CET Fire Service & Emergency Operations 2 — Questions and Answers
Question 1: When firefighters activate Phase I Emergency Recall using the key switch, elevators should return to the designated level within how many seconds for a travel time not exceeding 60 seconds?
- 30 seconds
- 60 seconds (Correct answer)
- 90 seconds
- 120 seconds
Correct answer: 60 seconds
ASME A17.1 requires elevators to return to the designated level within 60 seconds when travel time does not exceed 60 seconds.
Question 2: During Phase II firefighters' service, what happens when a firefighter holds the door open button continuously?
- Doors close immediately
- Doors remain open as long as the button is held (Correct answer)
- Doors open then close after 5 seconds
- The elevator returns to the lobby
Correct answer: Doors remain open as long as the button is held
In Phase II, continuously holding the door open button keeps the doors open, giving firefighters control over door operation.
Question 3: Which ASME A17.1 rule governs the requirement for firefighters' emergency operation (Phase I and Phase II)?
- Rule 2.26.2 (Correct answer)
- Rule 2.27.3
- Rule 2.26.1.2
- Rule 3.26.3
Correct answer: Rule 2.26.2
ASME A17.1 Rule 2.26.2 establishes requirements for firefighters' emergency operation including Phase I recall and Phase II in-car service.
Question 4: A smoke detector that initiates Phase I recall is located in the elevator lobby on the third floor. After recalling all elevators to the main floor, which floor's detector caused the recall?
- All detectors caused the recall simultaneously
- The detector at the designated level
- The third-floor lobby detector (Correct answer)
- Only the machine room detector
Correct answer: The third-floor lobby detector
Any lobby smoke detector activation initiates Phase I recall; the third-floor detector in this scenario triggered the event.
Question 5: What is the purpose of the 'independent service' mode on an elevator in relation to emergency operations?
- It bypasses all safety devices
- It removes the elevator from normal group dispatching for single-car manual control (Correct answer)
- It activates Phase I recall automatically
- It enables the elevator to run at reduced speed only
Correct answer: It removes the elevator from normal group dispatching for single-car manual control
Independent service removes the car from automatic group dispatching so it can be operated manually, but it is not an emergency mode like Phase II.
Question 6: During an active Phase I recall, if a car is traveling upward when the recall signal is received, it must:
- Continue to the next floor up, then reverse to the designated level (Correct answer)
- Stop immediately and remain stationary
- Reverse direction immediately without stopping
- Proceed to the top floor then descend to the designated level
Correct answer: Continue to the next floor up, then reverse to the designated level
A car traveling upward during Phase I recall must proceed to the next available floor, stop, then travel non-stop to the designated level.
Question 7: Which condition would cause a Phase I recall elevator to bypass the designated main floor and proceed to an alternate designated level?
- Power failure on the main floor circuit
- Smoke detected in the lobby of the main designated level (Correct answer)
- The key switch is in the 'bypass' position
- More than three cars are already at the main floor
Correct answer: Smoke detected in the lobby of the main designated level
If a smoke detector activates in the lobby of the designated main level, elevators must divert to an alternate designated level to avoid sending firefighters into a smoke-filled lobby.
