Why doesn't my Gemini or Magnum Alert MA3000 control panel indicate a trouble immediately after I disconnect the battery leads?
If you disconnect one or both battery leads inside a Gemini or Magnum Alert MA3000 control panel, the low battery indication may take up to 4 hours to annunciate at the keypad. This delay is because the control panel may require up to 4 hours to perform an automatic dynamic battery test.
The dynamic test may be initiated manually by pressing the RESET button, or it will be initiated automatically, every four hours, by the control panel. A low-battery system trouble will annunciate at the keypad if the control panel ever detects that the battery terminal voltage has dropped below normal (11.5VDC). A trouble restoration will not occur until the control panel detects that the battery is reconnected, providing normal voltage and passes a dynamic test.
