Test the SeaHawk Sensing Cable and Controller

Before you lay any SeaHawk sensing cable in an installation, it is wise to connect the cable to the controller and ensure proper

communications.

1. Attach the leader cable to the controller.

2. Connect the sensing cable to the leader cable.

3. Attach the end-of-line terminator to the end of the last run of sensing cable.

4. Turn on the controller and test the sensing cable. The easiest way to test the cable is to pour a 2” (5cm) puddle of

water on the floor and put a strand of sensing cable in the puddle. If you’re not able to pour a puddle of water on the

floor, wrap a clean damp cloth or paper towel around a small section of cable. Do not hold the cloth or towel with your

hand - this creates uneven pressure on the cable and can cause erratic readings on distance read controllers. Once the

cable is dampened, the controller should alarm within a reasonable time. This time may vary depending on controller

type and the alarm time frame set within the controller.

Do not saturate a section of cable - the cable will go into alarm with a very small amount of water, and if you saturate

the cable fully, it will take a longer for the cable to dry and the alarm to reset.

5. Once the cable passes the initial test, proceed to the sensing cable installation.

Install SeaHawk Sensing Cable on Floors

SeaHawk sensing cable is durable, flexible, and designed to mitigate false alarms. While installation is fairly straightforward - lay

the sensing cable according to the preconfigured layout on your map and secure the sensing cable to the floor with J-clips - keep

the following guidelines in mind to avoid complications:

• Do not install sensing cable that is damaged or dirty - while the cable is designed to mitigate false alarms, visibly dirty

cable will need to be cleaned before installation. If your sensing cable needs to be cleaned, refer to the Sensing Cable

Care and Maintenance Guide.

• Do not run sensing cable through contaminants - ie. dirty or greasy areas. The floor must be clean of contaminants for

the sensing cable to function properly and for J-clips to adhere. If necessary, clean the floor before installation.

• Avoid laying sensing cable in the direct downstream of air conditioning units - these units discharge moisture, which will

skew leak detection readings. Place the cable 4 to 6 feet (1.2 to 1.8m) away from air conditioning units to avoid false

alarms and contamination.

• Tools or heavy objects can damage sensing cable. Avoid rolling, dropping, or setting heavy items on sensing cable.

Whenever possible, install sensing cable out of the way of foot traffic.

• Use J-clips to secure the sensing cable. J-clips are nylon cable clips with a self-adhesive backing. J-clips hold sensing

cable securely in place without pinching or binding the cable, which can cause false alarms.

• J-Clips should be placed 5 to 6 feet apart throughout an installation, and 3 feet apart when cable is routed in front of

CRAC units. Because the J-clip’s adhesive backing does not work well on porous concrete floors, apply a drop of silicone

or another nonconductive adhesive to help secure the J-Clip to the floor.

• Ensure the sensing cable is installed directly on the floor, and there are no gaps between the cable and the floor. Use

additional J-clips as necessary to avoid large gaps.
