Answer 5

NFPA 72

Question 6

____ specifies requirements for flame-detection alarm systems or radiant energy-sensing systems.

Answer 6

NFPA 101

Question 7

3 types of flame detectors

Answer 7

optical detectors, UV detectors, infrared detectors

Question 8

This detector aims a light beam into the room or space. When smoke blocks the beam, it sets off an alarm. These are best for heavy smoke fires.

Answer 8

photoelectric detector

Question 9

This detector reacts to an increase in temperature within a space. Because rising temperatures indicate flames, this alarm may be too late to stop a fire.

Answer 9

rise of temperature detector

Question 10

This detector senses ultraviolet or infrared light from flames. Like the rise in temperature detectors, flames might be detected too late to stop a fire.

Answer 10

flame detector

Question 11

These combine fire suppression and smoke suppression within building components, including doors, windows, and HVAC systems.

Answer 11

fire-resistant barriers

Question 12
