7
Wet Pipe

• May be used were piping is installed in areas
  that can be reliably maintained at a temperature
  above 40 degrees Fahrenheit

8
Dry and Pre-action

• These systems are used when piping cannot be
  maintained at a temperature of 40 degrees
  Fahrenheit or greater
• Where these systems are installed they shall be
  installed under N.F.P.A. 13 (The Standard for the
  Installation of Sprinkler Systems )

9
Upright and Pendant Sprinkler Heads

• Heads that have not been listed with specific
  positioning criteria shall be positioned so that
  the deflectors are within 1in.-4in from the
  ceiling
• Must be located 3 ft from obstructions
• Center of obstruction to the center of the head
• Where heads cannot be placed 3ft from an
  obstruction they shall be placed at either side
  of the obstruction

10
Sidewall Sprinkler Heads

• Sidewall heads shall be located so that their
  deflectors are 4in.-6in. From the ceiling
• Must be located 5 ft from obstructions
• Center of obstruction to the center of the head
• Where heads cannot be placed 5ft from an
  obstruction they shall be placed at either side
  of the obstruction

• If a sprinkler is to be located in an area with a
  temperature less than 100 degrees Fahrenheit the
  head shall be an ordinary temperature rated
  sprinkler
• If the temperature exceeds 101 degrees Fahrenheit
  then an intermediate-rated sprinkler must be used
