Combustible Attic Installations with
Specific-Application Sprinklers:
Specific Application Attic Sprinklers are designed to provide protection of
specific, light-hazard combustible and non-combustible attic spaces that
require sprinkler protection. The sprinklers must be installed in accor-
dance with Tyco Fire Products’ Technical Data Sheets TFP6-1.0 (dated
March 2001) for Specific Application Attic Sprinklers. CPVC pipe and fit-
tings CANNOT be used to install Specific Application Attic Sprinklers.
Victaulic FireLock CPVC Sprinkler System Products can be installed
within an attic space, provided that the attic space is protected with UL
Listed Tyco Fire Products Specific Application Attic Sprinklers, and the
CPVC pipe and fittings are used only to feed the wet sprinkler system
below the ceiling.
According to the guidelines found in TFP6-1.0, Victaulic FireLock CPVC
pipe must be covered by 6 inches minimum of non-combustible insula-
tion that extends 12 inches on each side of the pipe centerline (when
protected above with Specific Application Attic Sprinklers). If the pipe is
installed between the ceiling joists, and the area above is protected by
Specific Application Attic Spriklers, the joist channel must be covered or
filled with 6 inches of non-combustible insulation on top of the pipe.
NOTE:
Insulation is for fire protection purposes only; it is not intended for
freeze protection.
Multi-Purpose Systems:
Multi-purpose systems are defined as a piping system designed to serve
both domestic and fire protection needs in a residential occupancy. Vic-
taulic FireLock CPVC Sprinkler System Products are UL Listed for use in
multi-purpose systems, as defined in NFPA 13R and NFPA 13D, where
there are no provisions to prevent domestic water flow upon activation of
the sprinkler system. Design and installation of these types of systems
shall be in accordance with Chapter 6 of the 2002 edition of NFPA 13R
and NFPA 13D.
