No, the Smart Home Smoke alarm is only suitable for apartments and residential houses.

Check whether the Smoke alarm can still be controlled manually (test alarm). If this is the case, it is possible that the distance between the controller and the component is too great or that other products are having a disruptive effect on the connection.

You can use the repeater function of the Smart Home plug to improve the connection quality if necessary.

Make sure that the Smoke alarm is at least 1 meter away from the controller when testing.

No, this is currently not possible.

Your Bosch Smart Home Smoke alarm has a function test that you can trigger at any time using your app.

Open corresponding Smoke alarm in your app >> Display additional functions >> Start test alarm

Adhesive mounting of the Smoke alarm is only suitable for smooth surfaces, e.g. wood veneers or painted metals. Plastered surfaces do not provide sufficient long-term adhesion due to their coarse porosity.

In the case of plastered concrete ceilings, plaster may even peel off over a large area, e.g. when a detector is dismantled. Further information can be found in theInstallation instructions.

In the event of a smoke alarm, not only the reporting Smoke alarm triggers, but also all other Smoke alarms integrated in your system. Via push message and in your app, you can see at any time in which room the alarm was triggered.

The same applies to the burglar alarm. If you have activated the auditory alarm, all connected Smoke alarms will trigger with a corresponding signal tone.

To mount the Bosch Smart Home Smoke alarm, purchase and use 3M™ VHB™ Adhesive Tape 5952.

The QR code is located on the back of your device.

If the power should fail in the event of a fire, it can be difficult to find your way around, especially at night. That's why the Smoke alarm is equipped with an emergency light. It safely shows you the way out of the danger zone as soon as the alarm is triggered.

Yes, the Bosch Smart plug can act as a repeater/signal amplifier here. To activate the range extension of the Smart plugs, open the device settings of the Smart plug and activate the item "Range extension".

You can integrate a maximum of 40 Smoke alarms into your Smart Home system.

Smoke alarm should be installed in all living rooms (living room, bedroom, hallways). Smoke alarms are not suitable for other rooms, such as the kitchen.

You can find more information inthe operating instructions.

An alternative for these special rooms can be the Twinguard, which can be configured to room types. Find out more about this under the followingLink.

Make sure the Smoke alarm is within range of your Smart Home controller. If you cannot connect your Smoke alarm, you have the following options:

1. perform the installation again. To do this, check whether the device has already been detected (within the "Devices" menu item) and remove it if necessary.

Perform a reset on the Smoke alarm before installing it again. Several resets may be necessary.

Make sure that the Smoke alarm is at least 1 meter away from the controller at the time of re-learning. Please also note our reset video on this page or on ourBosch Smart Home Youtube Channel.

When the test alarm is triggered, no notification is sent to your cell phone as a matter of principle.

If you want to test the full functionality of the Smoke alarm, you can do this with the help of a test spray (available in hardware stores or online retailers).

If a Smoke alarm detects smoke for less than 10 seconds, the other Smoke alarms in the system are informed, but not the Smart Home controller. The Smoke alarm leaves the alarm state when no more smoke has been detected (alarm ended). This means that the Twinguards integrated in the system are not set to alarm status.

In the event of a false alarm from a Bosch Smart Home Smoke alarm, the smoke chamber should be checked for debris. If you have any queries, please do not hesitate to contact theServiceturn.

No. A non-replaceable 3 V lithium battery is installed in the Smoke alarm. You will be informed in good time via your app and acoustically via the Smoke alarm when the capacity of the battery is about to be exhausted. Then replace the Smoke alarm.

Your Bosch Smart Home Smoke alarm/Twinguard starts emitting a loud signal. All other installed Bosch Smart Home Smoke alarms and Twinguards will also trigger.

All connected smart lights will turn yellow and the Light controls will come on to illuminate your escape route.

All integrated Shutter controls raise the shutters to clear the escape route.

In addition, you receive a notification on your smartphone and can alert the fire department directly via your app. You can mute the additional Smoke alarms and Twinguards via the app.

For safety reasons, you cannot deactivate the failing Smoke alarm via the app.

To perform a reset on your Bosch Smart Home Smoke alarm and reset it, follow these steps:

Unscrew the Smoke alarm from the socket and wait 30 seconds.

Press and hold the button of the Smoke alarm.

Screw the Smoke alarm back into the socket.

After a short time, the Smoke alarm should flash orange.

Release the button briefly, press it again and hold it down until the flashing stops.

Release the button. If the reset is successful, the Smoke alarm flashes green briefly and orange every 10 seconds. If the reset is unsuccessful, the Smoke alarm flashes red once.

After the successful reset, the Smoke alarm can be set up again as usual. For this, please also note our reset video on this page or on ourBosch Smart Home Youtube Channel.

Besides the known deactivation in our Smart Home app, you have the following additional options to deactivate:

1. scenario "Coming home" as assignment on the Smart Home Universal switch/Universal switch Flex

2. scenario "Coming home" as assignment on the Twist. Smoke alarms and Twinguards are muted after 5 minutes. However, the Phillips Hue lamps continue to flash red. The alarm condition will continue to be maintained until deactivated by the user.

By pressing the operating button, i.e. with triggering of the test alarm, the detector goes into hush mode (muting) after 3x flashing. This runs for 10 minutes. After 10 minutes, it returns to normal mode (operation mode).

So during these 10 minutes you can start actions like drilling or cooking without the Smoke alarm detecting an alarm - this is signaled by the flashing.

This has no effect. For security reasons, the burglar alarm can only be deactivated in the Bosch Smart Home app. This means that a burglar cannot deactivate the alarm on his own.

In this case, the alarms will stop at those networked Smoke alarms to which the alarm was forwarded. Only the alarm at the triggering Smoke alarm remains active.

Yes, the Smoke alarm emits three tones in quick succession when the burglar alarm is triggered. The Smoke alarm emits tones at regular intervals, similar to other common smoke alarms.

Smoke alarms must be regularly maintained and their function checked. The responsibility for installation and maintenance varies by federal state in Germany.

Whether tenants or landlords are responsible for maintenance and installation is regulated in the relevant state building code and in the application standard for Smoke alarms (DIN 14676).

A function test can be made on site via the control button on the Smoke alarm or via the app. The distinction according to the responsibility between landlord and tenant is important because the app and the private data of the Bosch Smart Home user linked to it are not intended for the landlord in a tenancy relationship. In addition, the Bosch Smart Home Smoke alarms do not offer the possibility for landlords to perform maintenance and a functional test via remote access and to create a log of this test.

The above information applies to Germany. In Austria, UK and France, other regulations may apply. Bosch Smart Home recommends a monthly check beyond the legal requirement.

Yes, the design of the Bosch Smart Home Smoke alarm has been tested and confirmed by the KRIWAN test laboratory.

The Ferion Smoke alarms are not part of the Bosch Smart Home product portfolio.

The product range of Ferion Smoke alarms has been withdrawn from the Bosch Security Systems division offering the product.

Yes. If there is no connection to the Smart Home controller, the Bosch Smart Home Smoke alarm will continue to function as an ordinary smoke alarm and will reliably alert you to fire and smoke. However, information can only be forwarded to the Bosch Smart Home app if there is a connection to the Smart Home controller.

If you have activated the Alarm system service, all connected Bosch Smart Home Smoke alarms emit an acoustic signal. The prerequisite for this is that the "Audible alarm" action is set to the "On" value in the alarm system. To receive a notification, you must be connected to the Internet with your smartphone. You will receive a corresponding notification in your app. In addition, you will receive a push message on your smartphone.

The smart, networked Smoke alarm from Bosch Smart Home alerts you when smoke is detected - and also sounds the alarm loudly when other components in the system report conspicuous events.

Whether you fill the house with guests or leave it empty during your vacation, the networked Smoke alarm from Bosch Smart Home always stays alert. It reports smoke development immediately: on site via siren and on the go, via notification in the app. The Smoke alarm's siren is also used when the Motion detectors or Door/window contacts of your Smart Home system report unusual events. With a loud alarm, it beats uninvited guests into flight. In this way, the Smoke alarm protects your home twice: from fire hazards and intruders.

You can find out more about the Bosch Smart Home Smoke alarm on theProduct page in our Bosch Smart Home Webshop.

Yes, smoke alarms are mandatory in all German federal states. Detailed information on the regulation in the individual federal states can be found at www.rauchmelder-lebensretter.de.

In Austria, almost all federal states have regulations for new, renovated and existing buildings. Often, these regulations even apply to all common rooms in your home.

Different rules may apply in the UK and France.

A Smoke alarm can save lives. There are about 6,000 serious fire injuries every year in Germany alone. About 80% of all fire accidents happen in private homes. About 70% of the affected fire victims are surprised at night while sleeping.

A Smoke alarm detects and reports fire hazards at an early stage and can thus prevent accidents and injuries. The above statistics apply only to Germany and may differ in Austria, the UK and France.

For security reasons, the alarm in the event of a burglary alarm can only be deactivated in the Bosch Smart Home app. This ensures that a burglar cannot deactivate the alarm on his own. So nothing happens if you press the button of an integrated Smart Home Smoke alarm or Twinguard during a burglary alarm.

Smoke alarm should be installed in all living rooms (living room, bedroom, hallways). Other rooms, such as the kitchen, are not suitable. You can find more information in theInstruction manual.

Mount your Smoke alarm centrally in the room. It should be at least 50 cm away from the walls. Roof slopes of up to 20° are also possible. Important rooms are, for example, bedrooms, living rooms and hallways. You can find detailed information on this in theInstallation instructions.

The battery of the Bosch Smart Home Smoke alarm lasts more than 10 years (with typical use, typical storage temperature -5 °C to +30 °C, typical battery temperature -5 °C to +30 °C, and monthly function test). High temperatures above 30 °C shorten the service life.

Additionally, the number of interactions with the device - such as teach-in attempts, resets, alarm tests, frequent triggering of an alarm - can negatively impact battery life.

A non-replaceable 3 V lithium battery is installed in the Smoke alarm. You will be informed in good time via your app and acoustically via the Smoke alarm when the capacity of the battery is about to be exhausted. Then replace the Smoke alarm.

We recommend to replace all Smoke alarms after 10 years of use, because the reliability decreases due to contamination of the system and aging of the components.

The Smoke alarm has a sound pressure level of approx. 87 db(A) for all two alarms, measured at a distance of 3 meters. If you have any questions about the measurement method, please feel free to contact ourCustomer support.

The Bosch Smart Home Smoke alarm works according to the photoelectric scattered light principle. A light source continuously sends light beams into the measuring chamber of the Smoke alarm. Normally, the light beams miss the photocell installed there. However, if smoke particles are in the air, the light beams are scattered and can be detected by the photocell. When a limit value is exceeded, the smoke alarm is triggered.

No, only the Bosch Smart Home Smoke alarm and the Bosch Smart Home Twinguard can be integrated into the Bosch Smart Home system.
