During an emergency, what task is assigned to the lobby security and engineering staff?

During an emergency, the task assigned to the lobby security and engineering staff is to perform fire determination tasks by the Annunciator panel. This role is critical because the Annunciator panel displays information about the status of alarms and the location of potential fire incidents within the building. By interpreting the signals from the panel, the staff can accurately assess the situation, provide essential information to emergency responders, and assist in coordinating the building's emergency response plan.

The focus of this task is to enhance safety by allowing for effective communication of fire-related information, which is crucial for making informed decisions about evacuations or other necessary actions. This responsibility emphasizes the need for staff to be alert, trained in monitoring alarms, and able to react quickly to protect the lives of occupants and facilitate emergency response efforts.
