Which device is activated when the sprinkler system operates to notify occupants?

• A. Water Closet
• B. Listed or Labeled
• C. Sprinkler Positioning
• D. Alarm Device

Answer: (D)

When a sprinkler system operates, occupant notification is provided by the alarm device. As water flows from the activated sprinkler head, a flow switch or alarm device detects the movement and sends a signal to the building’s fire alarm system. The alarm panel then energizes the occupant notification devices—audible horns or bells and visual strobe lights—so people are alerted quickly. The other terms aren’t related to notifying occupants: a water closet is just a plumbing fixture, listed or labeled refers to certification, and sprinkler positioning deals with where sprinklers are located rather than signaling. The alarm device is the mechanism that ensures occupants are warned when sprinklers discharge.
