ch11 controlling building systems

Question 1

the most common conveyance systems that firefighters must control during structure fires are?

Answer 1

escelators and elevators

Question 2

blank shafts can become conduits for spreading fire, heat, and smoke throughout the building

Answer 2

elevator

Question 3

According to ASME A17.1, safety code for elevators, all modern passenger elevators must be equipped with what is called blank operation

Answer 3

Phase 1

Question 4

because blank can be actuated by products of combustion generated early in the growth stage of a fire and do not have to wait for a specific level of heat to be produced, they can initiate an alarm much more quickly than most heat detector systems

Answer 4

smoke detectors

Question 5

What are the two types of smoke detectors?

Answer 5

ionization, photoelectric

Question 6

Most photoelectric smoke detectors are of the blank type?

Answer 6

beam application

Question 7

A blank smoke detector used a tiny radioactive beta source(usually americium) to ionize air molecules as they enter a chamber within the detector

Answer 7

ionization smoke detector

Question 8

fixed temperature thermostats usually operate by two means what are they?

Answer 8

they either have a bimetallic contact that bends in response to heat, or they have a fusible element that melts and allows the switch to close

Question 9

the bimetallic switch usually activate at blank degrees in living spaces and blank degrees in attics

Answer 9

135, 200

Question 10

rate of rise thermostats activate at rises of blank degrees in one minute

Answer 10

12 F

Question 11

blank are among the most sensitive fire detection systems

Answer 11

flame detectors aka light detectors

Question 12

blank detectors are designed to require the flickering motion of a flame to initiate an alarm

Answer 12

Infrared

Question 13

carbon dioxide extinguishing systems are most often installed to protect blank and blank?

Answer 13

electrical systems, and processes that involve flammable liquids

Question 14

Answer 14

4 percent in air

Question 15

the toxic level of halon 1301

Answer 15

10 percent in air

Question 16

This is the agent most often used to protect computer rooms

Answer 16

halon 1301

Question 17
