What are the two primary types of sprinkler systems?

1. Dry and wet pipe

2. Deluge and pre-action

3. Foam and water mist

4. Residential and industrial

The correct answer is: Dry and wet pipe

The primary types of sprinkler systems are categorized based on their methods of water delivery and the conditions under which they operate. Wet pipe systems are filled with water and discharge it immediately when a sprinkler is activated, providing prompt fire suppression. This type of system is commonly used in areas where the risk of freezing is low, making it effective and reliable for standard fire protection needs. On the other hand, dry pipe systems are filled with pressurized air or nitrogen instead of water. When a sprinkler head opens, the air pressure drops, causing a valve to release water from a reservoir. This system is essential in environments where there is a risk of freezing, as it prevents water from sitting in the pipes and potentially freezing before deployment. Thus, both wet and dry pipe systems serve specific functions based on environmental conditions and the desired response time for fire control. Recognizing these fundamental types is critical for fire safety professionals as they determine appropriate system design and installation based on the specific needs of the building or area being protected. The other options, while related to fire protection systems, represent more specialized or specific types of sprinkler systems rather than the primary classifications.
