Cabling
Joining Cables
Regular inspection of the cabling for damage from
insects, animals or machinery should be carried out.
If necessary the cabling can be trenched (with or
without conduit) or elevated away from potential
damaging elements.
The following describes the method used for
repairing damaged cable;
1.
Insert the cables into a two-way junction box and
pull through enough cable to make joining easy
(approx 50cm).
2. Strip back the outer sheath of the cable so that
5cm of inner cables are exposed. If transmitters
and receivers are not being used in the system
then cut back the white cable.
3. Insert the cables to be joined into the 3M
Scotchlok connectors (Sentek part number 80100
Scotchlock, 2/4 wire cable) and crimp. To do
this hold the connector with the button side down
and insert the wires all the way into the ports and
then crimp the button fully. Ensure that the
cables are fully inserted into the gel-filled
connectors prior to crimping. Failure to do this
may
result in unreliable connections.
Note: Sentek recommends joining each wire in
the cable, even if the wire is unused.
4. After all connections have been made pull back
the cables so that 5-10mm of the outer sheath
protrudes from the cable gland. Tighten the cable
glands.
5. Tuck the connections into the box and attach the
top cover.
SLA battery
The SLA battery supplied with the Sentek RT6
System has a typical life expectancy of 1 to 3 years.
The life of the battery is effected by number of
discharges, depth of discharges and operating
temperature. When the battery does not hold charge
