Additional cabinets allow modular expansion of the Previdia fire control panel, easily adapting to different wiring and space requirements. Each cabinet comes complete with a frontplate, CAN DRIVE bar for connecting functional modules, and housing for batteries. The front panel includes two housings for FPM modules, useful for advanced functions; if no specific requirements are needed, FPMNUL blank modules can be used. A practical, scalable solution for growing installations or complex configurations.
