I have a 330A that gives an Stop Override Fault(90) whenever placed on fire service using the primary or secondary smoke detectors. Not 100% sure what causes this fault. Additional info for the fault give as code of 0x0000066. I do not know what code 66 means. Any insight on this would be appreciated.
Occurs when software detects that the Stop-Override switch is bypassed by a contact-short (RUEHC1,2.) Check CIOHNA hardware. Extra info: 65 Stop-Override relay stuck ON, 66 Stop-Override relay stuck OFF.
