Delta HLA – Groundwater

Delta HLA – Groundwater

The Delta HLA (Groundwater) is designed to detect high water levels within sump pump (submersible pump) chambers.

The Delta HLA is an independent high water level alarm with a clear display on the front fascia via LED, which acts as a warning system in the event of:

• power failure to the Delta HLA
• a high water level situation in the chamber/sump
• a high water level situation is recorded
• a service due

The Delta HLA offers a secondary line of protection in the event of mains power failure with a battery backup incorporated within the panel, ensuring continued protection.
