All of the following are components of a fire protection system EXCEPT?

Emergency lighting is crucial for safety during a fire event, as it provides illumination to enable safe evacuation. However, it is not classified as a component of a fire protection system in the way that the other options are.

Fire protection systems primarily aim to detect, control, and suppress fires. Sprinkler systems, standpipe systems, and fire alarm systems all directly contribute to fire suppression, notification, and prevention. Sprinkler systems automatically discharge water to control or extinguish a fire, standpipe systems provide a source of water for firefighters to combat fires, and fire alarm systems detect smoke or heat and alert occupants and emergency services.

While emergency lighting plays a supportive role in enhancing safety, it does not fall under the direct category of fire protection systems, which focus more specifically on active fire prevention and suppression mechanisms.
