I am dividing a room and want to either move the PIR or add another
PIR. Is this something that can be done easily or do I need to bring
in a professional. The system is a veritas with 8 zones 7 of which are
It depends who owns the alarm system, and if it's monitored.
It will probably require an engineer code (although I'm not
familiar with this alarm), and you won't have that if the
system is not owned by you or is monitored.

Ideally you would run another cable from the main control box to the new
PIR. It is not considered acceptable in the alarm trade to piggy back two
PIRs off the same zone.
You may need the engineers code to programme the new zone and an
installation manual to do this (I have the veritas manuals on pdf format and
my email works so ask if you need them)
Although you should not really join alarm cables to extend them, if you did
wish to do so then turn the mains power off to the alarm and remove its
battery. Solder and heatshrink the new cable to the old one and mount the
new PIR where you want.
PS Some Veritas systems use EOL technology so you cannot run 2 PIRs off the
If the existing pir is wired in 8 core then you should have no problem
wiring an extra zone using the 2 spare cores.
It is common practice to share 12 supply across 2 back to back devices and
as the veritas uses a global tamper loop rather than zone tamper you can
just series the tamper.
If the alarm is your's then you can easily remove the cover and even if you
do not have the eng' code your code will silence the alarm tamper.
Before starting work disconect the 12 aux supply at the panel or kill the
mains and remove the battery.(NB the earlier veritas 8's were prone to
crashing when repowered so power up by battery first.)
