Welcome
Congratulations on purchasing your Bosch Smart Home Twinguard Smoke Alarm. It will help you to make your home even safer and smarter. The Twinguard Smoke Alarm can do more than just detect smoke. Its integrated LED lights up the escape route in case of an emergency. An air quality sensor measures not only room temperature, but also relative humidity and volatile organic compounds (VOC) of the air. For greater safety and comfort, you can interconnect multiple Twinguard Smoke Alarms through the Gateway.
We hope you enjoy your new product.

Product Description
The Twinguard is a Smoke Alarm manufactured to EN 14604: 2005/AC: 2008, which connects wirelessly to a Gateway. It is equipped with the following functions and components:
- Audible alarm
- 360° light strip for visual signals
- Radio module
- Alarm LED
- Emergency lighting
- Air quality sensor
- Smoke sensor
- Large operating button
- Batteries
The product reliably warns you of potential fires in your home. If smoke is detected, both a visual and audible alarm is triggered.
The Gateway links all the Twinguard Smoke Alarms installed in your home and enables the connection to your mobile device, so if an alarm is triggered, a notification is forwarded to your phone.
Intended Use
The product is intended for indoor use in residential buildings. It should only be used together with original Bosch Smart Home components.
- Follow the safety instructions and the directions in this manual and the Bosch Twinguard App to ensure that the product is set up correctly.
- Observe the connection conditions, ambient temperatures, and humidity limits in the Technical Data section (see p. 40).
- Avoid installing in areas prone to high amounts of direct sunlight or near to sources of heat or cold.
Up to 40 Twinguard Smoke Alarms can be connected to one Gateway.
Only one Gateway can be set up with your Twinguard Smoke Alarms.

Installation and Set Up
Before You Start
In order to set up the Twinguard, your mobile device must be connected to the same WiFi network that your gateway is connected to. Follow the instructions in the Bosch Twinguard App to add more smoke alarms.
Starting the Bosch Twinguard App
Now start the Bosch Twinguard App and log in using your username and password under “Login”. If you do not have a Bosch Account, you can create one using the app.
You can also use your Bosch Account for other Bosch devices you want to interconnect in a network. If you already have a Bosch Account for another service, you can use it to log in directly.
To add another smoke alarm, follow the App: click in the menu → rooms → add new Twinguard. From this point, the app guides you through the installation process.
Set Up More Smoke Alarms
In order to set up the Twinguard, your mobile device must be connected to the WiFi network that your Gateway is already connected to.
Follow the instructions in the Bosch Twinguard App to add more Smoke Alarms.
This will require scanning the QR code found on the back of each Smoke Alarm.
Activating the Twinguard
When prompted by the app, activate the Twinguard Smoke Alarm by removing the red pin on the back.
The Twinguard will become operational when the red pin has been removed. Please note that inadvertently pressing the operating button will trigger a test alarm.
Mounting the Twinguard
Mounting Instructions
It is best practice to install several smoke alarms in your home to be fully protected. As a minimum, we recommend that they are installed in every Bedroom, Kids room, and in all hallways that serve as an escape route. For maximum effectiveness, we recommend that additional smoke alarms should be installed in living areas, attics, and basements.
A diagram illustrates recommended (✔️) and not recommended (❌) mounting locations within a house layout. Icons depicting a car, bell, window, fire, sink, faucet, fan, and dustbin are shown with 'X' marks, indicating unsuitable locations.
The Smoke Alarm should be mounted on the ceiling; it is important to note certain factors when choosing the best position.
- Mount the device in the center of the ceiling. The maximum monitoring area of an alarm is 60 m². In large rooms, an extra alarm should be fitted for every 60 m². The maximum height a smoke alarm should be installed is 6 m.
- If being installed in Hallways (maximum 3 m wide), a smoke alarm must be installed at least every 15 m along the length of the hallway. There should be no more than 7.5 m from a smoke alarm to the end of the hallway. We recommend that a smoke alarm is installed at all hallway junctions and corners.
- In rooms that are divided into multiple floors, it is recommended that a smoke detector is installed on each level where the ceiling area is greater than 16 m², and the length and width is over 2 m.
- If your ceiling is split by beams or joints that protrude greater than 0.2 m, we recommend that multiple Smoke Alarms are fitted if the ceiling area created by the beams is greater than 36 m².
Diagrams illustrate recommended mounting distances and angles for smoke alarms on ceilings, including dimensions like '> 1m', '0.5-1m', '> 20°', and '0.5m'.
The kit includes two 3.5 x 30 mm countersunk cross-head screws and two 5 mm universal wall plugs, which are suitable for fitting to concrete ceilings.
Align the straight edge of the mounting bracket parallel to the ceiling edge of the desired room so the Smoke Alarm is parallel to the edge of the room.
Fixing with Screws
Follow these steps to fix the mounting bracket:
- Hold the mounting bracket in the desired position.
- Mark the drill holes.
- Drill the holes and insert the plugs.
- Position the mounting bracket and screw it on.
A diagram shows the smoke alarm being fitted to the mounting bracket and rotated until it clicks. The text "Click" is displayed.
When you hear a “Click”, your Twinguard is mounted correctly.
Maintenance Instructions
Visual Inspection
- Check that the smoke inlet openings, the 360° light strip, and the sound outlets are not clogged (e.g., by dust, dirt, or paint).
- If necessary, clean the Smoke Alarm carefully with a damp cloth.
- Check for any damage and that the bracket is still firmly fixed in place.
- Ensure that there is a clear space of 0.5 m around your Twinguard so smoke detection is not hindered.
Functional Test
We recommend that you test your Twinguard immediately following installation and every month thereafter. It should also be checked following every battery change and software update.
To perform the test, briefly press the operating button. The alarm will sound three times at a reduced volume, the alarm LED and the LED light strip will flash red, and the emergency lighting will turn on.
If the functional test was successful, the 360° LED light strip will light up blue for one second.
By initiating a test or muting an alarm using the operating button, fire detection is deactivated for the next 10 minutes. If initiated or muted using the App, detection remains active.
Alarm and Troubleshooting
Faults
The following table lists common audible and visual signals, their causes, and recommended measures:
| Audible signal | Visual signal | Cause | Measure |
|---|---|---|---|
| Quiet signal, every 43 s | Yellow LED flashes 3 times every 43 s | Alarm faulty | Replace the Alarm |
| Quiet signal, every 300 s | Yellow LED flashes once every 300 s | Batteries nearly empty | Replace the batteries |
| Quiet signal, sounds every hour | - | Alarm OK, but batteries in one of the other alarms in the network are nearly empty | Look for an alarm whose 360° circumferential LED light strip is flashing yellow (once every 300 s) and replace its batteries. |
Switching off the Smoke Alarm
If the alarm is triggered, please press the operating button in the center of the Smoke Alarm to mute it.
Alternatively, you can silence the alarm using the Twinguard App.

Faults in Radio Operation
Faults in radio operation (e.g., due to electric motors or defective electrical devices) cannot be ruled out. The radio range inside buildings may differ greatly from the radio range in free-field conditions. Apart from the transmission power and the receiver characteristics, environmental influences such as humidity and structural characteristics may also influence radio operation.
