disposed separately from other household waste. When they
reach their end of life, take them to a designated waste collection
point in your area to guarantee a safe disposal or recycling. Protect
the environment, human health and natural resources!
Alarm silence facility
When the smoke alarm has detected smoke and turns into the alarm
mode, you can mute the alarm for a minimum of 5 minutes and a
maximum 15 minutes by pressing the test panel. After that, the smoke
alarm automatically resets and returns into the normal operation mode.
If there are still particles of combustion in the air, the smoke alarm will
turn into the alarm mode again. WARNING: Use this function only if you
are absolutely sure that the alarm was triggered by a known problem,
e.g. smoke development during cooking.
Low battery mode
When the battery is running low, the smoke alarm will indicate this with
a repetitive beep and flash for approximately 30 days. WARNING: This
smoke alarm is equipped with a non-replaceable battery. When this
warning occurs, replace the device as soon as possible! The acoustic low
battery warning signal can be muted for ten hours by pressing the test
panel. The smoke alarm is still functioning and able to detect smoke
when it's in this mode.
Fault warning mode
The smoke alarm runs through a periodical self-test. When the smoke
sensor is not functioning properly, it will turn into the sensor fault
warning mode. Try cleaning the smoke alarm (see paragraph
“Maintenance”) or replace the smoke alarm!
If the buzzer is not working correctly, the device will turn into the buzzer
fault warning mode. Please immediately contact the manufacturer or
replace the smoke alarm when this occurs.
Night mode
This smoke alarm has an automatic night mode. In dark rooms, the led
signal will be dimmed to prevent disturbance of the night's sleep.

Overview visual & acoustic signals
Maintenance
• This smoke alarm is equipped with a self-testing mechanism. We
recommend to test the smoke detector manually at least once every
three months by using the test facility. If the smoke alarm functions
correctly, it will generate a loud beep. Due to the loudness of the
alarm, make sure that you always stand at arm’s length distance from
the unit when you are testing. If the smoke alarm does not generate
an acoustic signal, the smoke alarm must be replaced immediately!
• Clean the smoke alarm at least once per month to remove dirt, dust or
debris. Use a vacuum cleaner with a soft brush and vacuum all sides
and covers of the smoke alarm. Do not remove the top cover of the
smoke alarm to clean it inside.
• Do not attempt to repair this smoke alarm. If the smoke alarm shows a
damage related to its functionality, it must be replaced!
• Trouble shooting: False alarm is often caused by insect penetration,
dust or steam.
Disassembling
To disassemble the smoke alarm, take a screw driver and push it into the
mounting hole. Then, turn the smoke alarm counterclockwise to remove
it from the mounting bracket.
Thank you for purchasing our smoke alarm!
Before using the device, please read these instructions carefully to

Warnings
• To prevent injury, this device must be securely attached to the
ceiling/wall in accordance with the installation instructions.
• Batteries should not be exposed to excessive heat such as sunshine,
fire or the like.
• Do not paint or cover the smoke alarm.
• In rooms with simple sloped, peaked or gabled ceilings, install smoke
alarms on the ceiling 900mm (3 feet) from the highest point of the
ceiling. “Dead air” at the peak of a ceiling may prevent the smoke
from reaching the alarm in time to provide an early warning.
Where not to install a smoke alarm
• In an environment with a high risk of draught (e.g. close to air
conditioning, fans and ventilation outlets). The movement of air can
impair the penetration of fire smoke into the smoke alarm.
• Areas where fumes or cooking smoke occur, such as kitchens.
• Areas with high humidity such as bathrooms, or close to appliances
such as dish washers or washing machines.
• Areas where dust can accumulate such as the garage or attic.
Mounting
• Place the mounting plate on the desired installation location and mark
where the holes should be drilled.
• Drill two holes with a diameter of 5 millimetres.
• Push the plastic plugs into the holes.
• Insert the screws into the mounting plate, and tighten them firmly into
the plugs.
• Place the smoke alarm on the mounting bracket and secure it by
turning it clockwise.
Activation
Before commissioning the
smoke alarm, it is
important to activate it
and test it for correct
operation.
• When fixing the alarm
body to the bracket the
alarm is automatically
activated.
• Press the full face test
panel and hold it in for
approximately 3
seconds until the alarm
siren sounds. Release
the test panel
immediately a
ft
er this.
The smoke alarm will
generate a beep to
indicate that it's
activated.
Where to install a smoke alarm
• As a minimum, smoke alarms should be located between sleeping
areas and potential sources of fire such as living rooms and kitchens.
In single story homes with one sleeping area, a smoke alarm should be
installed in the hallway, as close as possible to the living
accommodation. To ensure audibility in bedrooms, no smoke alarm
should be further away than 3m from any bedroom door. It may be
necessary to install more than one smoke alarm, particularly if the
hallway is more than 15m long. In single story homes with two
separate sleeping areas, a minimum of two smoke alarms is required,
one outside each sleeping area. In multilevel or split level homes, as a
minimum a smoke alarm should be installed on the ground floor
between the staircase and any rooms in which a fire might start and
on each story in circulation areas which form part of escape route
(normally hallways and landings).
• Additional alarms should be installed in bedrooms in anticipation of
fires originating there, caused by faulty wiring, lights, appliances,
smokers or other hazards.
• For best protection, smoke alarms should be installed in every room in
your home, apart from those listed in the next section. Heat alarms
should be used in kitchens, boiler rooms, laundry rooms, garages and
such like, where smoke alarms would be unsuitable.
• Install smoke alarms in circulation areas at a distance no greater than
7.5m from the farthest wall, no greater than 7.5m from a door to any
room in which a fire might start and no greater than 7.5m from the
next smoke alarm.
• As it is impossible to predict the source of a fire, the best location for
an alarm is usually the center of a room or hallway. If it is necessary to
place a smoke alarm on a wall, always locate the detection element of
the alarm 150mm to 300mm (6 to 12 inches) below the ceiling and the
bottom of the alarm above the level of doors and other openings.
