Full details

The Marsh MA1HLA is an essential monitoring solution designed for property owners and maintenance professionals managing wastewater or drainage systems. It provides reliable, immediate notification of high-level conditions via a high-visibility beacon and audible buzzer, ensuring you can act quickly to prevent flooding or system failure. While the unit is highly effective at detecting potential overflows, it requires professional electrical installation to ensure the mains-power and battery backup systems operate according to safety standards.

FAQs

Can I use this alarm with an air pressure switch instead of a float?

Yes, the MA1HLA includes a 10-metre pipe specifically designed for connecting to an air pressure switch.

How long will the battery last during a power cut?

The integrated battery backup is designed to provide 48 hours of protection during a mains power outage.

Is this unit suitable for outdoor installation?

The system is designed for durability, but the main control panel should be mounted in a sheltered or weather-protected location.

Does this alarm reset automatically?

The alarm will stop sounding once the float switch or pressure switch returns to its 'normal' state, indicating the high-level condition has cleared.

Can I connect this to a home alarm system?

The MA1HLA is designed as a standalone alert system; for integration with other home systems, consult a professional installer.

Troubleshooting

The alarm does not sound when the float switch is raised

Verify that the unit is receiving power and check the wiring connections between the float switch and the control panel.

The unit fails during a power outage

Check that the internal backup battery is properly connected and has been charged; batteries should be replaced every few years if capacity drops.

False alarms triggering frequently

Inspect the float switch for debris or tether obstructions that may be preventing it from hanging vertically.

Pros and Cons

Pros

  • Integrated 48-hour battery backup for continuous security
  • Dual-alert system using both visual and audible warnings
  • Long 10-metre leads provided for flexible installation options
  • Rugged build quality suitable for long-term outdoor or utility use

Cons

  • Requires professional installation due to mains electrical requirements
  • Does not include remote telemetric monitoring features
  • Audible alarm may be difficult to hear in extremely noisy industrial settings

Setup, Compatibility & Care

Installation should be performed by a qualified electrician to ensure the mains connection is properly waterproofed and protected. The unit is compatible with the provided 10-metre float switch or alternatively an air pressure switch via the included 10-metre pipe. For ongoing care, periodically test the unit by manually lifting the float switch to confirm the alarm triggers correctly. Keep the beacon lens free of dust or debris to maintain maximum visibility, and ensure the battery backup remains connected to the internal terminal per the wiring diagram. Avoid exposing the main panel housing to direct, prolonged submersion, as it is designed for monitoring rather than underwater operation.
