Study Notes

Recall Operations Overview

Recall operations are divided into two phases for elevator management during emergencies.

Phase One: Elevator Recall

Function: Recalls elevators to the main floor without stopping, making them inoperable for occupants.
Key Box Location: Found conspicuously on the main floor near elevator banks, containing keys for elevator operation.
Key System: Each banking of elevators shares the same key type; one key for each elevator and one for recall.
Activation Process:
- Use a Box key to open the metal key box.
- Insert the key into the key switch on the left jamb of the elevator door, about 6.5 feet from the floor.
- Turn the key to the "ON" position, initiating recall.
Elevator Behavior in Phase One:
- Doors close and the elevator returns non-stop to the lobby.
- All corridor call buttons become inoperative.
- Door reopening devices and emergency stop buttons are inactivated.
- Visual indicators light up inside the elevator to show Phase One activation.

Phase Two: Fire Department Control

Initiation: Insert a second key from the key box into the "FIRE SERVICE" key switch in the elevator.
Key Characteristics: The key remains in the "ON" position and cannot be removed once activated.
Control Features:
- Firefighters can control the elevator using floor buttons.
- A button to cancel all registered calls is available.
- Elevator doors remain closed at landings other than the lobby, requiring continuous pressure on the door open button to access.
Safety Measure: If the elevator operates uncontrollably, turning the key to "OFF" will revert it to Phase One, returning to the lobby.

Elevator Status and Safety Measures

Any elevator not in Phase Two will stay at lobby level with doors open, preventing civilian access above the main floor.

Fire Alarm Activation

Regulatory Requirement: Buildings must have fire alarm devices that initiate elevator recall, effective from March 1, 2001.
Sprinkler Systems: Water flow alarm activation recalls elevators.
Smoke Detectors: Required in elevator lobbies and hoistways; two activated detectors will recall elevators.
Actions on Activation:
- Elevators return non-stop to the main floor upon activation in the machine room or hoistway.
- Activation on the main floor directs elevators to a pre-determined safe location.

Key Safety Notes

Emergency stop buttons are not functional in Phase One while the elevator is in flight.
Timing devices for door closure are disconnected in Phase Two.
Turning off Phase One does not affect cars already operating in Phase Two.
Phase Two cars must always return to the lobby when both phases are deactivated.
