Twinguard help

To mount the Bosch Smart Home Twinguard, use the enclosed dowels and screws. The Twinguard is not intended for adhesive mounting. For more information, see theInstruction manual.

Typically, the Twinguard requires 15 to 20 minutes to complete calibration after initial installation.

To install the Bosch Smart Home Twinguard, you need the Bosch Smart Home app as well as an already installed Smart Home controller and the accessories included in the package. The Bosch Smart Home App guides you through the individual installation steps.

Please also see our installation video in this article and on ourBosch Smart Home Youtube Channel.

Please also note theOperating/installation instructions.

If you are unable to connect your Twinguard, please check the following:

Press the control button on the Twinguard for more than four seconds. The Twinguard will then try to connect to the Smart Home controller again.

Try moving the Twinguard closer to your Smart Home controller and restart the scan. The range of your Smart Home controller is approximately the same as your WLAN router.

If the previous two steps were not successful, reset the Twinguard to factory settings and restart the installation.

The air quality sensor must calibrate itself once. After initial installation, the air quality sensor requires up to two hours until it can perform the first measurements. Within the first 48 hours after commissioning, a recalibration is performed to optimize the quality of the recorded data.

There are several reasons why the measured values of the Twinguard are listed in the diagram with gaps. Especially if the gaps occur only rarely and for short periods of time. However, this is not expected to have a negative effect on the overall functionality of the Twinguard.

The following reasons are usually responsible for gaps:

1. the Smart Home controller has been restarted or updated. During the restart, it is normal that there is a gap of about 15 minutes in the diagram.

2. the connection between Smart Home controller and Twinguard is not stable. Sources of interference such as Wi-Fi or other electrical devices may be responsible for this.

3. the distance between Smart Home controller and Twinguard is too long. This can be compensated for by a Smart plug compact, as this can extend the range.

4. the battery of the Twinguard is almost empty. In order to continue to provide the safety-relevant Smoke alarm, the Twinguard automatically deactivates the measurement of the air quality for energy-saving reasons when the batteries are almost empty.

5. The end of the recording history has been reached. Only the data from the last 90 days is retained.

The Smoke alarm is not affected by the disconnection. However, a connection to the Smart Home controller is necessary to alert other Smoke alarms in the system as well and to send a notification to the smartphone.

When removing a Twinguard via the app, all Twinguard-specific data in your Bosch user account is deleted in the Bosch Cloud. This is, for example, all data that you specified when commissioning the system, as well as all historical air quality data recorded over time. Only the Bosch user account you created remains.

As soon as it is determined for the Twinguard that the batteries will not last much longer, the following phases are initiated:

35 days before the battery is empty: A message is displayed in the app that the battery needs to be replaced. In addition, the LED strip of the Twinguard lights up in orange.

30 days before the battery is empty: The detector starts beeping loudly. After the second phase, the batteries will last for about 30 days, but should be replaced at this stage.

If the battery status of your Twinguard constantly decreases over time, the air quality sensor will switch itself off at a certain point in time in order to make the remaining low battery capacity entirely available to the Smoke alarm protection function.

If the app shows you a "battery empty" icon, you have at least 30 days of battery life left excluding the smoke alarm function.

When new batteries are inserted, the air quality sensor activates again automatically.

After inserting new batteries, do not forget to perform a test alarm.

The flashing and fault codes and their meaning for the Bosch Smart Home Twinguard can be found on page 16 in theInstruction manual.

To reset the Twinguard to its factory settings, please proceed as follows:

First remove at least one battery. Wait 20 seconds or press the operating button of your Twinguard again briefly after removing the battery. In this way, you ensure that the restoration of the factory state can be carried out successfully.

Then reinsert the battery and press and hold the center of the control button while inserting it.

The detector will now start with a fast flashing orange light.

Release the control button briefly and then immediately press the control button on the detector again for at least four seconds until you hear a short audible signal and a single flashing green light indicates that the factory settings of your Bosch Twinguard have been successfully restored.

The Twinguard then restarts and is in pairing mode, i.e. it can now be taught in again.

If you move a Twinguard from one room to another, please follow the instructions for disassembly/assembly of the hardware in theInstruction manual.

To ensure both the predefined optimal air quality ranges and the correct detector sensitivity in case of fire for the new room, perform the following steps in your Bosch Smart Home app:

Remove the Twinguard from the app that you want to install in another room.

Reset the detector to the factory settings.

3. now add the detector for the new room where you want to install it.

Note: By moving to a new room, the history of the air quality data of the previous room will be lost. A simple renaming of the room can be done at any time directly in the Bosch Smart Home app.

Yes, the Twinguard can be used in the Bosch alarm system. If you have activated the "Alarm system" service (found under the "Services" menu item), all connected Bosch Smart Home Smoke alarms and Twinguards will emit an acoustic signal.

The prerequisite for this is that the "Audible alarm" action is set to "On" in the alarm system.

If you still have questions or problems with the integration, accessibility or use of the device, please feel free to contact ourCustomer support.

Yes, you can use the various measured values of the Twinguard as triggers for automations.

To do this, go to "Scenarios" and then to "Automations".

Then select "Add automation".

3. now select your desired parameter under IF and your desired reaction under THEN. For example: IF "air quality moderate" THEN "smart plug" on.

The lower limit of the installed sensor (BME680) is a value of 500 ppm. The highest detectable value is 5500 ppm. For both limit values, an error tolerance of approx. +/- 15% must be taken into account.

The installed sensor cannot detect all organic components of the air. Thus, it must also make assumptions about other components of the air depending on the gases detected.

The best value of 500 ppm is also supplied after a restart (or directly after teach-in) until the calibration allows more accurate values. This process can take up to approx. one hour depending on the environment.

The VOC sensor constantly calibrates itself to provide the best possible values in the environment used. The algorithm uses historical data from the last 4 days, among other things. If the environment of the sensor is changed abruptly (e.g. mounting outside), this does not necessarily have the effect expected. A short-term adjustment of the installation location thus falsifies the data basis for the auto-calibration at the actual destination. If possible, the Twinguard should therefore be operated at the same location for a few days before the values are used to interpret its functionality. Approximately 120 measured values in a period of 10 hours can be assumed.

Detailed information on the scope of delivery and the technical data of the Bosch Smart Home Twinguard can be found at theProduct page.

Bosch Smart Home stores your data in the Bosch Cloud for three years.

This gives you retroactive access to the air quality history recorded at your site for three years, after which it is automatically deleted.

However, you can also delete your data beforehand by resetting the system to factory settings and removing the components from the Bosch Smart Home app.

The Bosch Smart Home Twinguard performs a continuous measurement of the air quality. Temperature, relative humidity and air purity (detection of volatile organic compounds) are taken into account.

The Bosch Smart Home Twinguard is certified according to the European standard EN 14604:2005 + AC:2008, making it a reliable lifesaver in your home.

Bosch Smart Home Twinguard is the world's first 2-in-1 Smoke alarm. It is a combination device consisting of Smoke alarm with Dual-Ray technology and air quality sensor.

With the help of the Bosch Smart Home App, you are always connected to your Twinguard to be quickly informed about smoke alarms in your home even when you are on the move.

In addition, you have access to your air quality data at any time.

More information about the Bosch Smart Home Twinguard can be found in the corresponding data sheet and at theProduct page.

Further information on the subject of air quality can be found at the following linkLink.

Communication between Twinguard and Bosch Smart Home System is encrypted using a ZigBee HA 1.2 protocol and proprietary, manufacturer-specific protocol extensions.

You will need six AA size alkaline batteries for your Twinguard.

Lithium batteries must not be used for the Twinguard. Please use only batteries from the manufacturers Panasonic or Duracell.

Perform a test alarm after each battery change, either via the Bosch Smart Home app or by pressing the control button on the device itself, to ensure that your Smoke alarm is working properly.

In apartments/houses that are not low-energy or passive houses, there is a permanent exchange of air due to leaks in doors and windows. It is therefore normal that the air purity improves when no one is in the room, even if it is not ventilated.

In new, very dense buildings, one tries to generate this necessary air exchange by ventilation systems (with heat recovery). Here, too, the air improves.

When using the "healthy indoor air" service, the Twinguard will flash red at regular intervals to remind you to ventilate the room.

The Bosch Smart Home Twinguard continuously performs self-diagnosis. If anything is wrong, you will be informed about it. So you can always be sure that your Twinguard Smoke alarm is working reliably. Up to three times a day you can also see this check. This is indicated by a blue light pattern on the surrounding LED band.

As a Smoke alarm and as an air quality sensor, the Twinguard has different setting options specified by the manufacturer and designed for the corresponding rooms.

Fire alarms:The sensitivity of the fire alarm is determined via the room types. For example, for the "Kitchen" room type, the Twinguard is less sensitive to disturbance variables such as kitchen fumes. In the "Bedroom" and "Children's room" room types, the Twinguard Dual-Ray detector reacts with the greatest possible sensitivity. If required, you can adjust the optimum ranges individually in the follow-up.

Air quality:Depending on the room type, different ideal ranges are specified for the air quality parameters. The ideal ranges for each room type can be identified by the green highlighted areas in the air quality diagram. For "Bedroom", for example, lower temperatures are provided as the ideal range than for "Study". If necessary, you can adjust the ideal ranges individually afterwards.

Yes, but with restrictions. If the Twinguard is not operated as a smart Smoke alarm with Internet connection, a reduced range of functions is available. In this case, the Twinguard can only display fire alarms as a local Smoke alarm. In this case, there is no alarm forwarding to other Twinguards and Bosch smart home Smoke alarms.
