A notification appliance is a device designed to alert or notify occupants of a building about a fire or other emergency situations, generally through visual or audible means. Strobe lights and audible alarms are classic examples of notification appliances since they serve the direct purpose of informing individuals in a space that there is a fire emergency that requires immediate attention and action.

The strobe light provides a visual alert that can be critical for individuals who are deaf or hard of hearing, while audible alarms inform everyone present about the necessity to evacuate or take appropriate action during a fire event. Together, they enhance the effectiveness of a fire alarm system by ensuring that all occupants are alerted irrespective of their sensory capabilities.

In contrast, smoke detectors, heat sensors, and manual pull stations serve different roles within a fire alarm system. Smoke detectors and heat sensors are detection devices that sense the presence of smoke or heat, triggering the alarm system. Manual pull stations are used to activate the alarm manually but do not provide notifications themselves. Therefore, the choice that exemplifies a notification appliance is the strobe light or audible alarm.
