True or False: Smoke detectors detect flame, heat, and compressed gases.

Smoke detectors primarily function by detecting particles produced from combustion, which is emitted during a fire that generates smoke. Traditional smoke detectors come in two main types: ionization and photoelectric. Ionization smoke detectors are sensitive to fast-burning fires that produce small particles, whereas photoelectric detectors are better at identifying smoldering fires that produce larger particles of smoke.

However, smoke detectors do not specifically detect flame, heat, or compressed gases. While heat detectors are a separate category of fire detection that responds to an increase in temperature, smoke detectors are solely focused on sensing smoke particles. Therefore, saying that smoke detectors detect flame, heat, and compressed gases is incorrect. This understanding clearly illustrates why the statement is false.
