The shunt trip breakers are pretty straight forward. They will have grounded conductor wire that attaches to the neutral and either a terminal or a pigtail for the switch leg to energize the trip coil. You will have to run a hot and switch leg to the fire suppression panel. There should be a set of contacts inside the panel ( the wires are usually hanging out of the side of panel and you can mount a j- box over them) There is usually 1 NO and 1 NC contact with a common between the two. Terminate your hot to the common and the switch leg to the NO. Whenever the fire suppression system is initiated, the contacts will close and energize the coil on the shunt trip.
