Quick Response,

DH56 HSW FP Recessed (See Fig. 6)
with SWC coverplate (See Fig. 7)
have ½" adjustment. The SWC cover plate is attached with
135 & 165 degree solder. In the event of a fire the rising
ambient temperature melts the solder and the cover plate is
ejected away by springs exposing the 3mm frangible glass
bulb. The use of a 3mm bulb allows quick response which
enables the sprinkler to apply water to a fire sooner than stan-
dard response sprinklers of the same temperature rating.
Model DH56 dry sprinklers are intended for use in dry and
preaction systems to protect areas subjected to freezing tem-
peratures and unheated portions inside buildings. See Fig. 1
for guidelines on using dry sprinklers in wet systems.
