Are you being serious?
I remember years ago being called out to a system in the early hours that would not set. (Britannia Security!!)
It had 20 vipers on a single zone(!) and the installation guy had used the twist technique to loop in and out of the vipers.
Thanks for that - took me bloody ages to find the one twisted connection that was causing the problem.
I ended up going back the following day (working hours) to go round and solder all of the twisted connections, as I really didn't want another fun and games gig at 3am.
starting from the left hand side of the bottom pic
T = 6
- = 12v -ve
+ = 12v +ve
nc = 3
nc = 4
da = (do nothing with this)
T = 7
T = 6
- = 12v -ve
+ = 12v +ve
nc = 3
nc = 4
da = (do nothing with this)
T = 7
Personal preference then I suppose - if it works for you, then fine.
Fortunately, I no longer have to go out and rectify other people's (somethimes poor) workmanship any more.

NACOSS or SSAIB wont accept twisted joints, they have to be crimped or soldered.

Who cares what they want? Crimped joints are nothing but trouble. (and I've got a proper ratchet crimper)
So all the junction boxes that have been used over the years are no longer acceptable, when did this happen then?
If the wires are in a junction box and are held in the terminal between the nut and fastener then that is crimped or a terminal block etc ie either solder or a mechanical form of joint, not just twisted with a bit of tape over.
Play semantics if you like but cables held compressed under a screw head are not crimped in the accepted meaning of the term.
Anyway, twisted tape joints are not accepted.
I did not say that they were.
i've got my wires through & ready to go.
Can you please check that i've got this correct?
Thank you.
