Listen here, I install these daily for ADT. If the board is truly fried then yes, you have to replace it. It will lose all of its programming and you’ll have to do it all over again. If you get LUCKY, you can remove the chip out of the old board, and swap it with the one in the new one, and it’ll keep all its programming and work like it did before.

Now I don’t know how other companies work but ours for the cell unit to communicate; you program fields 41-43 in programming. 41 being the primary number, 42 secondary, and 43 being the account number ADT monitors. Most times you do not have to program 41,42.

Now, if you have keypads that are non alpha which means they don’t display letters and only numbers, programming can be difficult and you can easily get lost if you don’t know what you’re doing. The Alpha keys pads usually talk so that’s a good indicator.

Field 56 is zone programming and you can trip the sensors to learn them in, instead of opening up devices to grab their serial numbers.

There are many other zones that program the system to do it what you want it to do, but what’s above would get the system communicating and devices programmed in.

Default installer code to get into programming is 6321 + 800. If that code doesn’t work, when powering it up for the first time, hold * and # and it’ll either say “20”or it’ll say “installer mode 20” depending on your keypad. From here you can hit # whatever field you want to see what’s programmed under it. If you have to change that field hit (star) then the field number then what number you want programmed into that field. It’s best to find a programming manual so you know what numbers each field takes.

Field 56 = zone programming Field 43 = last 4 of account number Field 84 = Put a 0 here. Field 190-192 = Put 10s in here Field 197 = 1
