Products Description

The Model DH80 family of sprinklers are quick response
extended coverage sidewall sprinklers for use in light hazard
applications. The Model DH80 with SWC cover plate is a
concealed sprinkler that uses Reliable's push on/thread off
sidewall cover. This sprinkler has the cup factory mounted and
is shipped with a protective cap that protects the 3mm
frangible glass bulb during shipping and post installation
finishing operations. The DH80 can be combined in the field
with the FP or F2 Escutcheon to make a recessed sprinkler.
The SWC cover plate, FP and F2 recessed escutcheons have
½" adjustment. The SWC cover plate is attached with
135-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 standard
response sprinkles of the same temperature rating.

Application

The Model DH80 is a horizontal sidewall sprinkler intended
for installation in light hazard occupancies in accordance with
NFPA 13. These sprinklers are designed to provide fire
protection in long and narrow spaces such as hallways,
corridors, decks and rooms up to 28 feet (8,5m) wide and 14
feet (4,3m) long. They are rated for 250 psi (17,2 bar) and can
be mounted between 4 and 12 inches (102 and 305mm)
down from the ceiling.
