[Ticket Question] Help with an ADE GEN4

[securitywarehouse]

hi i have just installed this panel

to an exsisting system, it has 1 door entry contact and 2 pirs 1 on the route to the panel the other at the back of the house.

i conected the door contact to zone 1

the pir on route to the panel on zone2

and the other to zone 3 i am using program 1 and set zone 2 as timed inhibit

the problem im having is when i do a walk test zone 1 triggers zone 3 and visa versa zone 2 triggers on its own fine.

so if i set the alarm as i trigger the door contact (zone 1)before i get to the panel the alarm activates so i enter the code to silence and zone 1 & 2 are solid and 3 is flashing

the door contact is only 2 wir so i cant have wired it up wrong

any idea what i have done wrong?
