The Johnson Pump Marine Bilge Alert™ High Water Alarm with Ultima Switch provides reliable electronic high-water detection for bilge areas. Using Mirus field effect technology, the sealed detector cell senses the presence of water and activates a 100 dB piezo alarm with a visual LED warning light. With no moving parts, no mercury and completely sealed corrosion-proof electronics, the system is designed for dependable performance in harsh bilge environments. Its compact detector footprint allows flexible installation, while the three-way switch can disable the audible alarm during maintenance while keeping the LED warning active. Available in 12V and 24V models.
