Yes but correct as it is , the viper is triggering before the hallway that's why F is present
Maybe swb means viper zone 3 is triggering and some how when you enter hallway your triggering the hallway although it should be entry zone
So zone2 red herring and zone 3 is the actual problem
If you get me , cos I don't lol
If your getting the same activations , meaning both zones ,are they following the same route or sharing a common cable , perhaps there is a fault
Cable damaged , mice , rats ,carpet fitter etc
