I’m working on a pyrotronics mxl panel. I continuously get multiple in and out troubles of device multiple response and device communication error on loop 2. Are the devices that come up communication error need to be replaced? Or is it the devices that come up with device multiple response trouble need to be replaced?

May need further investigation. Are there other devices on the same wire loop as the ones with the issues? One bad device or one with an address issue could show up as several components with communication issues.
You have a wet, or a bad device. Divide & fix
