Where two or more elevators are controlled by a common operating system, all elevators shall automatically transfer to [emergency] standby power within 60 seconds after failure of normal power where the [emergency] standby power source is of sufficient capacity to operate all elevators at the same time. Where the [emergency] standby power source is not of sufficient capacity to operate all elevators at the same time, all elevators shall transfer to [emergency] standby power in sequence, return to the designated landing and disconnect from the [emergency] standby power source. After all elevators have been returned to the designated level, at least three elevators shall remain operable from the [emergency] standby power source.
