Siren Marine Bilge Pump Sensor f/Siren 3

The Siren Marine Bilge Pump Sensor for Siren 3 Pro is a wireless monitoring system designed to track bilge pump performance and alert operators to abnormal activity before it becomes a safety issue. This compact sensor attaches directly to your bilge pump, creating a real-time data link that flags excessive run times or unexpected cycle counts—critical early warnings that something is wrong with your bilge system.

The system includes a wireless sensor module and bilge pump connector that pair with your Siren 3 Pro monitoring hub. The lightweight design (0.35 lbs) and compact dimensions (3 x 2 x 4 inches) make installation straightforward without adding bulk to engine compartments. By setting preset thresholds for run time and daily pump cycles, you establish a baseline of normal bilge behavior—any deviation triggers an alert, allowing you to respond to water intrusion, mechanical failure, or system malfunction before they escalate into emergency situations.

This sensor is essential for serious boaters, offshore anglers, and vessel owners who spend extended time on the water. Weekend fishermen who leave boats unattended between trips also benefit from the remote monitoring capability—you can check bilge pump activity from shore or dock without boarding the vessel. Bilge system failure is a leading cause of vessel damage and sinking; early detection through continuous monitoring transforms a potential disaster into a manageable maintenance issue. The wireless connection eliminates the need for running additional wiring through the boat's systems.

Compatible exclusively with Siren 3 Pro systems, this sensor integrates into Siren Marine's broader vessel monitoring ecosystem. Serious boat owners who already run a Siren 3 Pro system for engine monitoring, battery management, and overall vessel health will find the bilge pump sensor a logical extension of their onboard safety infrastructure.
