NOTES:
(a) The K11 ECLH Sprinklers may be used in QR-EC Light Hazard Occupancy automatic sprinkler applications per NFPA 13.
(b) The K11 ECLH Sprinklers are only permitted to be used with unobstructed, smooth ceiling construction as defined by NFPA 13.
(c) Follow the requirements of NFPA 13 for spacing of the K11 ECLH Sprinklers with respect to ceiling mounted obstructions.
(d) The minimum allowable spacing between the K11 ECLH Sprinklers to prevent cold soldering is 8 feet (2,4 m).
(e) The maximum permitted ceiling slope for K11 ECLH Sprinklers is a 2 inch (50,8 mm) rise over a 12 inch (304,8 mm) horizontal run.
(f) The deflector-to-ceiling distance for the K11 ECLH Sprinklers is 1-5/8 to 12 inches (41,3 to 304,8 mm), unless the Series 4221 Recessed
Escutcheon is utilized.
