Question

hvac ductwork systems are often equipped with duct ____ that will deactivate fans and shut smoke dampers in an effort to limit smoke spread.

flame detectors
heat detectors
smoke detectors
carbon monoxide detectors

question 32
1 pts
an added benefit to smoke management systems in addition to reducing occupant deaths and injuries and aiding in the safety of firefighters is the reduction of property loss from smoke damage.

true
false

Explanation:

Analyze the first question

The first question asks about the device installed in HVAC ductwork systems to deactivate fans and shut smoke dampers to limit smoke spread.

• Flame detectors and heat detectors are typically installed in open spaces to detect active fires or high temperatures, not inside ducts for early smoke control.
• Carbon monoxide detectors monitor toxic gas levels for life safety but are not standard for HVAC damper control.
• Duct smoke detectors are specifically designed to sample air moving through HVAC ducts to detect smoke, triggering fan shutdown and damper closure to prevent smoke from circulating throughout a building.

Analyze the second question

The second question (labeled Question 32) is a True/False statement regarding the benefits of smoke management systems.

• The primary goals of smoke management systems are life safety (reducing occupant deaths/injuries) and assisting firefighter operations.
• An inherent secondary benefit of controlling and removing smoke is the minimization of smoke migration to unaffected areas, which directly reduces property damage and financial loss caused by smoke soot and residue. Therefore, the statement is True.

Answer:

Question 1

• flame detectors
• heat detectors
• smoke detectors (Correct answer)
• carbon monoxide detectors

Question 2

• True (Correct answer)
• False
