The Reliable Model G4 XLO-QR ECLH/ECOH Concealed sprinkler is an Extended Coverage Sprinkler for use in Light Hazard and Ordinary Hazard occupancies with a coverage area of up to 400 square feet (37.2 m2) per sprinkler. The use of extended coverage sprinklers can provide lower installation costs by requiring fewer sprinklers, less piping and reduced labor. The larger K-factor 11.2 (160 metric) provides for reduced pressures to achieve the required flow compared with smaller K-factor sprinklers. The G4 XLO-QR ECLH/ECOH can eliminate the need for precise cutting of drop nipples. The Push-on/Thread-off cover plate assembly provides up to 1/2” (13 mm) of adjustment to allow the cover to fit accurately against the ceiling. The fire protection system need not be shut down when adjusting or removing the Push-on/Thread-off cover plate assembly.
