The building in which the computer room is housed is required to have a sprinkler system. The building is therefore equipped with a wet pipe system.

What action, if any, should you recommend for the computer room?

AMaintain the current wet pipe system.

BReplace the wet pipe system with a deluge system.

CReplace the wet pipe system with a dry pipe system.

DReplace the wet pipe system with a pre-action system.

Show Suggested Answer

Suggested Answer: D

In computer rooms, replacing a wet pipe system with a pre-action system is advisable. Pre-action systems provide additional protection by requiring two triggers (e.g., heat and smoke) before water is released, minimizing the risk of accidental discharge and water damage, which is crucial for safeguarding sensitive IT equipment.

Detailed Explanation:

Wet pipe systems contain water in the pipes at all times, which poses a higher risk of accidental discharge. Pre-action systems, however, only fill the pipes with water upon detection of a fire, reducing the risk of water-related damage due to leaks or malfunctions. This approach is considered best practice for environments housing sensitive electronic equipment.

EPI Data Center Specialist References:

EPI advises using pre-action fire suppression in data centers to reduce risks associated with accidental water release, providing a safer and more controlled fire response that better protects critical infrastructure.

I practiced a question like this, and I feel like replacing it with a dry pipe system could be safer for the equipment, but I'm not completely confident.

I'm not entirely sure, but I remember something about wet pipe systems being standard unless there's a specific risk. Should we just maintain it?

I think we might need to consider the risks of water damage in the computer room, so maybe a pre-action system could be better?

I'm confident I can solve this. The wet pipe system is not ideal for a computer room, as water damage could be catastrophic. I'll recommend replacing it with a deluge or pre-action system.

Okay, I think I know the answer to this. The computer room likely requires a more specialized system to protect the sensitive electronic equipment. I'll recommend the dry pipe or pre-action system.

Hmm, I'm a bit unsure about the differences between these types of sprinkler systems. I'll need to review my notes to refresh my memory on the key characteristics of each one.

This seems like a straightforward question about fire suppression systems. I'll need to carefully consider the pros and cons of each option to determine the best recommendation.

I agree with Franchesca, a deluge system would be more effective in case of a fire.

I'm not too sure about this one. Wet pipe systems are pretty standard, but a computer room might be a special case. Maybe a pre-action system would be the way to go?
