Warning Chime Characteristics

Each warning chime has unique characteristics that help identify and differentiate one warning chime from another. The warning chimes use volume, chime frequency, length of time the chime sounds and the number of chime tones to identify which chime is sounding. The IPC prioritizes the chimes according to a preset hierarchy programmed into the IPC software. Generally, when more than one chime request is received by the IPC, the most important chime sounds. If a lower priority chime is currently sounding, the higher priority request takes over and replaces the lower priority chime.

There are 3 different chimes as listed below:

The following table provides a summary of the chime characteristics including the chime priority:
