The Delta HLA – High Level Alarm for Basement Pumps – New Model

Description
The Delta HLA – Groundwater is designed to detect high water
levels within packaged pumping stations and sumps.

The Delta HLA is an independent high water level alarm with an 85 dB audible
alarm and LED status display on the front fascia.

It acts as a warning system in the event of:
• power failure to the Delta HLA
• a high water level state in the chamber/sump
• a high water level state has been recorded
• a service due

The Delta HLA provides a secondary line of protection in the event
of mains power failure. Its internal battery ensures continued
operation of the alarm until mains power is restored.

The Delta HLA is simple to install and offers three volt-free contacts
for connection to external systems.

The Delta HLA operates via mini float switch. If the water level rises
above the start point of the primary pump, the alarm float switch
lifts until a point of contact is made internally. This signals to the
panel that the water level is high and the panel goes into alarm.
When the level drops, the switch falls which resets the alarm.

The mini float switch is mounted to a Delta Float Shroud and fixed
to the internal pipework by cable ties.

For areas where the Delta HLA may not be seen or heard, we
recommend using the Delta HLA Plus.
