I recently fitted an alarm optima G4, on completion i found that the alarm kept going off on entry time out it keeps showing that zone 3 is at fault but on the entry door is zone 1 and zone 3 is the dining room in another room not any where near the entry door. so i changed the zone to 4 and the same thing happened, going through the program all was set up ok, so i spoke to Honeywell technical and they told me it was a fault that in the program on the G4 panels and that 4 zones had to be use in the panel for it to work, so if only 2 or 3 zones are used then the other zones must be linked out but not set as used in the program so a total off 4 zones are used for the panel to work,the next panels will be sorted so they work as normal
