Which component provides a visual alert in a fire alarm system?

• A. Speaker
• B. Smoke detector
• C. Strobe Light
• D. Heat detector

Answer: (C)

Visual notification in a fire alarm system is provided by devices that emit a visible signal when the system is active. A strobe light flashes to grab attention visually, making it the component that delivers the visual alert. This is especially important for people who are deaf or hard of hearing, or in noisy environments where audible alarms alone might be missed. The other devices have different roles: a speaker produces the audible alarm, while smoke detectors and heat detectors are sensing devices that trigger the system but do not themselves flash a visual cue. So the strobe light is the element that supplies the visual alert.
