DSC brain problem

[Matt Ion]

My sister's house came with a DSC PC1500 (or maybe PC1550, I don't
recall exactly) system, and I finally got around to tracking down a
manual and trying to set it up for her... but no luck. The reset
process seemed to work properly, on some tries... on others it had no
effect. The master code was reset to default, but the installer code
appears to be locked out.

After several different reset attempts, it eventually locked up hard
with all the panel LEDs lit, and I can't clear them - even powering off
for days, it still comes up with them all lit solid.

Anyone have any suggestions on how to reset this thing back to factory?
Or is it the same as the Paradox, where locking out the installer code
can only be "undone" at the factory?

TIA...

i install DSC all day long and i suggest dont waist your time on a
PC1500 and second of all you probably zaped the eprom with the ressetable
programing on it panel is unfixable and also know that the minute a
panel has been reseted its not under warranty anymore because they know
it means troubble

a new Board PC 1555 mx is like 95 dollars and it come with one keypad
one motion amd power supply

Thanks for the tip... I've actually been considering replacing my own
PC1500 home alarm (came with the place when we bought it) with a Paradox
system (my employer's regular wholesaler handles Paradox, so I can get
it at cost); I've found their programming a LOT easier and I've been
*VERY* impressed lately with their customer service), and just
transferring this PC1500 to my sister's place Sounds like her
existing system is a paperweight now...

What's happened is you have partially defaulted the board. All the zones are
open because everything except the installer code has been defaulted back to
factory. This happens when the board is locked (you can tell when it
"clicks" when powered up with AC). If you're in Eastern Canada, I can unlock
it for you but with postage both ways, and $20 for the default process, it's
hardly worth it.....(www3.sympatico.ca/rh.campbell/unlocking_services.htm)

The 1500 is old, and can't be dialed into for upload / download purposes
(the 1550 can however), so best to simply replace it with a newer system.
You wouldn't run your business with a 286 class computer, so why run your
home security with the same vintage alarm panel, especially with alarm
panels being so inexpensive nowadays.

BTW, to my knowledge, none of the factories will unlock boards that have
been locked out. That would defeat the lockout security feature of their
boards, plus this way they get to sell another board...
