Question: For sudden surges in pressure above the cab, what is used as a "brake"?
Answer: a diaphragm or a piston

Question: How does it enable the cab to go down by it's own weight?

Answer: upright or sideways on the cab wall

Question: Where is the elevator motor found?
Answer: at the top of the shaft or beside the bottom of the shaft

Question: Moving the helve forward causes the cab to do what?
Answer: to rise

Question: The more pressure applied to the handle caused what?
Answer: the faster the elevator would move

Question: Why was the handle considered a "dead man switch"?
Answer: if the operator let go of the handle, it would return to its upright position, causing the elevator cab to stop

Question: Eventually safety locks were used to guarantee what?
Answer: that the inner and outer doors were closed before the elevator was allowed to move

Question: What function does a "destination operating panel" feature?
Answer: a passenger registers their floor calls before entering the car

Question: What is another benefit of a "destination operating panel"?
Answer: the computer distributes adjacent stops to different cars in the bank

Question: What is one benefit of a "destination operating panel"
Answer: travel time is reduced as the elevator makes fewer stops for individual passengers

Question: What is the downside to a :destination operating panel"?
Answer: passenger waiting times may be longer as they will not necessarily be allocated the next car to depart

Question: What is one example of a limitation on the system? 
Answer: the system is subject to gaming

Question: What is generally unable to support variations in the number of people for a particular destination?
Answer: The dispatching algorithm

Question: For what reason do people repeatedly push the up/down buttons on a panel?
Answer: people believe this to be an effective way to hurry elevators

Question: Why is this a bad practice?
Answer: this will make the computer think multiple people are waiting and will allocate empty cars to serve this one person

Question: What is one way to implement destination control?
Answer: every user gets an RFID card to identify himself

Question: How does this help the system?
Answer: the system knows every user call and can cancel the first call if the passenger decides to travel to another destination to prevent empty calls

Question: Newer systems know where and how many people are at a location for what reasons?
Answer: either for the purposes of evacuating the building or for security reasons

Question: What is another name for up-peak mode?

Answer: when they reach a pre-determined passenger load, or when they have had their doors opened for a certain period of time

Question: Why is a "this car leaving next" sign used?
Answer: to encourage passengers to make maximum use of the available elevator system capacity

Question: How is the special sercice mode enabled?
Answer: by a key switch either inside the elevator itself or on a centralized control panel in the lobby

Question: What is the impact on an elevator set to independant service mode?
Answer: it will no longer respond to hall calls

Question: At what times is Independant service best utilized?
Answer: when transporting large goods or moving groups of people between certain floors

Question: During independant service mode how is a single cab in a hall kept from being used?
Answer: the hall buttons are disabled

Question: Who is authorized to provide inspection and/or maintenance of the elevator?
Answer: qualified elevator mechanics

Question: What is the purpose of the Inspection service? 
Answer: to provide access to the hoistway and car top for inspection and maintenance

Question: What action initiates it's activation?
Answer: a key switch on the car operating panel usually labeled 'Inspection', 'Car Top', 'Access Enable' or 'HWENAB

Question: WWhat's the first thing to happen when the switch is activated?
Answer: the elevator will come to a stop if moving

Question: Once activatated, what is the only way to deactivate it?
Answer: The elevator can now only be moved by the corresponding 'Access' key switches

Question: What initiates Phase one mode?
Answer: a corresponding smoke sensor or heat sensor in the building

Question: What happens when an elevator goes into Phase one mode?
Answer: The elevator will wait an amount of time, then proceed to go into nudging mode to tell everyone the elevator is leaving the floor

Question: Where does the elevator go from there?
Answer: the elevator will go to the fire-recall floor

Question: How is the elevator enabled for service after the incident?
Answer: The only way to return the elevator to normal service is to switch it to bypass after the alarms have reset

Question: What happens if the mode is activated on the fire-recall floor?
Answer: the elevator will have an alternate floor to recall to
