Hi I have an old ademco 330 in my house. I have no idea how to use it. I has a key switch outside the house (not even a keypad!). it has alarm boxes mounted on house (front and back). It has no off switch! it has emergency buttons in hall and bedroom (in case I get visited by freddy kruger I guess). Can anyone help me :( Thanks CP

I am installing a Vista 20P with 2 keypads, a 6160V and a 5160RF and have had no problem installing the 6160v as the main keypad on 16. I have registered another keypad on 17 with the 6160v but I can't get the 5160 RF to do much of anything. I have repowered and held down the appropriate keys and I get No AC ( I know I don't have a backup battery) and Not Ready and it flashes Add, 31 and then dE. I have checked the wiring and it is correct and I have tried everything I can think of but can't get it to display anything else. I can't change the code to 17 or anything. Any advice would be greatly appreciated. Thanks in advance for your time.
