The function of sealing off cable trays on different floors

They ensure that openings in walls or floors for feeding through electrical, data, coaxial, and glass fibre cables as well as cable support constructions and electrical installation conduits can be sealed so that the fire resistance of the building element is restored. FIRSTO firestops are designed to seal multi-cable and cable tray penetrations of fire-rated walls and floors. Working in inaccessible openings is often cumbersome. Cables, cable bundles, conduits, bundles of conduits, empty pipes, cable trays and cable ladders may also pass through penetration seals in walls and floors and should be taken into consideration during all phases of design and application. The last part of our penetration seal series of articles. The main types of accessories are categorized by their function: Fittings change the path or size of the run, including Elbows (for horizontal or vertical direction changes), Tees and Crosses (for multi-directional junctions), and Reducers (to transition between different tray widths). Support. The requirements to seal openings apply wherever a wiring system passes through an element of building fabric having specific fire-resistant properties.
