Siemens has recalled approximately 57,000 Q-series wall-mounted temperature and humidity sensors used in schools, hospitals, and commercial buildings. These sensors, sold between June 2007 and August 2012, can overheat, which has already led to four reported fires. The affected units come in three designs—blank, with a display, or with a display and door—and are available in white or beige. Siemens is providing free replacement sensors to all affected customers and will handle the installation.
The internal components of the sensors can overheat when connected to an AC power source, posing a fire risk. Four incidents of overheating and fires have been reported in school and hospital settings.
Consumers should look to see if their sensors are currently operating on an AC power source and, if they are, consumers should immediately have the recalled sensors converted to a DC power source. Consumers should contact Siemens to schedule the installation of a free replacement sensor. Siemens is directly contacting owners of the recalled sensors.
