Seller's factory or for preparation work for field repair or replacement. Invoicing of Seller for labor either
performed or subcontracted by Purchaser will not be considered as a liability by the Seller.

The liability of Seller hereunder is limited to replacing or repairing at Seller's factory or on the job site at
Seller's option, any part or parts which have been returned to the Seller and which are defective or do not
conform to such specifications, drawings or other written descriptions; provided that such part or parts are
returned by the Ultimate Purchaser within ninety (90) days after such defect is discovered. The Seller shall
have the sole right to determine if the parts are to be repaired at the job site or whether they are to be
returned to the factory for repair or replacement. All items returned to Seller for repair or replacement must
be sent freight, prepaid to its factory. Purchaser must obtain Seller's Return Goods Authorization prior to
returning items. The above conditions must be met if warranty is to be valid. Seller will not be liable for any
damage done by unauthorized repair work, unauthorized replacement parts, from any misapplication of the
item, or for damage due to accident, abuse, or act of God.

This warranty shall be exclusive of any and all other warranties express or implied and may be modified only

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.

CHAPTER 0PRODUCT OVERVIEW

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 Modbus­equipped monitoring system. The summary relay sends notification to an alarm panel or
monitoring system.

rletech.com SeaHawk 10K User Guide 11

1 Product Overview

User Configuration and Communication

The SeaHawk 10K’s front panel display – which includes a four-digit LED panel and six LED

indicators – provides information about its status, including the following:

♦ Leak detected

♦ Cable fault detected

♦ Power status

♦ Configured unit of measure

♦ Leak detection cable’s amperage value

♦ Distance to leak or contamination

♦ Length of installed leak detection cable

♦ Self-test results

The two blocks of DIP switches on the SeaHawk 10K’s front panel are used for configuration.

DIP SW1 configures parameters such as leak and contamination thresholds, latching alarms,

and realarm time interval. DIP SW2 is used to set the Modbus address information for the unit.

The SeaHawk 10K also provides configuration capability and status information to a Modbus-

equipped system via its EIA-485 port.
