The choice that is identified as not being a fire detection device is indeed appropriate because it does not function primarily to detect the presence of fire. A smoke damper detector is designed to monitor the operation of smoke dampers rather than to detect fire itself. Smoke dampers are components of fire protection systems that help control the movement of smoke within a building, and while they play a critical role in passive fire protection, their detectors do not serve the primary function of identifying fire.

In contrast, the other devices listed are specifically categorized as fire detection devices. A smoke detector identifies smoke as an indicator of a fire, used to alert occupants of danger. A heat alarm senses the increase in temperature associated with a fire. A flame detector detects the presence of flames through various means, including infrared or ultraviolet light detection. Each of these plays a key role in alerting to the presence of fire, thereby ensuring safety and prompt response to potential fire hazards.
