What happens when phase l elevator service is activated?

When phase I elevator service is activated, it allows manual control of the elevator. This function is crucial during a fire emergency or similar situation, as it enables the elevator to be operated by designated personnel rather than becoming accessible through automatic call buttons. This manual control helps ensure that the elevator is used safely and appropriately, allowing trained personnel to utilize the elevator for emergency response or for evacuating individuals when conditions permit. Restricting access and allowing for manual operation reduces the risk of misuse and ensures safety protocols are followed during critical incidents.
