I've got a system we installed 10 years ago that includes a QSG-6P120 6 zone Grafik Eye and (2) 2 button keypads. I've added a 7 button keypad to the system and went through the local programming to set it for zones 1-7 but it doesn't seem to work. Anything specific I'm missing here? It enters programming mode, I save the settings on the Grafik Eye, it exits programming mode, I can then select the scene buttons 1-7 but they don't do anything. The Grafik Eye and 2 other keypads still work fine.Thank you, John
