Low Pressure Dry Pipe and Pre-action Systems
In accordance with the UL® Listing, Spears® FlameGuard® CPVC Fire Sprinkler
Products may be used in Low Pressure Dry Pipe and Pre-action System
applications in Light Hazard and Residential occupancies in accordance with
NFPA 13, 13D and 13R when subject to the following additional limitations:
A CPVC Low Pressure Dry Pipe or Pre-action System is a piping system
intended for use where piping could be subjected to freezing temperatures
and
water filled pipe cannot be utilized. The minimum rated temperature is -20°
F
(-29° C). Low Pressure Dry Pipe systems contain compressed air or nitrogen
(gas) having an internal gage pressure of not more than 15 psig (105 kPa).
These specially designed systems require separate control valve mechanisms
for this application (supplied by others) that activate to release water
into the dry
piping section and to the sprinkler heads. The water-filled portion of the
system
control device must be in an area protected from freezing. It is the
installer’s
responsibility to be sure the system is installed in accordance with the
limitations
of this manual and specifications of a Dry Pipe or Pre-action Fire Sprinkler
System design Engineer for proper control devices, pipe sizing, and other
important design and maintenance criteria applicable to each project. CPVC
dry
systems must be designed with the following maximum water delivery time
delay.

I think Tyco has a CPVC listed for use in dry systems?

Brian,
Don't assume that because you have a wood framed building that you must
sprinkler the attic. Check with the engineer of record to see if this
system is supposed to be a 13 or 13R. Secondly you can't run over an
ordinary hazard room in a light hazard occupancy with cpvc unless the room
is 400 ft or less. And lastly CPVC is not listed for a dry system and you
can definitely not use it. A read of the blazemaster install and
specification manual is highly recommended.

Subject: CPVC Applications
I'm doing a daycare facility and was leaning towards using BlazeMaster
CPVC but have a quick question. I know that it is listed and approved for
light hazard areas which is 90% of the project, what do you do for the
other 10%? Do I need to run steel for the Kitchen, Janitor's Closet, and
small Storage closet? Also, since this is a wood framed building I need to
sprinkle the Attic but since it cannot be used for storage it is light
hazard as well, any reason I can't use CPVC for the dry system as well?
