hi guys hope you can help........i've wired my shed up to the house alarm(accenta G3) using a door contact,i've used zone 5 on the panel.i've tried to program zone 5 by pressing PROG then 9999.pressing 5 then 1 then 5 again,then reset 3 times to come out of the installation.but for some reason when i set the alarm zone 5 is not working...i've checked the wiring and that fine!When i put zone 5 on chime the alarm recognizes it so the door contact on the shed must be ok.i just cannot understand when the alarm is set,zone 5 will not work please please can someone tell me were im going wrong!feel like burning the shed down cheers aidan.............
