KC868-V16 and 6-terminal PIR Wiring - tasman - 09-18-2025
Hello
I am looking for some help with wiring my PIRs to the KC868-A16 as I am not getting any reading when motion is detected.
My PIRs have 6 terminals:
1. +12V
2. -12V
3. ALM
4. ALM
5. TAMPER
6. TAMPER
Power is supplied successfully via the +12V terminal. The PIR was wired to the old board with one of the ALM terminals (left) and a TAMPER terminal.
I have attempted to wire to a digital input on the KC868 and GND. On the PIR I tried the ALM and TAMPER terminals which did not work. And I also tried ALM (left) and ALM (right) terminals which also didn't work. I also read I needed to jumper the TAMPER terminals together but that did not work either.
If I short the blue and yellow wires connected to the digital input and GND I do get a reading, therefore the issue is on the PIR side.
Has anyone successfully wired a PIR like this?
Thanks for your help in advance.

you should use multi meter to test your PIR output signal, whether is dry contact. maybe it's a voltage output.

I found a solution to the issue for this PIR, which is a Pyronix KX15DT. Here is a wiring diagram.
Make sure you remove any jumpers in the highlighted area.
