Siemens Industry of Buffalo Grove, IL, is recalling about 57,000 Q-series temperature and humidity sensors.
The sensors can overheat, posing a fire hazard. The company has had four reports of incidents of overheating and fires. Two of the fires were in schools and two in hospitals. Minor damage was reported. There were no injuries reported.
The 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 sensors, manufactured: China and the U.S., were sold by Siemens sales offices, partners, resellers and installers from June 2007 through August 2012 for between $200 and $400.
Consumers should look to see if their sensors are currently operating on an AC power source and, if they are, they should immediately have them 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.
Consumers may contact Siemens at (800) 516-9964 from 7 a.m. to 5:30 p.m. CT Monday through Friday.
