How many wires do you have connected to the data bus on the M1? If you have only one set of wires connected to the M1 then the M1 should be terminated. If you have two sets of wires connected to the M1 then the M1 should not be terminated.liberty said:Right now I only have the two way setup directly on the RS 4856 Bus. I was losing my Burg 6020 devices. I just recently found a bad termination pin J3 main board (no continuity between the pins. A little wire at the top bridges the pin and that was broken. I have successfully powered off the unit and all smokes, PIR's and Burglar are normal after several power downs..
Interesting what you state about the M1XRF2H I never noticed it over 3 years having to reset 12 devices after a power is down. Thanks for that update.
