SENSTAR OmniTrax - Severe Damage; Severe Damage (< 3 m)

Repairing sensor cables
OmniTrax Product Guide Page 159
1. Cut out the damaged section of cable, ensuring that at least 30 cm (12 in.) of cable is
removed.
2. Using a damp cloth and mild detergent, clean and dry the two cable sections thoroughly in the
area where the damaged section was removed.
3. Examine the cut ends of the cable for any signs of corrosion on the center conductor.
If any corrosion is present, strip back the cable until you reach uncorroded center conductor.
4. Classify the cable damage based on the length of removed cable. If removing corroded cable
resulted in an increase in the level of cable damage to severe, refer to the severe damage
section for additional information. See Cable damage assessment table
on page 156.
5. Install one male TNC connector each on the two cut cable ends and on both ends of the
replacement cable. See Installing connectors on OC2 sensor cable
on page 121.
6. Test the connectors for proper installation. See Cable tests
on page 146.
7. Slide on the two 30 cm sections of heatshrink tubing, and join the male connectors with female
couplers.
8. Position the two pieces of heatshrink tubing over the connectors and apply heat to seal the
heatshrink (see Sealing the heatshrink over decouplers/splices
on page 133).
9. Note the location and a brief description of the cable damage on the site plan.
Severe damage
The procedure for repairing detecting sensor cable with severe damage depends on the length of
the damaged section. For damaged sections up to 3 m (10 ft.) long, a replacement section of
detecting cable can be spliced in. For sections less than 3 m in length, it is not critical to match the
replacement cable’s graded foil opening with the damaged cable’s graded foil opening. Therefore,
any section of detecting cable may be used for this purpose. The OmniTrax long cable splice kit
(A4KT0302) includes two 3 m lengths of detecting sensor cable, for replacing damaged sensor
cable.
If the damaged section of detecting cable is longer than 3 m, Senstar recommends replacing the
entire sensor cable. If site conditions make this impractical, you must splice in a replacement
section of detecting cable in which the graded foil opening matches the graded foil opening of the
section of cable that is being replaced.
Severe damage (< 3m)
To repair severe cable damage that is less than 3 m (10 ft.) long, cut out the damaged section of
cable and splice in new cable. The long OmniTrax OC2 cable repair kit (A4KT0302) includes the
components required to make this repair.
