We are a special hazards fire suppression contractor in Minneapolis. I have a customer that has Omniguard Flame Detectors, #752-00402311211, Model # 9321-006. They are installed in a LP gas tank farm (class 1, Div. 2). The owner wants to remove them and is asking what kind of wire was used to connect them. Any idea what kind and/or type wire may have been used to connect them to a panel?
Thank you
Ken
