Help choosing equipment for my small project

[PaPiTo]

Hi!

Well, finally received today the board.

Flashed last firm KCS_KC868_A2_V2.2.19.bin, no problem, everithing works well.

Buyed Tuya License (waiting reception...)

But I think I must change my plan....

I will power the board with a separate PSU 12vDC, then I can`t use de D1 1 and D2 2 as alarm jump notice and alarms status, cause the alarm board works in the OUT1 and OUT2 with ground or not ground for change status, taking the ground of the alarm board.

It's possible to input +12v in D1 and D2? or only works shorting with ground? When +12v inputs on DI 1 - > alarm start (for example)

If possible, how configure the parameter Input on board?

Thanks in advance,

Best Regards
