🧾 Definition
Fire suppression systems detect and control fire to protect people, facilities, and sensitive equipment. The right system depends on the environment, the asset type, and the level of risk.
🔑 Key Points
- Wet pipe systems are common but may cause water damage to electronics.
- Dry pipe and pre-action systems are used where accidental discharge is a concern.
- Deluge systems are used for rapid, broad-area suppression.
- Clean-agent systems are often chosen for data centers and server rooms because they reduce water damage.
⚠️ CISSP Insight
- Physical security controls must consider both life safety and asset protection.
- The best suppression method depends on whether the environment contains electronics, flammable materials, or people.
⚔️ Key Difference / Trap
- Water-based vs clean-agent systems
- Water-based systems are effective for many facilities but may damage equipment
- Clean-agent systems are often preferred for IT environments
- Sprinklers are not always the best choice for data centers
🏗️ Example
A server room may use a clean-agent suppression system rather than a standard sprinkler system to protect equipment from both fire and water damage.

🔁 Quick Recall
- Fire suppression = protect life and assets
- Match the system to the environment
