paradox sp5500

[proguard <proguardsec@xxxxxxxxx>]

While being a long time away from Paradox panels (from the era of
Esprit and Spectra 14XX) now returning trying to understand SP series.
I define zone 12 witch is on zx8 expander as 36 (entry delay 1 (full
arm)/instant) but the panel does not recognize it at all. The panel is
SP5500 v3.8 Any idea why that? Do i have to programm something else
around?
Also where is located the address for enabling panic buttons on the
keypad?
And for last how we can arm in instant stay mode if i can't programm
the entry/exit zones as 36?
(entry delay 1 (full arm)/instant)

Thanks in advance!
