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?

Accepted Answer

60 seconds

Answer

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?

Accepted Answer

Doors remain open as long as the button is held

Answer

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)?

Accepted Answer

Rule 2.26.2

Answer

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?

Accepted Answer

The third-floor lobby detector

Answer

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?

Accepted Answer

It removes the elevator from normal group dispatching for single-car manual control

Answer

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.
