audio alarm will activate. Set the release point
depth below the trip point to turn the alarm off as
the water level falls and returns to normal. A
release point set above the trip point will be
ignored but the alarm may "hunt". Set the audio
alarm on or off. If no HIGH LEVEL ALARM is
required, set the trip and release values higher
than the sensor length and the audio to off.
3.7.3. Program a LOW LEVEL ALARM by setting the
trip point at the desired depth. As the water level
falls below that depth the red LED and the audio
alarm will activate. Set the release point depth
above the trip point to turn the alarm off as the
