Siemens recalls Q-series temperature/humidity sensors for schools and buildings due to fire risk from overheating. Affected models include QAA 2060, QAA 2063, and others. Consumers must switch to DC power or get free replacements.
The sensors can overheat, posing a fire hazard.
Siemens is recalling Q-series temperature and humidity sensors used in schools, hospitals, and buildings because they can overheat and cause fires. Owners should switch to DC power or get a free replacement sensor from Siemens.
The sensors can overheat when connected to AC power, potentially causing a fire. This happens because the sensors are designed to run on AC power but the overheating risk requires a switch to DC power to eliminate the hazard.
Schools, hospitals, and commercial buildings using Siemens Q-series sensors are affected. People with sensors operating on AC power are most at risk.
Check for sensors with model numbers starting with QAA, QFA, or SB1. They are white or beige with Siemens, Talon, or Staefa logos. The model number is on the circuit board inside the sensor.
If your sensor is currently on AC power, immediately switch it to DC power to prevent overheating and fire risk.
Contact Siemens to schedule installation of a free replacement sensor once you've switched to DC power.
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.
The recalled models include QAA 2060, QAA 2063, QAA 2072, QAA 2073, QFA 2000, QFA 2001, QFA 2060, QFA 2071, QFA 2072, QFA 3000, QFA 3001, QFA 3060, QFA 3071, and SB1-0834.
Check for sensors with model numbers starting with QAA, QFA, or SB1. They are white or beige with Siemens, Talon, or Staefa logos, and the model number is on the circuit board inside the sensor.
No, but if your sensor is on AC power, switch it to DC power immediately to prevent overheating and fire risk.

Subject: Recall 1492 — Siemens Q-Series Temperature and Humidity Sensors Hello, I own a Q-Series Temperature and Humidity Sensors that is covered by recall 1492 from Siemens. The official recall notice states: 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. I’m writing to arrange the remedy described in the recall (a refund, repair, or replacement as applicable). Could you please tell me the next steps to resolve this? Thank you.
