I have both the alarm board and an add-on board. I'm struggling to understand how the zones on each can be either input or output, and in each mode, what is the voltage? The simplest case of a sensor that is normally closed and goes open when the sensor is tripped is the easiest to understand.
But now comes a motion detector which I have wired with three wires: red for +12V, white for -12V, and green which returns +12V if and only if there is motion. For this I need a zone to act as a voltage input. Is that possible? Am I going to need a 12V relay to open/close a circuit? [I admit that my assumption in how this works is what led to one of my nodeMCU boards going up in smoke].
Then there is the case where I want to drive a bank of eight 5V relays. These relays switch on/off status LEDs, chimes, buzzers, open/close garage door, etc. I assume I could use the zone outputs (or OUT) to drive a relay. Correct?
