OK... you referred to "Running cable inside a roof cavity will need a licenced cabler" so yes, on that basis I did assume there was some element of that involved.
Yes, there are some restrictions in the rules/standard. Any hard-wired installation requires the installer to be a licensed cabler.
If for example, you connected some sensors (or cameras) with off-the-shelf pre-terminated cables and you attached those cables to a surface (wall, floor, ceiling, etc) they become, by definition, 'fixed'.
The same applies if you pass a cable through a wall, cabinet, frame, ceiling, wall, under carpet, etc... and part of it is concealed, then it too is considered by the rules to be 'fixed'.
In the case of a fully-wireless alarm... if it connects to, or may at any time in the future, connect to a telecommunication carrier's network (monitored alarm, dialler, etc) it is required to be installed by a licensed cabler, as there are still segregation distances within the rules that must be complied with... eg: mandatory separation distances from other services... power, gas, water, other cabling, etc.
I don't make, or enforce the rules... I'm just required to adhere to them.
Just giving you a heads-up on what's involved.
It's worth noting that insurance companies love to find ways out of paying claims and if there's a fire for example and investigators find an alarm system installed without a Telecommunications Cabling Advice signed off by a licensed installer, they 'may' consider it to be a contributing factor... especially if segregation requirements haven't been met.
It's no different to DIY electrical work in that regard.
