query about LHS Cable (Linear Heat Sensor)

[TOMROLLINS]

Good morning everybody ...
I want to ask you about LHS Cable (Linear Heat Sensor) .. We are using it to detect any possible fire at the floating roof of our CRUDE OIL TANK. Now I have a problem that the (Cooper cable) thats connect LHS to junction box was damaged and I want to make a joint for it. my question is:
Is it possible to make a traditional joint using my hands only or I need a certified connector to do this joint ?

SENSOR CABLE SPLICING
The LHS sensor cable must be spliced or electrically connected
in a professional manner, in accordance with any
applicable codes or requirements. The recommended splicing
techniques described below do not preclude the use of
alternate means that are more suitable for a specific installation.
Because of the heat-sensitive nature of the sensor
cable insulation, soldering or heat-shrink tubing should never
be used when splicing LHS sensor cable.
Preferred Method - Using a junction box:
The preferred method for joining two lengths of sensor cable,
or for connecting sensor cable to copper lead-in wire, interThese
instructions do not purport to cover all the details or variations in the equipment described,
nor do they provide for every possible contingency to be met in connection with
installation, operation and maintenance. All specifications subject to change without notice.
Should furhter information be desired or should particular problems arise which are not covered
sufficiently for the purchaser’s purposes, the matter should be referred to KIDDE-FENWAL

connecting cable, or an end-of-line device, is to make the
connection inside a junction box.
1. The sensor cable can be joined using any industry standard
method for connecting copper conductors. Positive,
compression type connectors must be used, such
as wire nuts (3M/Highland H-30 or equal), butt splices
(Panduit BSN18 or equal), or a 2-position terminal block
(Molex/Beau C1502-151 or equal), following the
manufacturer’s installation instructions.
2. Any standard electrical junction box with a cover may
be used. In wet or damp locations, a waterproof box
must be used. The P/N 73-117068-027 Weather-Tight
Connector (or equivalent) must be used to provide strain
relief on the sensor cable where it enters the box. Do
not use “Romex” style cable clamps, as they may crush
the cable, possibly causing a false alarm.
Alternate Method – In-line Splice:
Where permitted by the AHJ, in-line splicing of two lengths
of sensor cable may be permitted. In-line splicing is not recommended
for connecting sensor cable to copper lead-in
wire, interconnecting cable, or an end-of-line device. In-line
splicing is also not recommended if the sensor cable is under
any significant tension.
When used for proximity detection, loop the sensor cable,
as the splice area does not provide detection coverage.
1. The sensor cable must be joined using nylon insulated
compression butt splices (Panduit BSN18 or equal).
Offset the two butt splices from each other.
2. Strip the jacket and insulation from each cable as shown
in figure 7.Trim the two conductors with the offset as
shown.

1/4” (6.4 mm)
1/4” (6.4 mm)

3. Crimp on the two butt splices as shown in figure 8, using
an approved crimp tool (Panduit CT-1550 or equal).

4. For dry locations, seal the splice by wrapping electrical
tape (3M/Scotch Super 33+ or equal) around the splice,
following the manufacturer’s instructions. Stretch and
overlap each turn of the tape by about 1/2 its width. The
tape should extend 2” (50 mm) beyond the ends where
the sensor cable jacket was cut. See figure 9.

5. For damp or wet locations, seal the splice by wrapping
silicon fusion tape (Tyco Electronics/Amp 608036-1 or
equal) around the splice, following the manufacturer’s
instructions. The tape should extend 2” (50 mm) beyond
the ends where the sensor cable jacket was cut.
See figure 9.
