Description

The Reliable Model G4 XLO-QR ECOH Concealed sprinkler is an Extended Coverage Sprinkler for use in Ordinary Hazard Group 1 and 2 occupancies with a coverage area of up to 400 square feet (37.2 m2 ) per sprinkler. The use of ECOH 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 ECOH can eliminate the need for precise cutting of drop nipples. The Thread-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 Thread-on/Thread-off cover plate assembly.
