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.
