Title: Identify sprinkler system applications and components.
Course: Firefighting II (15152-II) > Section: Examining Fire Detection, Alarm, and Suppression Systems

Identification should include the following:

- Wet-pipe system—an alarm-check valve or backflow-prevention valve, a pressure gauge, and an electronic alarm
- Dry-pipe system—an air-pressure gauge located above a clapper and a water-pressure gauge below a clapper
- Pre-action system—a deluge-type valve, fire-detection devices, and closed sprinklers
- Deluge system—open sprinkler heads with a deluge valve
- Residential system—fast-response sprinklers tied into wet or dry systems, air- or water-pressure gauges, a flow detector, and a system drain

Process/Skill Questions:

- Where might dry-pipe systems be found?
- What are the benefits of using a deluge system?
- What are closed sprinklers, and how do they operate?
