A red light acknowledges to the user that the phone has been activated in case the user is hearing impaired. The main security control center is adjacent to the main entrance. From the control center, security officers monitor security alarms, fire alarms, emergency elevator controls, public address systems, and intercoms. All of the power and lighting for the security office has an emergency backup power supply. Alarms are connected to the U.S. Marshals service in the federal courthouse across the street.
Alarms ring in both facilities.
If a fire alarm is activated in the Federal Justice Building, an alarm rings in the federal courthouse. While the system causes duplication of alarms, if an emergency or natural disaster disables the security office in one building, the other will be aware of the problem. All emergency exit doors are equipped with an approved emergency egress system. All points of entry for utility services and environmental controls are secured. All air intakes, vents, and grills are designed to be inaccessible and secure against projectiles such as smoke bombs.
