Comment on My CO2 / Smoke Detector Scared a Year off my life today, and I have questions. Long.

Certain types of smoke detectors dont detect ‘smoke’ or ‘steam’ exactly, but they monitor a small section of air in the unit and if there is enough particulate matter in the air the sensor is triggered and it goes off.
Because of this they are sensitive to aresols too, such as spray on deoderant.

This is almost certainly the correct answer. If it's a photoelectric-type detector it'll be set off by any interruption of the beam. This can be smoke, steam/vapor, dust, etc.
You can replace them with ionization type smoke alarms (or "dual type" alarms) and this will make it less sensitive to non-smoke interference.

This is also why vaping can set off smoke alarms.
