What is the purpose of Phase One in Fire Department Elevator Recall?

The purpose of Phase One in Fire Department Elevator Recall is to cancel all registered calls in the elevator. When a fire alarm is activated, it is crucial for elevator operations to prioritize the safety of occupants and emergency responders. Phase One specifically addresses this by resetting the elevator to prevent it from stopping at floors where emergency responders might need to access. By canceling all calls, it ensures that the elevator does not serve any routine requests, which can compromise safety during a fire incident. Instead, the elevator system is prepared for emergency operations where firefighters can use it to reach the needed floor without interruptions from normal use.

This phase serves as a critical measure to ensure that firefighters and emergency personnel can respond quickly and effectively without the elevator serving regular calls that could hinder their access to the scene of the incident. In essence, it helps to streamline emergency response and minimize the risk associated with elevator use during a fire emergency.
