Sensor inputs

[BaconRanch]

Hello,

I am trying trying to wire in a 3 wire, 12V pir motion detector.  

I have a brown wire to constant 12v source

I have a red wire ( trigger ) going to terminal for sensor #1

And I have the blue ground going to body and to ground terminal right next to terminal #1 as per legend on metal cover .

When I short ground terminal and terminal #1 I get a response but the pir is not working as expected.  Have tried other pir devices with no luck.

What is my problem here, has to be something very easy and I just can't get there because I don't know yet how to fine tune time, distance and LUX on the pir.

Picture of wiring at terminal attached .    

By the way, check out my project at YouTube video

you can use multi meter to test your PIR sensor whether can output dry contact signal when it triggered.
usually PIR sensor connect with DC12v power supply, it will have 3 wires: COMMON, NO(normal open),NC(normal close). find out correct wires connect with Server16's digital input ports.
