Which type of sprinkler was described as standard response pendent?

• A. Quick Response Pendent Sprinklers
• B. Deluge Pendent Sprinklers
• C. Standard Response Pendent Sprinklers
• D. Wet Alarm Pendent Sprinklers

Answer: (C)

Sprinkler heads are categorized by how quickly they respond to heat and by how they’re mounted. A pendent head hangs downward from the piping, delivering water below. The term “standard response” refers to the conventional heat-sensitive element design used in most installations, with a moderate response time—not as fast as quick response but widely used for general applications. So a pendent sprinkler described as standard response combines the downward mounting with the standard, conventional response characteristics.

In contrast, quick response pendents have a faster-activating element, deluge pendents are used in deluge systems where all heads discharge water, and wet alarm pendents include an integrated alarm switch that triggers when water enters the head. That’s why the description matching “standard response pendent” is the correct choice.
