal even when there's no known radiation, it might be detecting background UV radiation. Cover the UV portion of the FL3100H for ten seconds to see if the signal stops. If it does, eliminate the UV radiation source or move the FL3100H. If the signal continues, you may need to replace the UV detector tube.

    Why is the green LED blinking slowly on my General Monitors Smoke Alarm?

      Michael SampsonAug 14, 2025
      A slowly blinking green LED on your General Monitors Smoke Alarm, accompanied by a 2 mA signal, often indicates a COPM FAULT caused by a dirty or obscured optical path. You should clean the UV and IR windows, as well as the associated source light rods.

    What to do if General Monitors Smoke Alarm has no output signal and the green LED is rapidly blinking?
    • M
      Mr. Devon HarrisonAug 19, 2025
      If your General Monitors Smoke Alarm shows no output signal and the green LED is rapidly blinking, it's likely due to a low voltage fault, meaning the voltage at the unit is less than +18 VDC. Ensure the unit receives at least +20 VDC under load.

    How to fix General Monitors Smoke Alarm with no output signal and the green LED is off?
    • R
      Rachel NelsonAug 26, 2025
      If your General Monitors Smoke Alarm has no output signal and the green LED in the UV window is off, the unit may not be receiving DC power. Ensure that +24 VDC is correctly applied with the correct polarity.
