seriously pirs on the exit route set to guard access and they should work, if you have been playing with the attributes, get to the keypad, go to zone setup, go to the zone and put the zone to not used and then back to guardaccess and leave alone do this for the zones affected and then try again.
If a guard zone is active during the set it will say that its preventing it from arming a guard access wont as it is expected to be active as its on the exit route.
Sounds like you need professional help to look into what is happening as the whole story just isn't there at the moment.
