NOTES:
(a) The F890 (SIN G1890) Sprinklers may be used in QR-EC and EC, as applicable, Light Hazard Occupancy automatic sprinkler applications
per NFPA 13.
(b) Requirement is based on minimum flow in GPM from each sprinkler. The indicated residual pressures are based on the nominal K-factor.
(c) The F890 (SIN G1890) ECLH Sprinklers are only permitted to be used with unobstructed, smooth ceiling construction as defined by NFPA
13.
(d) Follow the requirements of NFPA 13 for spacing of the F890 (SIN G1890) ECLH Sprinklers with respect to ceiling mounted obstructions.
(e) The minimum allowable spacing between the F890 (SIN G1890 )ECLH Sprinklers, to prevent cold soldering, is 8 feet (2,4 m).
(f) The maximum permitted ceiling slope for F890 (SIN G1890) ECLH Sprinklers is a 2 inch (50,8 mm) rise over a 12 inch (304,8 mm) horizontal
run.

NOTES:
(a) The F890 (SIN G1890) ECLH Sprinklers may be used in QR-EC and EC, as applicable, Light Hazard Occupancy automatic sprinkler system
applications per FM installation standards.
(b) Requirement is based on maintaining both minimum flow and minimum pressure.
(c) The F890 (SIN G1890) ECLH Sprinklers are only permitted to be used with smooth level ceilings per FM installation standards.
(d) The minimum allowable spacing between the F890 (SIN G1890) ECLH Sprinklers, to prevent cold soldering, is 8 feet (2,4 m).
(e) The maximum permitted ceiling slope for F890 (SIN G1890) ECLH Sprinklers is a 1 inch (25,4 mm) rise over a 12 inch (304,8 mm) horizontal
run.
(f) The deflector-to-ceiling distance for the F890 (SIN G1890) ECLH Sprinklers is 1-5/8 to 4 inches (41,3 to 101,6 mm), unless the Model F705
Recessed Escutcheon is utilized.
(g) The maximum ceiling height for the F890 (SIN G1890) ECLH Sprinklers is 10 feet (3,1 m).
