We can't give that info out
But it seems when you disconnected your sensors you havnt connected them back correctly
As said "above" you have problems with zones 2-7 possibly
If you didn't mess with wiring in control panel that should be ok
But zone 1 is a door contact yes? So won't help you to wire the pirs
Each pir will have a negative and positive sometimes it's red and black sometimes it isn't , but if your saying in the panel all of them are connected to +'ve then you need to check what you did in your pits again
Why don't you load some pictures of each pir here ?
