I noticed that when I use ADC to arm the system in Armed Away mode it actually switches to Armed Stay mode immediately after. Any idea what’s going on?
This would be a result of “Auto-Stay” meaning the panel will revert to Stay mode if no entry/exit doors are tripped during the Away arming countdown.
On a Vista panel this would be found in installer programming under *84. Set it to 0 to disable.
Thanks for the info!
