Q-Series Temperature and Humidity Sensors
Check against the official notice below — it lists the full affected range.
Siemens is recalling wall-mounted temperature and humidity sensors used in commercial buildings, schools, and hospitals because they can overheat and create a fire hazard. The recalled sensors are Q-series models with model numbers beginning with QAA, QFA, or the model SB1-0834, available in white or beige with various cover designs and logos including Siemens, Talon, or Staefa Control System brands. The model number can be found on the sensor's circuit board inside the unit.
If a consumer has one of these sensors, they should first check whether it is currently operating on an AC power source. If it is, they should immediately have the sensor converted to a DC power source. Consumers should then contact Siemens to schedule installation of a free replacement sensor. Siemens is directly contacting owners of the recalled sensors.
