Clean SeaHawk Sensing Cable
While SeaHawk sensing cable is engineered to resist contamination from dirt and dust, RLE does recommend periodic cable
maintenance. This keeps your cable free of foreign particles and ensures the fastest, most reliable leak detection response.
There are two preferred ways to clean SeaHawk sensing cable:
Clean the Cable with Isopropyl Alcohol
Cleaning the cable with alcohol allows you to clean the sensing cable without completely removing it from its installed location.
You’ll remove the section of cable you wish to clean from its J-clips, wipe it down, and reinstall the cable. This method will clean
most contaminants from the cable, and will sufficiently clean the cable in many cases.
1. Obtain a dye-free heavy cloth rag and a bottle of isopropyl alcohol.
2. Remove the first section of cable to be cleaned from its j-clips.
3. Soak the rag with alcohol.
4. Wrap the rag around the cable and squeeze firmly while pulling the rag down the length of the cable.
5. Flip the rag every several feet. Resaturate the rag with alcohol as required.
6. Once you’ve reached the end of the first section of cable, place it back in the J-clips and proceed to the next section.
7. Replace the rag if it becomes too dirty.
Clean the Cable with Warm Soapy Water
If you still notice problems with your sensing cable after you’ve cleaned it with isopropyl alcohol, or if you believe the cable is so
dirty that it requires a more intense scrubbing, clean the cable with warm soapy water. This process requires you to completely
remove the cable from its installed location, submerge it in a soap and water solution, scrub it with a brush, and hang it to dry.
1. Remove the sensing cable from its installed location. To help with the reinstallation process, you may want to label the
sections of cable or note their location.
2. Gather Dawn dish soap, a large bucket or plastic bin, warm water, soft-bristled scrub brushes, and clean rags.
3. Locate an area inside or outside your facility that will not be affected by water.
4. Add dish soap to a bucket of water. Use about 1 cup of detergent to 1 gallon of warm water. To determine if your
solution is concentrated enough, place your finger and thumb in the water and rub them together. You should feel a
slick/slimy residue. If you do not feel a residue, add more detergent to the water and gently mix to distribute the soap.
5. Submerge a section of the cable in the water.
6. Using a scrub brush or rag, scrub along the surface of the cable with firm pressure. Scrub all sides of the cable.
7. Remove the section of the cable from the soapy solution and rinse it in a bucket of clean, fresh water.
8. Ensure there are no oily deposits along the length of the cable. If the cable does not appear clean, repeat steps 6 and 7.
9. Hang up the cable to dry. Try to point the connectors down, so water cannot pool inside the connectors. The drying
process may take 6 – 48 hours, depending on the room conditions.
10. Once the cable is completely dry, reinstall it in its original location.
SeaHawk Sensing Cable FAQ
Question Response
How do I secure sensing
cable to the floor?
RLE recommends the use of J-clips. 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.
