Additional cabinets allow for modular expansion of the Previdia fire control panel, easily adapting to different wiring and space requirements. Each cabinet comes complete with a front door, CAN drive bar for connecting functional modules, and shelves for housing batteries. On the front panel are two housings for FPM modules, useful for advanced functions; in the absence of specific requirements, FPMNUL blind modules can be used. A practical and scalable solution for growing installations or those with complex configurations.
