8. Functional principle and features
The detector uses the scattered light principle to detect smoke. A light transmitter and light receiver are
both installed in the measurement chamber. Both are separated by an intermediate wall. No optical
connection is made between the transmitter and receiver when no smoke is present in the measurement
chamber. Penetrating smoke disperses the light so that it hits the receiver. This triggers the detector. It
sounds a loud acoustic alarm. The alarm is switched off as soon as the measurement chamber is free of
smoke.

Simple installation
Battery compartment check - the detector can only be fitted to the mounting plate when the battery
is inserted.
9. Behaviour in case of fire
9.1 What should you do if you hear the fire alarm sound from the detector
or from the alarm control panel?
Warning
Leave the premises immediately. Every second counts - there is no time to get dressed or gather
valuable belongings. Use the emergency escape routes.
Warn your fellow residents and make sure they also leave, especially children and people with
impaired hearing.
Do not open doors without first checking the surface. Do not open a door if it is hot or you see
smoke under it. Use an alternative escape route. If the surface is cool, push against it with your
shoulder, open it slightly and be prepared to close it again if there is heat, smoke or fire behind it.
If there is smoke in the air, keep close to the floor and breathe through a damp cloth if possible.
Close the doors after leaving the room.
Once you have left the building, go to the agreed assembly point and do not go back inside.
Call the fire brigade from outside the burning building.
Notify the fire brigade of the situation inside the building.
9.2 What should you do in the event of a false alarm?
False alarms can be triggered by a range of factors, e.g. very high humidity levels, smoke from
cooking or where a lot of dust is created.
If an alarm is triggered, get yourself to safety first of all. Only once you are sure that it is a false
alarm, can you then silence the alarm using the test button. The alarm is also displayed optically
via the LED.
The smoke alarm device resets itself as soon as the smoke particles have moved away from the
smoke chamber inside the detector.

10.2 Learning in
The detector transmits its identity to the receiver either wirelessly or using infrared via the activity LED.
Switch the wireless alarm control panel or the receiver to learning mode. See the relevant receiver
instructions for more details.
Wireless option:
Press and hold the test button for 3 seconds. When the alarm sounds, the detector is sending its identity
by wireless.
Infrared option:
Hold the detector so that the activity LED is positioned over the receiver's IR learning sensor and is
pointing in its direction. Position the activity LED as closely as possible to the IR learning sensor. Press
and hold the test button for 3 seconds. When the alarm sounds, the detector is transmitting its identity in
the IR section of the light to the receiver's learning sensor.
10.3 LED display
If the detector is working properly, the activity LED flashes once every 60 seconds. The detector is not
signalling an alarm.
This flashing can be deactivated using a DIP switch. The DIP switch is located in the battery
compartment, see Fig 4.
a) The activity LED flashes once every 60 seconds during normal operation

11. Selecting the location
11.1 Factors influencing performance
The smoke alarm device can do 3 things:
Detect smoke
Generate an alarm if it has detected smoke
Transmit a radio signal to the receiver if it has detected smoke.
Warning
The environmental conditions around the detector can influence all 3 factors.
Smoke detection
The device is an optical smoke alarm device which works using the scattered light principle. This principle
is most frequently used in smoke detection.
EN 16 EN
Warning
All optical smoke detectors which work in this way have the following problems:
They do not detect radiant heat.
They do not detect heated air.
Other forms of particles can imitate smoke or cause light to be dispersed (e.g. dust, water droplets,
insects or steam)
They are unable to detect smoke if air movement around the detector is restricted.
However, the benefits of optical smoke alarm devices are:
They are robust and reliable.
They do not require large and expensive batteries.
Acoustic alarm
The smoke alarm device uses a piezoelectric sound source, which generates a volume of at least 85 dB
(A) at a distance of 3m from the detector.
The volume of the alarm sound is reduced by:
the distance from the detector
closed doors
thick curtains
locating the detector behind furniture or other objects
Radio signal
The smoke alarm device transmits a radio signal at 868.6625 MHz. This frequency is within the European
harmonised frequency band for alarm signalling. These radio signals are designed for compatible ABUS
alarm control panels and receivers. Radio signals from smoke alarm devices can be absorbed and
EN 17 EN
reflected by metal constructions, wire grating, heat retaining window foils, wiring, metal piping and other
metallic objects.
Electrical devices and other wireless transmitters can also disrupt radio signals.
11.2 Where to locate
Note
Pay attention to all valid fire precaution regulations and recommendations, especially the following
guidelines on the standard use of smoke detectors:
Detailed information is available in the EN 14676 standard “Rauchwarnmelder für Wohnhäuser,
Wohnungen und Räume mit wohnungsähnlicher Nutzung - Einbau, Betrieb und Instandhaltung” (“S moke
alarm devices for use in residential buildings, apartments and rooms with similar purposes – Installation,
use and maintenance”).
Warning
The sense of smell is not active whilst sleeping.
Priority rooms are: living rooms, bedrooms and children’s playrooms.
However, at least one smoke detector should be fitted outside the bedroom.
Due to the especially high risk of fires, entrance halls and corridors with fire loading in certain areas
must be monitored using smoke detectors. Long corridors might require several smoke detectors.
Stairwells are particularly susceptible to fires due to the chimney effect.
In multi-storey buildings, at least one smoke detector should be fitted on each floor.
In buildings with open connections to several floors, at least one smoke detector should be fitted on
the top floor.
To make sure that the detector reliably detects smoke, issues a clearly audible alarm and that a
sufficiently strong signal is transmitted and received by each receiver.
Follow the recommendations below
In order to ensure that the detector can detect smoke:
EN 18 EN
Locate the detector sufficiently high enough in areas where smoke accumulates
For level ceilings, locate it directly on the ceiling in the centre of the room.
For sloping ceilings, locate at least 50cm below the apex
Where the detector cannot be attached to the ceiling, then locate it as high as possible on a wall,
but with a distance of at least 30 cm from the ceiling.
In stairwells locate it on the highest level
When fitting on the ceiling, make sure that the smoke detectors are at least 50cm from the side
walls and 50cm from the corners.
In order to ensure that occupants are able to hear the acoustic signal:
Make sure that the alarm volume is loud enough in the bedrooms to be able to wake up anybody
who is sleeping.
Locate at least one detector on each floor of the house.
In order to ensure that the radio signal can reach the receiver:
Locate the detector high enough
Avoid metal constructions
Attach the detector far enough away from other radio transmitters
EN 19 EN
11.3 Where not to locate
Do not attach the detector in areas w hich smoke will be slow to reach. Avoid “dead” zones. These are
corners between wall and ceiling.
Fig. 5
Avoid the angle at the apex of a steeply sloping ceiling.
EN 20 EN
900mm
Horizontal distance from peak.
Fig. 6
Avoid areas where there is lots of dust. Dust can also collect both on, and inside, the detector. Smoke
might no longer reach the smoke chamber as a result.
Avoid places where draughts can keep smoke away from the detector, such as near windows, doors or
ventilation shafts, ventilators or air conditioners.
Warning
In order to avoid false alarms and malfunctions, do not locate the detector in the following areas:
Places where expected temperature variations are greater than the ambient operating temperature
(-10 °C - +65 °C).
Places where vapour, increased air humidity or exhaust fumes may trigger false alarms, e.g. in
kitchens, bathrooms or garages, in areas with central heating boilers, chimneys, ovens, stoves, ash
trays or toasters.
EN 21 EN
Rooms with lots of vapour and steam, e.g. swimming pools and washing areas. Condensation can
form both on, and inside, the detector.
Areas in which there are a lot of insects, e.g. attic space or greenhouses
Places with a high level of dust or dirt.
Areas where the air can be contaminated with solvent, e.g due to thinner, petrol or turpentine.
External areas. Smoke and foreign bodies can carry over great distances.
11.4 Examples

EN 23 EN
Fig. 9
11.5 Things the detector is not able to do
The smoke alarm device is designed for use in a small house or apartment block, in an apartment or in an
office. The following restrictions apply:
The smoke alarm device is not able to detect a fire if smoke does not reach the smoke chamber.
Smoke from fires in walls, in lofts, on roofs or on other floors will not reach the detector quickly enough in
order to trigger the alarm in sufficient time to allow the occupants to escape without injury.
Smouldering fires are only detected much later because smoke only rises slowly until the flames catch.
If the detector is covered deliberately, then the smoke will not reach the smoke chamber.
EN 24 EN
If an occupant is hard of hearing, sleeping in another room or under the influence of drugs or alcohol, then

they are not able to hear the alarm and are not in a position to react to the alarm.
The detector is not able to warn in a preventative manner. Avoid risks to safety such as smoking in bed,
incorrect storage of flammable materials, overloaded circuits and allowing children to play with matches.
12. Installation
Warning
When marking out the drill holes, make sure there are no electrical wires or cables, pipes or other
important components behind them.
If in doubt, consult an expert before drilling.
Use the mounting plate as a template for marking the positions of the drill holes (see Fig. 10) Pay
attention to the orientation of the markings which are moulded into the mounting plate.
Mark the drill holes and mark two holes for the wall plugs.
During normal operation the detector is silent. When the activity LED is activated (see chapter 10.3 LED
display), it flashes once every 60 seconds.
If smoke is present in the atmosphere, then it can take up to 9 seconds before the device detects the
smoke, goes into alarm status and activates the sounder. The detector transmits a radio signal to the
receiver for every alarm.
If smoke is detected, a loud alarm sounds.
The alarm continues sounding as long as there is smoke in the smoke chamber.
The alarm is only switched off when there is no more smoke in the smoke chamber.
If an alarm stops, always check carefully that no fire is present.
If internal monitoring of the detector reveals an error, then the sounder will beep once every ten seconds,
the activity LED will flash once per second, and the device transmits a radio signal to the receiver.
Remove the old batteries, wait for 30 seconds and insert new batteries. Check, that the activity LED
functions properly.
If, after the batteries are replaced, the sounder continues to beep once every 10 seconds, then the
device has an error. If the device is still under warranty contact the supplier.
13.1 Silencing the alarm
In order to silence the sounder on the smoke alarm device, briefly press the test button once (see Fig 3).
The detector remains silent for six minutes and then reverts back to normal mode. (If you conduct an
alarm test during these six minutes, then the detector reverts back to normal mode after the test.)
EN 26 EN
13.2 Testing
Place the alarm control panel or the receiver into walk test mode See the relevant receiver
instructions for more details.
Press and hold the test button for three seconds (see Fig 3). The sounder will begin to emit the
alarm sound at the end of the three seconds. The detector transmits a radio signal to the alarm
control panel or the receiver.
Check whether the receiver has received the alarm.
Choose another location for the detector if the alarm control panel was not able to receive the
signal.
Complete the walk test at the alarm control panel or at the receiver.
Alternatively, you can use the test spray available from ABUS to test the wireless smoke alarm device.
An alarm will be triggered if the aerosol penetrates the smoke chamber.
Test the smoke alarm device each week, e.g. when doing the cleaning, by pressing the test button.
Always test the detector immediately when returning from holiday, or following an extended period of
absence.
14. Cleaning and maintenance
Never remove the batteries, other than when you want to change them!
When the activity LED is activated (see chapter 10.3 LED display), it flashes once every 60 seconds. This
indicates that the batteries are correctly connected. If the alarm does not sound when checked, the
batteries must be replaced.
The detector will emit a short beep once per minute about one month before the batteries are completely
empty. This signals that the batteries have to be changed. The detector continues to work perfectly
normally during this period. Use high quality batteries such as Duracell MN1500, Eveready Energizer
E91, for example. Always test the detector after changing the batteries.
Note
Wait for 30 seconds after removing the old batteries before inserting the new batteries.
EN 27 EN
The detector should be regularly dusted and cleaned. Clean the detector carefully when you change the
batteries or following a false alarm.
