Twinguard - General Information
Significance of room types in the Bosch Smart Home Twinguard
The Twinguard has preset settings for different room types that affect both the sensitivity of the smoke alarm and the ideal ranges for air quality parameters.
Fire alarms and room types
The sensitivity of the fire alarm is determined by the room type. For example, the Twinguard is less sensitive to disturbances such as cooking vapors in the "Kitchen" room type. In the "Bedroom" and "Children's room" room types, the Twinguard responds with the highest sensitivity. You can customize these settings individually if needed.
Air quality and room types
The ideal ranges for air quality parameters vary depending on the room type. These ranges are visible in the green-highlighted areas in the air quality chart. For example, lower temperatures are set as the ideal range for the "Bedroom" than for the "Office". You can also customize these settings individually if needed.
With these settings, you can optimally adapt the Twinguard to the needs of each room in your home.
How the Bosch Smart Home Twinguard works without app and Smart Home Controller
Yes, the Bosch Smart Home Twinguard can also be operated without connection to the app and Smart Home Controller, but with limited functions. In this case, the Twinguard only functions as a local smoke detector and can trigger fire alarms.
Please note that in this mode, no alarm forwarding to other Twinguards and Bosch Smart Home smoke detectors takes place. For the full range of functions and optimal use, we recommend connecting to the app and the Smart Home Controller.
Measurement frequency of the VOC sensor in the Twinguard
The VOC sensor in the Twinguard constantly calibrates itself and uses historical data from the last four days to deliver accurate measured values.
Effects of location changes
If you suddenly change the location of the sensor (for example by mounting it outdoors), this can affect the measured values and not deliver the expected results. Short-term location changes can distort the data basis for automatic calibration at the actual destination. Therefore, we recommend operating the Twinguard at the same location for a few days before using the measured values to assess functionality.
Number of measured values
In a period of approximately 10 hours, the Twinguard generates around 120 measured values.
Measurement range of the Twinguard
The Twinguard can detect values between 500 ppm and 5500 ppm. Please note that there is an error tolerance of approximately +/- 15% at these limit values.
Sensor limitations
The sensor installed in the Twinguard cannot detect all organic components of the air. Therefore, it must make assumptions about other components of the air based on the detected gases.
Calibration after restart
After a restart or directly after pairing, the Twinguard provides a best value of 500 ppm until calibration allows for more accurate values. This process can take up to one hour depending on the environment.
Delivery Scope of the Bosch Smart Home Twinguard
The delivery scope of the Bosch Smart Home Twinguard typically includes:
1. The Twinguard smoke detector with air quality sensor
