Discuss Exin CDCS Exam Topic 2 Question 27

Smoke sensors must be installed in the computer room. What is the minimum density?

A1 per 5 m

B1 per 10 m

C1 per 25 m

D1 per 40 m

Suggested Answer: C

NFPA 75 (Standard for IT Equipment Protection) and NFPA 72 (Fire Alarm Code) recommend installing at least one smoke detector per 250 ft (25 m) in IT rooms. This ensures early detection in high-value environments.

A and B are far too dense, exceeding NFPA minimums.

D is too sparse and would not meet early detection requirements.

Therefore, the correct standard density is 1 per 25 m.

D) 1 per 40 m? That's risky! A) is the way to go.

But what if there's a fire? A) is better!

I vaguely recall that the standard is usually stricter for sensitive areas like computer rooms, so it might be 1 per 5 m.

I’m a bit confused about the minimum density. I thought it was 1 per 25 m, but that seems too sparse for a computer room.

Barbra 6 months ago

I practiced a similar question last week, and I believe the answer was 1 per 10 m, but I could be mixing it up with fire alarms.

Cory 6 months ago

I think I remember something about smoke sensor density, but I'm not entirely sure if it's 1 per 10 m or 1 per 5 m.
