Hi, Been on before about tamper problems. I have disconnected tamper wires in my Optimax panel and put link back in assuming this isolates my PIR,s. As my tamper on my panel is still working, I presume the same applies to my Bell box as there seems to be seperate tamper wires for them on right side of panel.Any one know if this is correct? It,s a while since I installed it, forgot a bit about it.Trying to find the fault by process of elimination.
