DSC: My programming attempts do not match the program form in the manual I have.
There are multiple versions of the "power series" panels (632, 832, 864). Some have very small programming changes from the original version, others (the CP-01 versions) have major changes in important programming areas. There are not a lot of visible differences, and both versions are sold concurrently. There are also small technical changes that were only documented in technical dispatches sent to dealers.
DSC: I defaulted my panel and now all of the zones show "open".
A lot of DSC panel installers choose to not use the End of Line Resistors (for a myriad of reasons) and instead choose to use a feature in the programming that turns off the requirement. When the panel is defaulted, this requirement is turned back on.
The specific location that has to be changed will vary by model, but will usually be in the system options sections of the program.
DSC: The power was off/I powered down the panel, and now the trouble light is on:
Nearly all DSC models require a clock reset after a loss of primary and backup battery power. The keystrokes for fixing this will vary by model, but is generally pretty easy to resolve. It's a user manual issue
