No, there are lots of ways to warn people of fires, some of them automatic and some of them require human input.
Human input: Someone shouting "fire" while pounding on your door often indicates that someone thinks there may be a fire. Pulling a manual alarm activation can trigger the fire alarm. Hearing fire-engine sirens stopping in front of your building is sometimes worth exploring further. There are numerous other ways.
Automatic: In addition to smoke detectors, there are also heat detectors that can activate an alarm. They may be set at a fixed temperature or may react to a rapid "rate of rise" of heat in the surrounding air. There are also flame detectors, which detect an IR or UV (or both) flickering light. One other sensor for automatic fire alarms is the water-flow alarm (meaning a sprinkler head is running).
