Which method falls under visual relaying methods?

• A. Direct radio communication
• B. Alarm-receiving equipment
• C. Scrolling message boards
• D. Telephone calls

Answer: (C)

Visual relaying methods are designed to convey information through visual means, making it accessible to individuals who may not be able to hear or receive information through auditory channels. Scrolling message boards utilize a digital display that updates information in real time. They visually convey messages, alerts, or important information in an easy-to-read format, making them highly effective for communication in environments such as fire stations, public spaces, or workplaces during emergencies.

Direct radio communication and telephone calls primarily rely on auditory channels to relay messages, while alarm-receiving equipment typically provides auditory alarms rather than visual signals. These methods do not focus on visual representation, making them distinct from visual relaying methods. Scrolling message boards clearly align with the definition of visual relaying, as they provide critical information that can be quickly read and understood visually by the intended audience.
