What is the purpose of "fire service mode" in elevators?

The purpose of "fire service mode" in elevators is to enable firefighters to control the elevator in emergencies. This mode is specifically designed to enhance safety during a fire or other emergency situations. When activated, fire service mode restricts the use of the elevator to firefighters only, who can take control of the elevator and direct it to specific floors as necessary, thereby facilitating their operations and ensuring they can access areas quickly and safely.

This mode prevents regular users from calling or using the elevator during an emergency, which could lead to confusion or additional danger. The firefighters can override normal controls, making it a vital tool for emergency response. This functionality is essential as it allows first responders to efficiently manage their rescue efforts, particularly in high-rise buildings where stair access may be difficult.
