Delta HLA – Groundwater (High Level Alarm)

Delta HLA – Groundwater (High Level Alarm)

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.
