Area of Rescue Assistance
An "Area of Refuge" or "Area of Rescue Assistance" is defined as an area which has direct access to an exit, where people who are unable to use the stairs may remain temporarily in safety to await further instructions or assistance during emergency evacuation. An ARA system is a voice communication system which is initiated by depressing the call station button, transmitting the signal to a central annunciator panel and automatically dialing out on a phone line to announce the call to emergency services. A single pulse tone and a flashing light signals the caller that the alarm has been received. The control station can then talk to the caller. The caller need not take any other action to communicate with the control station.
