Recall humidity sensor1 School and Hospital Fires Lead To Recall Of Q Series Temperature and Humidity SensorsAfter 4 incidents of sensors causing fires in schools and hospitals, the Consumer Product Safety Commission (CPSC) and Siemens Industry, Inc. are recalling around 57,000 Q-Series Temperature and Humidity Sensors.

The recalled sensors control heat, air conditioning and humidity within commercial buildings, hospitals and schools. The sensor was available in three separate designs:  a blank cover, a cover with a digital display screen, or a cover with a digital display screen and door. Also, the sensors came in either white or beige and have a Siemens, Talon, Staefa Control System, Staefa Control System/Talon logo or no logo. The recalled model numbers can be found on the sensor’s circuit board inside the unit and are as follows:

QAA 2060, QAA 2063, QAA 2072, QAA 2073
QFA 2000, QFA 2001, QFA 2060, QFA 2071, QFA2072, QFA 3000, QFA 3001, QFA 3060, QFA 3071, and SB1-0834

Manufactured in both China and the United States, the recalled sensors were sold by Siemens sales offices, partners, resellers and installers for between $200 and $400 from June 2007 through August 2012.

If you currently own a recalled Q-Series Temperature and Humidity Sensor, please check to see if it is operating on an AC power source. If so, immediately have the recalled sensors converted to a DC power source and contact Siemens to schedule your installation of a free replacement sensor. Siemens is already contacting owners directly regarding the recalled sensors.

To contact Siemens for further information, please call (800) 516-9964 from 7 a.m. to 5:30 p.m. CT Monday through Friday, or visit them online at and go to Product Safety Recall.
