Supplies for Installation

Included with the X-Connector

X-Connector device

Two end-of-line terminators (EOL)

Available from RLE, sold separately

SeaHawk Sensing cable

SeaHawk Non-sensing cable

SeaHawk SD-Z Spot Detector

SeaHawk Leak Detection Controller

X-Connector Functionality

The X-Connector uses internal, fi xed resistors to simulate 50 feet (15.24m) of

sensing cable per branch for Branch 1, Branch 2, and the Output. This creates a

buffer between the branches of the X-Connector, and eliminates confusion when

leaks occur at the beginning and end of the branches.

Even if you connect an EOL to the branch, the system will still interpret that

branch as using 50 feet (15.24m) of cable. Overall, the X-Connector simulates

150 feet (45.72m) of sensing cable.

X-Connector Quick Start Guide

Thank you for purchasing a SeaHawk X-Connector. This guide describes how to install the

X-Connector in a SeaHawk leak detection system.

Cable and Spot Detector Connections

Each branch of the X-Connector can accommodate sensing cable, non-sensing

cable, or an SD-Z spot detector. EOL terminators can be connected to Branch 1,

Branch 2, or the Output branch. Follow these steps to connect the appropriate

device to the X-Connector:

1. Connect the cable running from the controller - whether it’s the leader cable

that comes with most SeaHawk controllers, sensing cable, or non-sensing

cable - to the connector marked Input.

2. Connect

your

fi rst device - sensing cable, non-sensing cable, an SD-Z spot

detector, or an EOL - to Branch 1. Please remember, 50 feet (15.24m) of

cable is simulated between the Input branch and Branch 1. If you’re using

the device in conjunction with a distance-read controller, you’ll need to

account for this simulated length. Add 50 feet (15.24m) to the cable length

reading at the beginning of Branch 1. The diagrams on the back of this

sheet may clarify this concept for you.

3. Connect your second device to Branch 2. On distance read systems, add

50 feet (15.24m) from the Branch 1 cable end distance to the beginning

distance of Branch 2.

4. Connect your third device to the Output connector. On distance read

systems, add 50 feet (15.24m) from the Branch 2 cable end distance to the

beginning distance of the Output connector.

IMPORTANT - If you are not going to connect cable or a spot detector to a

particular branch connector or the output connector, you must attach an EOL

terminator to that branch. Without the EOL, your controller will report a cable

break. When you attach an EOL, you still must account for the 50 feet (15.24m)

of cable simulated by that branch.

Know your cable!

RLE’s orange sensing cable has a resistance of 2.8 ohms/foot. At this

resistance, the X-Connector’s internal resistors simulate 50 feet (15.24m)

of cable between branches.

Other sensing cable has a resistance of 4.0 ohms/foot. At this resistance,

the X-Connector’s internal resistors simulate 35 feet (10.67m) of cable

between branches.

Please verify your cable’s resistance before you program your leak

detection controller. If you have questions about the resistance of your

cable, refer to the cable’s data sheet.
