Is the cable on show? If so, soldering and sleeving carefully using heat

A choc strip isn't tamper proof. Solder and sleeving is as tamper
proof as the cable.

Use a proper alarm cable jointing box. Terminal for each wire and a
tamper switch that operates when you take the cover off.



Do you know how easy it is to take the cover off one without activating
the tamper switch if you wanted to? The same goes for bell boxes and
alarm panels.

I'd guess any ner-do-well who was into tampering with alarm wiring would
be well aware of the easiest ways to do it. And it's not that difficult to
get at the conductors inside a cable run anyway, when you don't care about
how much damage you might do.


Its more difficult with modern systems, they can use end of line
terminations so they can detect cuts, shorts and changes in resistance.

The old Chubb systems I used to work on 40 years ago were easy to hack
if you knew how.
