Its panel specific, in the Galaxy range I'm sure its five digits. There is
a seed number put into the panel (usually 1-255), and the algorithm is run
from that. I haven't seen any programs around that emulate it though.

When our burglar alarm goes off, it generates a 4 digit code
on the panel, which in order to reset it, one reads out to
the monitoring centre - they respond with another 4 digit
code which one types into the panel, and it allows you to reset
it.

These codes are obviously algorithmically related. How? I've never had
enough samples to work it out (and usually can't be bothered to write
them down when a spider in a PIR has awoken us at 2AM).

And are the codes common to all panels, or manufacturer specific?
