During Phase II firefighters' service, if power to the elevator is lost, what should the elevator car do?
Answer: Automatically transfer to battery lowering operation to descend to the lowest landing
Battery lowering operation activates on power loss to lower the car to the lowest landing and open the doors, allowing trapped passengers to exit.
A building has 20 floors with the main lobby at floor 1. A smoke detector activates on floor 7. Under Phase I recall, where do elevators go?
Answer: Floor 1 (main designated level)
Phase I recall sends all elevators to the main designated level (floor 1 lobby) regardless of which floor's lobby detector activated.
What is the maximum time allowed for Phase I recall to be initiated after the fire alarm system sends the recall signal, per ASME A17.1?
Answer: Immediately (no delay permitted)
ASME A17.1 requires Phase I recall to initiate immediately upon receiving the fire alarm signal with no intentional time delay.
An elevator technician is testing Phase I recall. After activating the lobby key switch to 'RECALL,' one car continues to answer hall calls. What is the most likely cause?
Answer: The Phase I wiring to that car's controller is open or disconnected
If a car continues normal operation during Phase I recall, the most likely cause is a wiring fault preventing the recall signal from reaching that car's controller.
Which code defines fire-resistive construction requirements for elevator hoistways in the US that complement ASME A17.1 elevator fire service requirements?
Answer: IBC (International Building Code)
The International Building Code (IBC) specifies fire-resistive construction ratings for hoistway enclosures, which work in tandem with ASME A17.1 operational requirements.
Under ASME A17.1, what is the required action of a hydraulic elevator when Phase I recall is initiated?
Answer: Travel to the designated level and park with doors open
Hydraulic elevators must respond to Phase I recall by traveling to the designated level and parking with doors open, just like traction elevators.
A firefighter on Phase II service wants to travel from floor 5 to floor 12. After pressing the '12' button and pressing door close, the doors do not close. What should the technician check first during the post-incident inspection?
Answer: Whether the door reopening device (safety edge) was obstructed or defective
A defective or obstructed door reopening device (safety edge or light curtain) can prevent door closing during Phase II service.
