Often I'm asked, "can the EC's install 25 volt and 70 volt wire in the same conduit for emergency voice evacuation speakers in a fire system" . While I understand as long as it's power limited, you can. I'd like to ask the group, why you would want to do this, and have you experienced any problems from it?

Kind regards.
