Constructed from intumescent material that expands under heat to seal gaps and slow fire spread, the hood creates a barrier between the void above the ceiling and the room below.\u003c\/p\u003e\n\u003cp\u003eInstalled in commercial, industrial and residential ceiling voids where recessed luminaires are fitted into fire-rated ceilings, the hood maintains the ceiling's structural fire rating by containing combustion within the void for up to 60 minutes. The 220mm minimum void requirement accommodates the hood depth plus clearance above the recessed fitting. Internal support rods and bulldog-style clips hold the hood in position over the fitting without requiring separate fixing points to the ceiling structure.\u003c\/p\u003e\n\u003cp\u003eThe intumescent material is lightweight and flexible before exposure to heat, making the hood easier to handle during installation than rigid alternatives. The 620mm external dimension accommodates modular recessed fittings with standard 600mm mounting centres, sitting flush around the fitting perimeter. The hood does not provide acoustic attenuation, only fire protection.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e620mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e200mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e620mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Void\u003c\/td\u003e\n\u003ctd\u003e220mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eIntumescent material\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5 Year Guarantee\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/datasheet-FR600.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat fittings is this fire hood compatible with?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe FR600 is designed for Knightsbridge MRB, MRD and MRE modular recessed luminaires with 600mm mounting centres.
