Bilge Alert - High Water Alarm with Sensor

The Bilge Alert high water detection alarm utilizes the patented Mirus™ field effect technology to detect presence of liquid. The detector is highly reliable, durable and takes advantage of advanced sensor technology. Totally sealed fluid detectors are never in contact with water, will not corrode and are not affected by oil or debris. The detector activates an alarm of 100 db after a delay of 8 seconds after being exposed to water. Three way rocker switch allows alarm to be tested, turned off and armed (Test-Off-Armed).

The Bilge Alert sensor should be mounted on the bulkhead, stringer, inner transom or hull of your boat above the normal operating level of your automatic float switch, but below the level of critical components of your boat and/or engine; such as the starter.

The sensor measures a small 26 mm wide x 64 mm long x 5 mm thick (1.04 x 2.5 x 0.2 in) which makes it very easy to mount
