Question 1

Which type of smoke detector is most effective at detecting slow, smoldering fires?

Question 2

A wet pipe sprinkler system differs from a dry pipe system primarily because:

Accepted Answer

Wet pipe pipes are filled with pressurized water at all times

Answer

In a wet pipe sprinkler system, the pipes are constantly filled with pressurized water, allowing immediate discharge when a sprinkler head fuses.

What is the primary purpose of a fire alarm control panel (FACP)?

Accepted Answer

To monitor initiating devices and control notification appliances

Answer

The FACP monitors all initiating devices such as detectors and pull stations, and controls notification appliances like horns and strobes.

Question 4

In a pre-action sprinkler system, water enters the pipes when:

Accepted Answer

A detection device activates AND a sprinkler head fuses

Answer

Pre-action systems require both a detection event and a fused sprinkler head before water discharges, providing double confirmation to prevent accidental discharge.
