Which of the following are the types of fire sprinkler systems?
1. Wet pipe
2. Pre-action
3. Dry pipe
4. Deluge
Select the correct answer using the code given below.
Explanation
Fire sprinkler systems are categorized into four primary types based on their operational mechanisms:
- Wet Pipe: The most common system; pipes are always filled with water for immediate discharge upon heat activation of a sprinkler head.
- Dry Pipe: Pipes contain pressurized air or nitrogen instead of water. Water enters the system only when a sprinkler head opens and air pressure drops, making them ideal for freezing-prone environments.
- Pre-action: Similar to dry pipe but requires a preceding detection event (like a smoke alarm) to allow water into the pipes. This provides an extra layer of protection against accidental discharge in sensitive areas like data centers.
- Deluge: Features open sprinkler heads. A separate detection system triggers a valve to release water to all heads simultaneously, used in high-hazard industrial zones.
As all four options represent recognized fire sprinkler technologies, the correct answer is 1, 2, 3, and 4.
