Little Giant - 513288 - HWAB Indoor High Water Alarm

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.

Stop! Required before ordering:

Unless specified above, all pumps are for water use only and are not to be used for any other purpose.

If you are selecting a pump that is designed for pumping products other than water, please check the chemical resistance chart to determine if your pump is fit for your purpose, application and that the pump and seals are compatible for your use.
Warranty is subject to the proper selection of material and seals of the product you are pumping.
