Chime Warning

When more than one condition requiring a CTM-generated audible warning is present, the CTM will stack the warning conditions and sound them in order of decreasing priority according to the table provided. However, the CTM will not delay the illumination of any warning indicator lamp, even in cases where its associated audible warning is being delayed by the sounding of a higher priority audible warning. For any given condition requiring an audible warning, the CTM will sound that warning only after all higher priority warnings have completed sounding, the given condition still exists, and the associated indicator lamp, if any, is still illuminated.
