KC868-A16 board - wired security system

[admin]

1. how much voltage would the circuits for Door Magnet 1 and Door Magnet 2 get?

-->usually door sensor output two wire, dry contact, not need power supply. just connect to digital input ports and GND is ok.

2. can I do this with the 12 v and 24 v power supplies?

-->why not use one DC24V power supply? KC868-A16 support DC 12-24V power supply.

3. would Door Magnet 3 and Door Magnet 4 work?

--> "Door Magnet" is a sensor? if YES, can't connect to OUTPUT port, you should connect with digital input ports, as same as "Door Magnet1" and "Door Magnet2"

Thanks share your 3D files.
