        I have two extra of these, is there a way to reset the master Installer
Code? Or is the master password somehow BIOS locked? I don't want to
throw these away if I don't have to, but they are useless of course if
they can't be unlocked! Any help appreciated. PS *,# upon power up
then entering a new master code doesn't seem to work on either panel. I
know for sure one came out of a Monitronics system,the other has
identical numbers on it and the same behavior).....

I've never come across a Monitronics that was locked..never. The main
problem is it can only report to them, you can't change the dialer number.
But you could still use it locally...or you could probably change the chip
and have a fully usable V15P


Try *# on power up, it should display 20, then do a #20 to display the
existing code, then *20 to change the installer code.

Considering the way the panel firmware is written, it's likely that
only the sub-routine for editing the dialer number has been blocked.
Thus, with a chip burner someone could easily alter the number. The
panel would then be locked onto whatever new dialer number you
assign, effectively beating Monitronics at their own sleazy game.

Hmm. Maybe Monitronics will start filing Brinks-style lawsuits. :^)

This is the realm of expanding misinformation. Talking to different folks
give you different answers. Getting the installer code out of Monitronics
can be a problem. There is a policy I am told that says disclosing the
installer code is only done at the expense of wiping all the panel
information. Someone else here might know more about that policy, but is
prone to not telling much about anything in a truthful fashion.
>you can't change the dialer number.
If you have the installer code I am told you can change the dialer number.
As a practical matter not being able to download the panel yourself is one
problem, but knowing that ONLY someone else can download it and might, even
accidentally, should cause anyone some concern.

I dunno. I can only speak from my experience from having worked on about
10-15 this year and none were locked although I could not change the dialer
number - so ended up swapping the board out.
