Motion 4000 Traction Elevator Control
1-14 Manual # 42-02-2P24
Fire Service Operation
There are many different fire codes that restrict or change elevator operation under fire condi-
tions. Please refer to “Fire Service Menu Options” on page 4-16. In general, fire service proceeds
in two stages; Phase I Fire Recall and Phase II Fire In-Car Operation. When a fire sensor or
switch is activated:
• The elevator will recall to the designated main or alternate recall floor. (Main if fire
detected on any floor other than the main floor; Alternate if fire detected on the main
recall floor. Or, as directed by a manually activated Fire switch.)
• The elevator will open its doors to allow any passengers to exit, then remain at the recall
floor until the in-car firefighter switch is activated. Once the in-car switch is activated the
car will run on Fire Phase II operation as allowed by the selected fire code.
Emergency Power Operation
Please refer to “EMERGENCY POWER OPERATION?/EMERGENCY POWER RETURN
FLOOR” on page 4-42. Emergency or standby power operation requires a backup power source.
For large buildings, this is typically a diesel or gasoline powered generator. When this is not
practical, backup power for a limited, rescue operation may be provided by a battery-powered
system like the MCE TAPS (Traction Auxiliary Power Supply).
Generator Backup
When power is lost, the elevator will come to a full stop. When emergency/backup power comes
on line, the elevator will be moved at programmed speed to a designated recall floor and the
doors will open to allow passengers to exit. The elevator will remain at the recall floor unless it
is designated to run under generator power.
TAPS Backup
When power is lost, the elevator will come to a full stop. When battery power becomes available,
the elevator will be moved at reduced speed to the nearest floor in the direction determined by
TAPS settings. At the floor, the doors will cycle, allowing passengers to exit, and then close. The
car will remain out of service until commercial power is again available and the TAPS unit
switches the car from battery power back to normal power. Please refer to the MCE TAPS man-
ual or data sheets for detailed information.
