For more information on the Bosch Smart Home Twinguard, you can view the corresponding data sheet or download theProduct pagevisit.

Further information on air quality

For further information on air quality, you can use various online resources. A good place to start could be the website of the Federal Environment Agency or the World Health Organization. There you will find extensive information on the various aspects of air quality, including the effects on health and tips on how to improve the air quality in your home.

Radio protocol of the Twinguard

Your Twinguard communicates with the Bosch Smart Home system via the encrypted ZigBee HA 1.2 protocol. In addition, manufacturer-specific protocol extensions are used to ensure a secure and reliable connection.

Measuring range of the Twinguard

The Twinguard can detect values between 500 ppm and 5500 ppm. Please note that there is an error tolerance of around +/- 15% for these limit values.

Limitations of the sensor

The sensor installed in the Twinguard cannot detect all organic components in the air. It must therefore make assumptions about other components of the air based on the gases detected.

Calibration after restart

After a restart or directly after teach-in, the Twinguard provides a best value of 500 ppm until the calibration allows more accurate values. Depending on the environment, this process can take up to an hour.

Measuring frequency of the VOC sensor in the Twinguard

The VOC sensor in the Twinguard constantly calibrates itself, using historical data from the last four days to provide accurate readings.

Effects of location changes

If you suddenly change the location of the sensor (e.g. due to outdoor installation), this may affect the measured values and not provide the expected results. Short-term location changes can falsify the database for the automatic calibration at the actual destination. We therefore recommend operating the Twinguard at the same location for a few days before using the measured values to assess its functionality.

Number of measured values

In a period of around 10 hours, the Twinguard generates around 120 measured values.

Changing the battery in your Twinguard

You will need six AA alkaline batteries for your Twinguard. Please note that lithium batteries are not suitable. We recommend the use of Panasonic or Duracell batteries.

After changing the battery

After you have changed the batteries, it is important to carry out a test alarm. You can do this either via the Bosch Smart Home app or directly on the device itself. This step ensures that your Smoke alarm is working properly.

Improving air quality without active ventilation

It is quite possible that the air quality in your home will improve even if you do not actively ventilate. This can happen due to the natural air exchange that takes place through small leaks in doors and windows. When no one is in the room, the air quality can therefore improve.

Air exchange in modern buildings

In newer, very well insulated buildings, the necessary air exchange is often generated by ventilation systems with heat recovery. Here too, the air quality can improve, even if you do not actively ventilate.

Importance of ventilation

Despite these natural improvements, regular ventilation is important to ensure optimum air quality. Your Twinguard will help you find the right time to do this.

Red flashing on your Twinguard

If your Twinguard regularly flashes red, this is a signal from the "Healthy indoor air" service. This service monitors the quality of the air in your room.

What does the red flashing mean?

The flashing red light is a friendly reminder that it's time to ventilate the room. So it's nothing to worry about, but a helpful hint to improve the air quality in your home.

Importance of ventilation

Don't forget to ventilate regularly to ensure healthy indoor air! It's a simple step that can make a big difference to your health and well-being.

Blue light on your Bosch Twinguard

Your Bosch Smart Home Twinguard is designed to constantly check its own functionality. The blue light you see is part of this self-check.

What does the blue light mean?

The Twinguard performs a self-check up to three times a day and indicates this with a blue light pattern on the LED strip. So if you see a blue light, it means that your Twinguard is performing its regular self-check.

Is that a good sign?

Yes, the blue light is a sign that your device is active and working properly. It indicates that your Smoke alarm is working reliably.
