Question 1

A pre-action sprinkler system requires which condition before water is discharged?

Accepted Answer

A detection event AND sprinkler head activation

Answer

Pre-action systems require both a detection event (from a smoke or heat detector) and individual sprinkler head activation, providing two steps of confirmation before water flows.

Question 2

Which type of fire suppression agent is most appropriate for protecting a server room with sensitive electronic equipment?

Accepted Answer

Clean agent (e.g., FM-200 or Novec 1230)

Answer

Clean agents such as FM-200 or Novec 1230 suppress fire without leaving residue and are electrically non-conductive, making them ideal for protecting electronic equipment.

Question 3

What is the primary purpose of a fire department connection (FDC) on a sprinkler system?

Accepted Answer

To allow firefighters to boost water pressure to the system

Answer

The FDC allows fire department pumper trucks to supplement or restore water supply and pressure to the building's sprinkler system during firefighting operations.

Question 4

Under NFPA 13, what is the minimum clearance required between the top of storage and sprinkler deflectors?

Accepted Answer

18 inches

Answer

NFPA 13 requires a minimum 18-inch clearance between the top of storage and sprinkler deflectors to ensure proper water distribution when sprinklers activate.

Question 5

A deluge sprinkler system differs from a standard wet-pipe system because it:

Accepted Answer

Has open sprinkler heads that all discharge simultaneously when triggered

Answer

Deluge systems have open (non-fusible) sprinkler heads, and when the deluge valve opens due to fire detection, water flows from all heads simultaneously across the entire zone.
