Question 1

What color coding indicates a sprinkler head rated for high-temperature service (286°F / 141°C)?

Accepted Answer

Purple

Answer

Purple-coded sprinkler heads are rated for high-temperature service at 286°F (141°C), used in areas with elevated ambient temperatures.

Question 2

What is the role of a 'pressure reducing valve' (PRV) in a high-rise building standpipe system?

Accepted Answer

It limits outlet pressure to prevent damage to hose lines and fittings on lower floors

Answer

PRVs limit the pressure at standpipe outlets on lower floors where static pressure would otherwise be too high for fire hose use.

Question 3

Which NFPA standard governs the installation of fire alarm systems in buildings?

Accepted Answer

NFPA 72

Answer

NFPA 72, the National Fire Alarm and Signaling Code, governs the installation, testing, and maintenance of fire alarm and signaling systems.

Question 4

A Fireguard discovers that a sprinkler head in a storage room has been painted over. What is the correct action?

Accepted Answer

Report it as a deficiency and arrange for replacement since paint can prevent activation

Answer

Paint on a sprinkler head can prevent the heat-sensitive element from activating, making the head non-functional and a fire code violation requiring immediate replacement.

Question 5

In a pre-action sprinkler system, what TWO events must occur before water is discharged?

Accepted Answer

A detection device activates AND a sprinkler head fuses open

Answer

Pre-action systems require both a detection device (smoke or heat detector) to activate AND a sprinkler head to fuse open, providing double confirmation before discharging water.
