This method will work some of the time on the version 4 1550's. Most times
it will not work, and other means are called for that require special
equipment. Version 3's and lower use another much easier methodology.....
The process btw, is to power down, run a jumper from pgm 1 to the TOP pin of
the reset jumper for 4 seconds, disconnect and power back up. In a lot of
cases this does clear the lockout, but the installer code has not been
changed. Then sometimes, it will allow you to default as per factory
instructions and proceed from there. But if you connect pgm 1 to the bottom
jumper, you will destroy the board.......
Ironically, the 1550 is the most difficult of all of the DSC panels to crack
into. For those of us that do it, the above way is definately not the best
way, and is really not recommended due to the potential risk to the board
(which often won't show up until you try to connect to the central station).
So if you're going to try this yourself, be prepared to lose a board or two
at worst until you get the hang of it.....
