• Reliable smoke detection only functions if a suitable installation location is cho-
sen and the smoke detectors are maintained at regular intervals.
• Do not paint over the smoke detector!
½DANGER
Risk of fatal injury from smoke poisoning!
• Smoke fumes are highly poisonous. Just a few breaths result in loss of con-
sciousness and lead to death in a short time!
• In the event of a fire, get yourself and other persons to safety as quickly as pos-
sible.
• Assist children, the elderly and the disabled, in particular.
• Next, alert the fire services as quickly as possible!

Function description
The ARGUS Smoke Detector Single (hereafter called smoke detector) is a battery-oper-
ated smoke detector for private homes in accordance with EN14604 and vfdb14/01.
It promptly detects smoke from smouldering fires and open fires. An intensive acoustic
signal and a flashing LED warn persons of smoke fumes in good time, allowing them to
leave the danger area. The smoke detection works using the light scattering principle
(Tyndall effect). The detector measures the diffusion of beams of light in a smoke cham-
ber. If there is a large proportion of particles in the air due to smoke, the beams are reflect-
ed more strongly and reach a sensor that triggers an alarm.
The smoke detector is supplied with power from a permanently installed battery that has
a service life of at least 10 years in normal use.
The smoke detector continuously monitors the smoke detection function in the smoke
chamber and the battery's voltage. Malfunctions or a weak battery are indicated by acous-
tic signals and LED signals.
The smoke detector also offers various comfort functions.
Hush function
The hush function allows you to manually set smoke detection to be less sensitive for a
specific time. This is useful if you are expecting a lot of smoke or dust and want to avoid
an alarm.
Pressing the function key shortly sets the smoke detector to hush mode for about nine
minutes. This significantly scales up the alarm threshold and the alarm is not triggered.
The LED flashes every 10 seconds during this period.
The smoke detector automatically exits hush mode once the time expires. The normal
monitoring function is active again and the LED flashes as in its normal operating state
again.
Battery failure signal
The permanently installed battery of a smoke detector has a service life of at least 10
years in normal use. The frequency of alarms and the operating conditions have an impact
in the service life.
The battery failure signal begins in good time before the battery life ends (at least 30 days).
The smoke detector then emits a brief warning signal every 45 s. The LED flashes as in its
normal operating state (about every 6 min).
This gives you sufficient time to replace the smoke detector with a new one.
Self-test of smoke detection
The smoke detector carries out a self-test of smoke detection at regular intervals. To do
this, the smoke chamber and evaluation electronics are continuously tested. If an error oc-
curs during this testing, the smoke detector reports the malfunction with an acoustic sig-
nal. The LED flashes as in its normal operating state.
Pollution compensation
The smoke detector recognises that the smoke chamber ages continuously over the
years.
It adjusts the alarm threshold accordingly in order to avoid false alarms due to pollution
and ageing.
However, excessive pollution of the smoke chamber can trigger an alarm.

|Make sure that all persons in the building recognise the smoke detector's signals
in order to identify dangers and behave accordingly.
Make sure that persons in the household with impaired hearing are informed
promptly of an alarm and are able to get to safety.
|In the event of longer absences, you may fail to hear the battery failure signal.
To avoid this risk, perform a function test directly after you return!

½DANGER
Risk of fatal injury from unsuitable installation site!
A poorly chosen installation site can result in late alerting in the event of a fire, or
lead to false alarms.
Always observe the following installation information and the smoke detector's
technical data.
If in doubt, have a certified specialist for smoke detectors perform the installation.
The smoke detector is intended for use in private residential buildings and rooms with a
similar purpose.
The smoke detector is also suitabel for installation in leisure accomodation vehicles
(e.g.caravans).
To ensure optimum protection against fire fumes, the number of smoke detectors in the
building, the choice of installation site and correct commissioning are crucial.
|Smoke detectors must be installed so that the smoke reaches them quickly during
the early stages of a fire.
The smoke detector monitors the specific area around its installation site and not
necessarily other rooms or other floors.

Unsuitable installation sites
• Kitchens that are frequently subject to steam or cooking fumes. Here, additional special
detectors (e.g. heat detectors) should be used.
• In the direct vicinity of open fireplaces or ovens which may occasionally emit smoke.
• Bathrooms that are frequently subject to water vapour.
• Garages that are subject to car exhaust.
• In the direct vicinity of lamps, electronic ballasts, transformers or other electromagnetic
fields that could interfere with the smoke detector's electronics.
• In the direct vicinity of ventilation openings (air conditioning, central ventilation system)
and fans.
• In the direct vincinity of heat sources or direct sunlight.
• Rooms subject to permanently high dust levels (e.g. workshops).
|In the event of high dust levels (e.g. during renovations or rebuilding work), you
should dismount the smoke detector for the duration of the work. Immediately after
the work is complete, reinstall the smoke detector at its original installation site and
perform a function test!
Direct heat radiation (e. g. direct sunlight or vincinity to strong spotlights) can dam-
age the smoke detector and the battery. Choose an installation site with sufficient
distance to strong heat sources.
Minimum and optimum protection
Your flat or home must have a minimum number of smoke detectors to ensure minimum
protection Ain the event of a fire.
At least one smoke detector (depending on the room size) must therefore be installed in
the following rooms:
• All bedrooms
• All children's rooms
• Corridors that serve as escape routes
• Stairwells: top floor
To ensure optimum protection Bin the event of a fire, you should also install smoke
detectors in the following rooms:
• Living rooms
• Attics
• Cellars without permanently high dust levels
• All corridors
• Stairwells: every floor

The smoke detector can only be installed with the mounting base supplied. The supplied
mounting foil with pre-punched drilling holes protects the reverse of the smoke detector
against drilling dust.
For installation, only use the enclosed installation material!
Screwing the smoke detector into the mounting base connects the battery contacts. This
activates the battery and the service life starts. The smoke detector must lock firmly into
place in the mounting base.
If the smoke detector is removed from the mounting base, the battery contacts are discon-
nected and the smoke detector is deactivated immediately.
The battery is permanently installed in the smoke detector and cannot be replaced.
You can use sealing pins (available as accessories) when installing the smoke detector in
order to detect any manipulation or unauthorised disassembly.
Make sure that the smoke detector is aligned correctly when you install it. It should be in-
stalled so that the LED does not disturb anyone in the room when it flashes at regular in-
tervals.
Markings on the smoke detector and mounting base make it easier to align ideally. The
smoke detector can only lock into place in the mounting base and activate once these
markings are aligned after screwing in.
1Align the mounting base. The arrow marking on the mounting base shows the final
position of the LED on the installed smoke detector.
2Attach the mounting foil and mounting base to the ceiling with two screws.
3Press the smoke detector into the mounting base (markings must line up) and turn
clockwise. You should feel the smoke detector lock into place.
4Perform a function test!
Function test
The function test is used to check that the smoke detector's alarm signals are functioning
correctly. The smoke detector checks at regular intervals that smoke detection is function-
ing properly by means of a self-test. Do not use smoke or fire to test the function, simply
use the function key.
Always perform the function test:
• after installation and after each time the device is inserted into the mounting base
• after a longer period of absence (more than 30 days)
• at least once a year.
½CAUTION
Danger of hearing damage from alarm tone!
The function test triggers the smoke detector's loud alarm tone (at least 85 dB(A)).
During operation, remain as far from the smoke detector as possible and also pro-
tect your ears.
|You can only carry out the function test with an activated smoke detector. The
smoke detector must be clipped into the mounting base.

1Press the function key on the smoke detector for at least 1 s.
An alarm tone sounds at short intervals and the LED flashes every 0.5 s for as long as you
hold down the function key. These alarm signals are the same as a real alarm.
|If an alarm is already saved in the smoke detector when the function test is carried
out, pressing the function key first deletes the saved alarm. Then the triggered
alarm tone sounds.
|If the alarm signals do not sound, the battery life has expired or the device is faulty.
In this case, replace the smoke detector without delay.
|By pressing the function key, the smoke detector switches to hush mode for about
nin minutes. The LED flashes every 10 s during this period.
Hush function
1Press the function key briefly.
The smoke detector switches to hush mode for about nine minutes. The LED flashes eve-
ry 10 s during this period.
|In hush mode, smoke detection has only a low sensitivity. Therefore pay extra at-
tention to smoke development in the area of detection and the possible causes. If
large amounts of smoke develop, an alarm sounds out regardless.
You cannot deactivate an existing alarm with the hush function. Therefore, screw
the smoke detector out of the mounting base.
The smoke detector automatically exits hush mode once the time expires. The normal
monitoring function is active again and the LED flashes as in its normal operating state
again.
To guarantee reliable functioning of the smoke detector, you have to check and clean it at
regular intervals, at least once a year.
|It is useful to keep a maintenance log to keep track of maintenance. You should log
the precise installation site, date, any faults you identify and measures you take to
rectify the faults.
If necessary, specify who is responsible for maintenance (e.g. in rented flats). Re-
port any faults you identify to the landlord without delay.
The check includes:
• Checking the installation site (distance to walls, furniture etc., changed use of the room)
• Visual inspection of the smoke detector (identifiable mechanical damage, pollution,
particularly on the outer grille)
• Checking the installation (mounting base attached firmly, smoke detector attached firm-
ly to the mounting base)
• Function test (acoustic and visual alarm signals)
Clean the outside of the smoke detector with a damp cloth at regular intervals and remove
dust with a vacuum cleaner or brush.
Do not clean the smoke detector with compressed air!
|The smoke detector has a service life of 10 years. After the end of service life the
smoke detector must be replaced!
