CPSC campaign 13720
Hazard
The sensors can overheat, posing a fire hazard.
Remedy
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.
