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,
The Bosch Smart Home team

1.0 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 trigger
a notification is forwarded to your
phone.
The forwarding of alarms to connected Twinguards and mobile
devices will only work when the gateway is switched on and connected
to the internet.
Without the smoke alarm gateway you are not able to link multiple
smoke alarms.
The Gateway must be set up before the smoke alarms!

6.0 MOUNTING THE TWINGUARD
6.1 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 the maximum effectiveness we recommend that additional
smoke alarms should be installed in living areas, attics and basements.

28 29
The Smoke Alarm should be mounted on the ceiling, its 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 (maxi-
mum 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 that 7.5 m
from a smoke alarm and the end of
the hallway. We recommend that a
smoke alarm is installed at all hall-
way 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 that
0.2 m, we recommend that multiple
Smoke Alarms are fitted if the ceiling
area created by the beams is greater
than 36 m2
> 20°> 20°

When choosing a mounting location and when drilling, pay attention
to potential electrical cables and/or supply lines that could be behind
the wall.
In order to prevent injury, the mounting instructions in this instruction
manual must be followed and the general safety regulations observed.
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.
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.

32 33
6.2 Fixing with screws
▶ 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
▶ Now fit the Smoke Alarm to the
mounting bracket, align and rotate
in the direction of the arrows
▶ When you hear a “Click” your
Twinguard is mounted correctly

7.0 MAINTENANCE INSTRUCTIONS 7.1 Visual inspection
We recommend you inspect and test your Twinguard
on a monthly basis.
▶ The smoke inlet openings along
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

36 37
▶ To do this, briefly press the oper-
ating 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 success-
ful, 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. It initiated or muted using
the APP, detection remains active.
7.2 Functional test
We recommend that you test your Twinguard immediately following
installation and every month following that. It should also be checked
following every battery change and software update.
If the signals described do not appear, the Smoke Alarm is faulty:
Please replace the product in this case.
Always press the Smoke Alarm’s operating button in the center at
the height of the Bosch logo.
