Hi,
Anyone help me with the replacement wiring for a swapout on my new PIR sensor. My original has only the marked terminals : A B C D E F, only 4 wires used (A-D).
Tried various combinations on the new marked T2 T1 NC C V- V+ but keeps coming up fault on keypad panel.
Had to replace original back so my alarm still works.

Hi,
Thanks for the reply. I think it is indeed what you said. How do I transfer the colours to the new one? I’ll attach pic of old and new.

Thanks very much. I’ll give it a try tomorrow. Although I fear I may have tried it.
