I am fitting a new Texecom alarm in my house. The cable I am using
is
6 core and has yellow, red, green, blue, black and white strands inside.

Are there any wiring colour conventions for fitting the PIRs, door
sensors, keypad etc?

Thanks

Not sure it is a good idea to stick to a convention even if there is one -
makes it easier for someone to cut the cables and disarm sensors! I would
just devise my own wiring colour scheme if installing from new, but I did
follow the existing one when altering an our existing installation.
