Yes, connect the sensor to any Comfort main board or Slave input (but not to LEM Input)
Program the zone is Null Zone Type
You can use the action get Analog Input to read the value from 0 to 255 corresponding to 0 to 3.3 V
In Zone Settings set the Zone type to No Zone Type or blank (at the top of the zone types list)
I forgot to say the zone shunts must be set to Double End of Line Resistors ie Away from the terminal blocks.
thanks, i got what u meant
but i want to clarify one thing
the case that i have, the Lux sensor output is active , means it produce 0-3V according to lux state.
i measure the zone and i found it produce 3V it self, My Q is? could i connect my sensor 3V output to the zone terminal ?
it's vantage , i don't have the type yet, i will post it once i got it , it is at site with one of our engineer , we didn't starup the system yet.
one more question, the wiring of lux output voltage, LUXcom(-ve) in to Zone com and (+ve) at the other ?
