Stopping the fire inside the tray is the most effective way to prevent broader system impacts. Direct Low Pressure (DLP) clean agent systems offer a practical solution for detecting and suppressing fires inside cable trays. A heat-sensitive detection tube runs along the tray. What Happened: On 6 January 2013, a fire erupted in the Huidong Constellation Building (Jinan, China). The resulting barrier retards the transmission of smoke, fire, and toxic gases from spreading between adjacent rooms and floors for the rated time period. Where cables pass through shafts, walls, slabs, or enter electrical panels or cabinets, openings shall be tightly sealed. FireResistant Solutions provides cable tray covering and fire-protection systems designed to safeguard electrical and data infrastructure in commercial and multifamily buildings.
