Smoke evac for retrofit

Hello All

Have a 6 story building with old JC smoke control panel (bunch of HOA switches for fans and dampers) it must be 100 wires chris crossing in the box , now the FM wants the new Notifer panel to run the smoke system. I believe we need to get head company involved , but want to know if there is any material to help me out there. Think I many need to mount new modules and control relay at each damper and fan and have LED make up a new control panel.

Any help appreciated
