Sprinkler system types

A large warehouse facility in Oregon stores paper products. Which of the following fire sprinkler systems should be installed?
A. Pre-action system, B. Wet pipe system
C. Deluge system, D. Dry pipe system


Answer is A.
Pre-action systems would be best to avoid an unintended discharge of water and damage to the paper stock. A fire detection event (heat/fire detector activation) must precede the release of water into the system's piping, preventing accidental release in the case of a leak.
