Product Description
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 m
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 Thread-on/Thread-off cov-
er 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.
