High Water Safety Alert System - 24V / 10A Max
The Seaflo WAS21002 is a critical safety integration for any 24V marine vessel. This comprehensive kit monitors unmanned bilge compartments, providing both a high-decibel audible buzzer and a bright red LED visual warning the moment water levels exceed safety limits. Engineered for harsh marine environments, the included float switch features a dedicated filter housing to prevent debris from interfering with operation.

Is this a genuine original part?
This is a genuine SEAFLO manufactured safety system, supplied in original retail packaging with full technical documentation.
How do I know if it is compatible?
This kit is specifically designed for 24V DC systems. If your boat electrical system is 24V, this is the correct SKU. For 12V systems, please look for the WAS12002 model.
Can I add more switches to one panel?
Yes, the system is expandable. You can wire additional Seaflo float switches (such as model SFBS-12-04B) in parallel to monitor multiple compartments through the single WAS21002 alarm panel.
Note: Professional installation is recommended. Ensure all wire connections are kept above the highest potential water level for safety. Visit 4boats.co.uk for further marine equipment.
