Please join us for our June Chapter Meeting at the Mt. Tabor Brewery &
Tap Room in Portland on June 18th.Karl Wiegand, P.E. of Globe Fire
Sprinkler Corporation will be providing two educational courses with
CEUs.
Karl works in the technical education department at Globe Fire
Sprinkler Corporation where his primary duties consist of providing
training, providing technical support, and representing Globe’s
interests within the fire protection industry. Karl holds a
Professional Engineering license in the field of Fire Protection
Engineering and is a graduate of Worcester Polytechnic Institute with
a Bachelor of Science degree in Mechanical Engineering and a Master of
Science degree in Fire Protection Engineering. Over the last ten
years Karl has held positions on NFPA 15, NFPA 24, and NFPA 750.
Karl continues to represent the sprinkler industry on NFPA 16, 101,
820, and 5000 and Underwriters Laboratory’s UL199 STP.

Course Descriptions:
Concealed Space Protection - NFPA 13 requires that all combustible
spaces greater than 6 inches in height be protected by sprinklers.
However, standard spray sprinklers are not capable of developing
adequate spray patterns to provide acceptable protection for spaces
that are between 6 and 36 inches in height. For these spaces specially
listed sprinklers that provide a more horizontal spray pattern that is
capable of developing quickly are necessary. NFPA 13 acknowledges this
and requires the use of sprinklers that has been specifically listed
for combustible concealed spaces to be used in all spaces between 6
and 36 inches in height. The standard does not, however, provide any
installation requirements for these sprinklers. In order to pass their
rigorous testing requirements, these specially listed sprinklers that
are used in combustible concealed spaces need to be installed in
different configurations that typical spray sprinklers. The intent of
this presentation is to provide guidance at to what types of spaces
these sprinklers can protect and the different installation
requirements for protecting each of these types of spaces to stay
within these sprinklers’ listings.
Dry System Air Pressure: The High Road or the Low Road - Dry pipe
valves have historically been differential style valves to allow a
lower amount of system air pressure to hold back a larger amount of
water pressure in the system supply. Traditionally, though this
differential exists, dry sprinkler systems have always required a
fairly significant amount of air pressure. With new technology
developments, low pressure dry pilot actuators have allowed a lower
amount of air pressure to hold back the water pressure in the system
supply. With these developments the concept has been embraced that a
lower air pressure system is better for fire protection. The idea
being that lower air pressure in a dry pipe system will allow the air
pressure in the system to evacuate quicker which will in turn allow
the system to fill with water quicker and thus provide water to the
fire quicker. However, this is not always the case. This presentation
is intend to differentiate when and why it is more advantageous to
maintain a higher system air pressure versus the use of low air
pressure in the in the system.
