Thanks for the replies
Sorry my second question was abit misleading haha
When the primary path fails (pstn) its has to be on a zone so the alarm is then in fault right??
And then if both paths fail a second zone is set up to create a fault??
G2- primary path fail
G3- both paths fail
Or am i making this up???
Sorry not pstn gprs/gsm

Very useful file and just what i was after. Just a couple of questions. Is the seperate tamper signal needed for both g2 & g3 installations?
Also am i right in saying you only need a single line path fault on a g2 and a single and full line fault on a g3?
