Good day all, 

I am having an issue with an MXL system.  I had to replace the main board due to loop 2 quit working.  I was able to install the original program.  I found that there was a pull station mounted on loop 2 that was "shorted" according to the hand programmer and I replaced it after matching the address to what was missing but now I am showing to have 6 devices all in that same room offline?  They all have voltage and I have a more unique problem.  When I take the original device to the panel and mount it on the SLC with both of loop 2 address 5 the panel shows duplicate address?  The voltage to the remote building is bouncing between 19 and 22 volts, what is the amp draw supposed to be on a system ran thru 140 feet of cable on MXL?  

Any feedback would greatly help me. 

Thanks, 

David
