B : Rated-4 since that is the highest rating received

C : Rated-4 since electrical is more important than mechanical and architectural

D : Depends on the Rating scored in telecommunications

B :

Yes, if the data center is a potential target or the building is located within the vicinity of (close by) a potential target.

C : No, blast protection is not a requirement of ANSI/TIA-942.

D : Yes, blast protection is a requirement of ANSI/TIA-942.

Answer: B

Question 5

The pipes of a VESDA smoke detection system are installed at the air intake of the air conditioner inside the computer room. Is this a good practice from an early smoke detection point of view?

Options :

A : It depends on the type of gas-based fire suppression which will be installed.

B : Yes, as this reduces the amount of piping to be installed in the data center, as all air will go through the air conditioner.

C : No, the piping should be installed at the air exhaust of the air conditioner, as there can also be a fire inside the air conditioner itself.

D : No, it will give a longer reaction time for the smoke detection system and there might also be bypass airflow.
