Which notification appliance provides visual indication for alarms?

Explanation:
Visual notification is provided by devices that emit light. A strobe flashes bright light when the alarm activates, giving a visual cue that an alarm is occurring. Sirens, bells, and speakers produce sound (audible alerts) but don’t provide a visual indication. So the device that delivers the visual signal is the strobe.
