Audible Breath Beep

When the detected CO
and the audible breath beep will sound. One beep is sounded for each breath detected. The breath beeps
will only sound during the quiet part of an alarm burst sequence.
The "variable pitch" (fixed pitch "off") breath beep is the default setting at setup. During variable pitch
breath beeps, the tone of the breath beeps is indexed to the number of bars illuminated on the CO
graph. The more bars lit, the higher the pitch. In variable pitch mode, breath beeps will sound at
inspiration (on the falling edge of the CO
However, if desired the "fixed pitch" breath beep (fixed pitch "on") can be selected at setup. The "fixed
pitch" breath beep has a pitch higher than the highest bar graph-indexed pitch. In fixed pitch mode,
breath beeps will sound during exhalation (on the rising edge of the CO
initialization and when changing the breath beep sound volume, beeps will sound as fixed pitch.
Each time the 9847 is turned on, the audible breath beep will default to the medium sound volume setting.
During normal operation, pressing the advance switch cycles the audible breath beep sound volume
between low, medium, high, and off. A "volume" beep will sound each time the advance switch is pressed
to indicate the current setting, unless an audible alarm is in progress.
NOTE: The advance switch will not alter the volume of the medium and high priority audible
alarms.
