John, I have the installation manual in a pdf format but dated 2000. There is a difference, as the PCB layout differs, and I am myself attempting to obtain the manual for a version of the same alarm fitted in 1996.
I do also have the user instructions again as a pdf file and although again a later date, they do seem to match the original booklet I have. If you'd like me to send them please text or phone me on 07801 933766.
If you manage to get the installation manual for these early versions then I'd also be interested in them.
