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.

Calculate Luminance

A typical 60-watt standard frosted incandescent bulb outputs 890 lumens for an efficacy ratio of about 15 lumens per watt. As an A19, its shape is spherical. What is the its calculated luminance? A. 25,115 cd/in² B. 25.115 cd/ft² C. 25,115 cd/m² D. Indeterminate, missing variable. Answer If 1 candela (cd) = 4 ∏ lumens (lm), 890 x 1cd/4∏ = 71 cd, A19 = 19/8 = 2.375 in or 60mm diameter (= 30mm radius), L = intensity / projected area, 71 cd / ∏ r² = 71/ 3.14 x (.03m)² = 25,115 cd/m² ARE 4.0 exam prep: BS
