Good find on the video, Harald. I've never seen a DSC 5010 Panel defaulted that way, but that's probably because I've worked exclusively in North America. Alarm panels used in the UK and Europe, and presumably Eastern Europe, have different standards and I'm guessing that the panel in the video was made for use in Czechia, and its firmware is sightly different from our North American panels.
OP had indicated that he's using LED keypads and the video uses an Alpha Keypad, so he won't get the same feedback during the procedure. Also, the video is for resetting the panel to default values
when you have the Installer/Programming Code, and do not need to power down the system. OP has indicated he tried a power cycle with hardware short procedure, which usually is only done when the Installer/Programming code is not known.
In the OP's earlier thread (posted in Troubleshooting and Repair, as it should be), when I answered his earlier post....
i have connected zone 1 to pgm1 and powered up never get led 1 to light but program lights up but keyboard is locked
I didn't stop to consider that OP might be posting from the UK or Europe, so that's my bad.
@richard0: It would be a lot easier to help you if you tell us where you're posting from. Not all DSC Power 832 (aka PC5010) Control Panels have the same firmware and software in their programming.
Also:
Why are you defaulting your panel? Is this a new installation, or an attempt to fix a problem in an existing system?
Did your keypads work okay before you tried the default procedure? The default procedure assumes you have keypads that are working normally.
Please let me know what is going on, and I'll try to help.
