Hi can anyone tell me if you can use a wired bell box on the powermaster 10 or does it have to be wireless I know you can add a module on the 30 but can't seem to find one for the 10. Just did not know if they was a way round it. Thanks

You'd need an external power supply and use the EOL zone and output bit like a Powermax, been a while since I worked on one tho.

They don't take the expander module from the 30, just a relay board.
