1.1. Description
As RLE’s most cost effective distance-read leak detection solution, the SeaHawk 10K reports
the presence of water and other liquids as detected by sensing cable.
Capable of accommodating up to 10,000 feet (3048m) of sensing cable, the SeaHawk 10K has
an audible alarm and can communicate via Modbus. As a stand-alone solution, the
SeaHawk 10K provides alarm notification and numeric distances on its front panel.
Integration into a Modbus network allows the activity and status of one or multiple
SeaHawk 10Ks to be managed from one central location.
1.2. Operation
Supervised System
The SeaHawk 10K is a supervised system – it continually monitors sensing cable and spot
detectors for continuity – and produces alarms for the following conditions:
♦ Leak detection
♦ Cable break
♦ Cable contamination
Distance-Read Leak Detection
When the SeaHawk 10K's circuitry measures a current in excess of the user-defined leak
threshold, the unit's microprocessor computes the distance to the leak. The SeaHawk 10K then
annunciates the leak and communicates via Modbus to a master controller or a Modbus-
equipped monitoring system. The summary relay sends notification to an alarm panel or
monitoring system.
