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.
