The recall involves about 57,000 Q-Series temperature and humidity sensors manufactured by Siemens Industry Inc. (Buffalo Grove, Ill.). The sensors can overheat, posing a fire hazard. Four incidents of overheating and fires have been reported to Siemens: two were in schools and two in hospitals. Minor damage was reported, but no injuries.
This recall involves wall-mounted Q-series sensors that control heat, air-conditioning and humidity inside commercial buildings, hospitals and schools. The sensors come in three designs: a blank cover, a cover with a digital display screen or a cover with a digital display screen and door. The sensors are either white or beige and have a Siemens, Talon, Staefa Control System, Staefa Control System/Talon logo, or no logo. The recalled model numbers begin with QAA and QFA, and one with SB1. They are:
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
The model number is located on the sensor’s circuit board inside the unit. The units were sold by Siemens sales offices, partners, resellers and installers from June 2007 through August 2012 for between $200 and $400. They were manufactured in China and the United States.
You should look to see whether your sensors are currently operating on an AC power source and, if they are, you 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 also directly contacting owners of the recalled sensors.
