Description
The Model G4XLO QREC is a cULus Listed quick-response extended coverage concealed pendent sprinkler with an 11.2 (160 metric) K-factor for use in light and ordinary hazard occupancies. The Model G4XLO QREC sprinkler utilizes a sensitive 165°F (74°C) soldered alloy fusible element and a 135°F (57°C) flat cover plate. Maximum coverage area per sprinkler is 400 ft2 (37.2 m2).
Systems using extended coverage sprinklers use fewer sprinklers and less piping which can result in lower installation cost. Additionally, the larger 11.2 (160 metric) K-factor of the GXLO QREC results in lower discharge pressures when compared to smaller K-factor sprinklers.
