The HWAB indoor high water alarm is designed to
warn of high water levels in lift chambers, sump basins,
holding tanks, sewage and water removal systems.
When a potentially threatening liquid level condition
occurs, the alarm horn will sound and the alarm light
will illuminate. The alarm light will remain illuminated
until the condition is remedied. Once the condition is
cleared, the alarm will automatically reset.
A green “power on” light indicates 120VAC primary
power is being applied to the alarm. The alarm is
equipped with a 9VDC battery backup to ensure the
alarm system continues to function if primary power
fails. If battery is low, a low battery chirp feature will
cause the horn to chirp approximately once per minute.
This indicates that the battery should be replaced.
