A reliable infrared movement
detector offers additional
protection. It ensures that
nobody can enter its surveil-
lance zone without activating
the lights. As a result, unin-
vited guests draw attention
to themselves and can be
readily observed.
This acts as a deterrent.
A passive infrared movement
detector registers the move-
ment of a heat source and
switches on the connected
lighting. When the surveil-
lance zone is vacated, the
lighting is switched off again
after a specified delay time.
• The Busch Watchdog is a
passive infrared movement
detector. It registers invis-
ible infrared heat radiation.
• If the registered energy
pattern changes as the
result of movement, a
pulse is activated. The
strength of the pulse
depends on the intensity
of the infrared radiation
and on its direction of
movement.
Introduction Principle of operation
• The Busch Watchdog is
purely a receiver and trans-
mits no signals itself. The
connection between the
heat source and the Busch
Watchdog is the ambient
air. Under certain
circumstances, the recep-
tion conditions are influ-
enced by the prevailing
weather conditions. As
a result of the highly
intelligent electronics,
the Busch Watchdog can
recognise this and largely
compensates for ambient
range fluctuations.
Detection through
obstacles such as glass or
vegetation is not possible.

Corner adapter
With the corner adapter
(order no. 6886), the unit can
be fitted to a house corner.
The detection principle
All bodies with internal heat
emit infrared radiation. The
sensors used in the Busch
Watchdog can detect this
infrared radiation. The more
distinct the radiation in rela-
tion to the surrounding area,
i.e. the colder the outside
temperature, and the more
intensive the radiation of the
detected body, the larger the
sensor signal.
The Busch Watchdog reacts
to large, rapid changes in
temperature. Slow temper-
ature changes and constant
temperatures, such as the
cooling of a car engine, do
not activate the device.
If a person moves directly
towards the sensor, the
increase in heat intensity is
slow, and the unit does not,
therefore, activate imme-
diately. Where possible, the
device should therefore be
fitted at a right angle to the
likely direction of move-
ment to ensure reliable
activation. Humid air (for
example fog) can reflect the
infrared radiation, resulting in
a reduced device sensitivity.

•Sensitivity (E)
The Busch Watchdog has
three sensitivity level
settings. The standard level
is E. The higher level, E+,
is intended, for example,
for indoor applications,
and level E–, has a reduced
sensitivity for a busy
environment (trees or
bushes).
•Dusk setting (N)
Definition of the activity of
the device depending on the
ambient brightness in
operating mode N (0.5 to
1000 lux, daylight mode).
•Test/standard operation
(T/S)
In this operating mode, the
shortest time setting of two
seconds always applies in
the daytime to define the
surveillance zone irrespec-
tive of the set delay time.
After the test phase, the
Watchdog automatically
changes back to the
Standard operating mode.
Connection and settings
The watchdog is connected
with the wall-mounted bracket
and simply screwed onto the
fixing surface. To match the
Busch Watchdog Professional
220/280 and Alarmtech 220
units perfectly to the ambient
conditions, the following
variables are externally
adjustable:
•Operating modes
With the operating mode
selector, the numerous
functions of the Busch
Watchdog Professional
220/280 and Alarmtech 220
can be selected easily and
clearly.
•Time setting
Specifies the delay time
during which the light
remains on after the sur-
veillance zone is vacated.
In addition to the exact time
setting, a short-time pulse
( ), for example for actua-
ting an audible alarm, is
issued.
Principle of operation
The delay time of three
minutes and the light level
of 4 lux are fixed.
•Comfort and
vacation (K-U)
This operating mode
combines the functions of
a movement detector and
those of a conventional
dusk switch. The con-
nected lighting is initially
switched on for 80 minutes
at dusk. Over the next 24
hours, the Busch
Watchdog measures the
ambient light and "learns"
the time of year. The fixed
delay time is then adjusted
accordingly (e.g. extended
in autumn/winter). At the
end of this permanent light
phase, the device reverts
to normal detection.

Principle of operation
•The masking strips
With the masking strips,
areas that are not to be
monitored can be specif-
ically excluded from the
surveillance zone. The
masking strips can also
be used to adjust the sur-
veillance range for distinct
surveillance zones.
The optical system
The range and detection
angle of a movement sensor
are determined mainly by its
optics – i.e. the arrangement
and design of the sensors
used and of the lens.
In the Busch Watchdog
Professional 220, three
highly-sensitive sensors in
combination with a mirror
system and the perfectly
matched lens result in a
detection angle of 220
degrees.
The lens and the mirror
system receive and bundle
the infrared radiation and
project it onto the sensor.
The sensitivity to movement
within the detection zone is
determined mainly by the
number of lens segments
and their optical design. The
available range depends on
the size of the lens segments
(optical magnification) and the
electrical amplification factor.
The lens system of the
Busch Watchdog, which is
permanently connected to
the sensor housing to provide
a good seal for the unit, has
an exceptionally high reso-
lution for movement
detectors.
The possibility of monitoring
"backwards" beyond the
frame without loss of frontal
range, for installation directly
above doors or windows, is
also unique. This is especially
convenient when leaving the
house.
The following factors should
be taken into account at the
planning stage:
• Most frequent direction of
movement of an "object" in
relation to the mounting
location
– Most readily detected is
movement which is
diagonal to the detection
levels (see fig. on p. 6).
• Mounting height of 2.5 m
– This height ensures an
optimum monitoring
function and forms the
basis of the range
specifications.

Principle of operation System
The microprocessor
The use of a microprocessor
to control the Busch
Watchdog provides a series
of valuable features:
• Range stabilisation in
a variety of weather
conditions
• Inadvertent operations
such as movement of
trees,wind, etc. are largely
filtered out
• Dazzleproof e.g. against car
headlights and torches
• Short-time pulse, e.g. for
staircase timer switch
• Precise digital time and
dusk setting
• Selectable comfort and
vacation mode
• Continuous light through
break switch
• Intelligent alarm function
(separate surveillance
zone)

The detection angle
Additional protection for
windows and doors up to the
wall of the house, even in
case of installation directly
above doors and windows,
is provided by the integral
rearfield detection.
With its many mounting
and alignment options, the
Busch Watchdog can be
adapted to suit the optimum
local conditions.

1514
System Special features of the Busch Watchdog
Professional 220/280
The detection range is
affected by the following
factors:
• Installation site and height
• Horizontal and vertical
alignment
• Direction of movement in
the detection zone
• Local weather conditions
The surveillance density
and range
A high surveillance density is
crucial to guarantee the
detection quality of a move-
ment detector. In the Busch
Watchdog, up to 464 closely
packed, large-area switching
segments monitor the sur-
veillance zone in up to 116
sectors. This large number of
operating points guarantees
reliable switching even for
small movements. Its wide
range of up to 16 m at the
front and to both sides is
unique.

In addition to the basic
functions, the Busch
Watchdog Professional offers
numerous advantages in day-
to-day operation.
The various detection
levels
To fully cover the surveillance
zone, the Fresnel lens splits
the zone into several over-
lapping levels.
Level 4 covers the rearfield
detection, which activates
when the front door is
opened from the inside. (for
installation over door frame,
see figure on page 11).
Level 3 covers close-range
detection to prevent unde-
tected entry of the surveil-
lance zone close to the wall.
Levels 1 and 2 cover remote
surveillance and ensure
seamless detection when the
surveillance zone is entered
from the outside.

Range
Special features of the Busch Watchdog
Alarmtech 220
Alarm function
The security provided by the
Busch Watchdog Alarmtech
220 is unsurpassed. The light
gives anyone approaching the
house the impression that
they have been seen. This is
made possible with the
additional security zone. The
range of the security zone is
about six metres to the front
and to both sides.
If someone enters this inner
zone, the red warning light is
activated (can be switched
off with the optional remote
control) and a signal applied
to an additional output, which
can be used, for example, to
activate a second light or
another signalling device.
Remote control
The main functions can be
controlled with a hand-held
infrared remote control unit.
• Light On/Off (for four
hours; then the detector
returns to automatic
mode).
• Automatic On
• Alarm On/Off
(warning light On/Off)
• Comfort/vacation
function On/Off
• Save dusk value

Special features of the Busch Watchdog
Professional 220/280 and Busch Watchdog Alarmtech 220
Automatic range
stabilisation
The range normally fluctuates
between 50 and 100%
depending on the prevailing
ambient conditions.
The Busch Watchdog
recognises the ambient
conditions. A built-in micro-
processor with intelligent
software then controls the
internal amplification to
reduce weather-induced
range fluctuations to a
minimum.
Automatic interference
suppression
This is another feature made
possible by the built-in micro-
processor of the Busch
Watchdog.
External light protection
With the dusk sensor set to
"dark", the Busch Watchdog
could be deactivated by a
light source (torch or car
headlights).
To avoid this situation and
therefore increase security,
the Busch Watchdog leaves
its current monitoring function
unchanged for 90 seconds if
the light conditions suddenly
change.
High-capacity relay
To allow the connection of
high loads without needing
an additional auxiliary relay
high capacity relays have
been used which guarantees
a long service life of the unit.
Test function
To simplify adjustment during
installation, the delay time is
set to two seconds in the
Test position. The dusk
sensor is then disabled.
Once the desired setting has
been found after testing the
settings, select the desired
delay time and the dusk value
to complete the installation.
Self-test
A further advantage of the
microprocessor used in the
Busch Watchdog
Professional 220/280 and
Busch Watchdog Alarmtech
220 is its built-in test
function.
Every time the supply voltage
is connected or a restart
occurs, an internal test pro-
gram carries out a complete
self-test. If this test is
positive, the Busch
Watchdog switches itself on
for at least one minute or the
set delay time. This confirms
that the device is fully
operable.
If, for example, the detector
switches on due to sunlight,
wind and moving branches,
the detection logic recognises
this and suppresses many of
the unwanted operations by
adjusting the operating mode.

2120
Interference factors
Inadvertent operation
The principle of operation of
a passive infrared movement
detector means that its func-
tion depends on the physical
conditions in the detection
zone.
When heat sources move
and the response threshold
of the Busch Watchdog is
exceeded, operation is trig-
gered. Sunlight has a high
percentage of natural infrared
radiation. If the sun shines,
for example, onto a bush or a
tree in the detection zone and
this bush or tree moves in
the wind, this may cause a
movement detector to trigger.
Sunlight reflecting off glass or
water, a heat source cooling
down (e.g. a lamp mounted
nearby) or animals in the
detection zone can also
trigger detection.
Mains voltage peaks, caused,
for example, by switching
inductances such as relays
and contactors on and off,
can also activate a movement
detector. This can be pre-
vented by using surge volt-
age protectors or a special
RC element. For further
information about this, see
the troubleshooting section.
Range fluctuations
In extreme weather condi-
tions, the size of the detec-
tion zone may change. High
outside temperatures and
poor visual conditions due to
fog, rain or snow can tem-
porarily reduce the range.
Excessively long ranges are
caused by close-by sources of
extreme heat, such as lorries
or buses, and at very low
outside temperatures and
good visual conditions. It is
important here to set the
detection range to the
required distance during
installation by adjusting the
angle of the Busch Watchdog
sensor and, if necessary, by
using Busch Watchdog
masking strips.
The automatic range stabil-
isation of the Busch
Watchdog counteracts the
effects described above, but,
for physical reasons, it cannot
guarantee a complete elim-
ination of all unwanted
switching operations under
all conditions.

as a movement of a heat
source in the surveillance
zone.
2. When specifying the
mounting location and
height, take into account
the distances to the road
and to neighbouring
properties etc. to avoid
unwanted triggering.
3. To optimise detection,
install the device at an
angle to the detection
levels. A directly approach-
ing heat source is not
detected as reliably as one
moving across the detec-
tion zone. Since infrared
waves cannot penetrate
solid objects, make sure
that nothing obstructs the
line of vision of the Busch
Watchdog.
4. Every passive infrared
movement detector
responds to a fast change
in local heat radiation. As
all passive infrared move-
ment detectors, To prevent
inadvertent switching
operations, the Busch
Watchdog should therefore
be installed so that it is
protected from rain, wind
and direct sunlight as far
as possible. The housing of
the Busch Watchdog is
adequately protected
against water spray,
allowing an outdoor
installation without addi-
tional water protection.
5. The minimum distance
between the Busch
Watchdog and the
switched lights is 1.5 m.
The temperature change
of a light installed near the
sensor could otherwise
cause the sensor to re-
activate after it has been
switched off.
Spotlights should not be
aimed directly at the Busch
Watchdog.
6.The range to the front can
be adjusted by turning and
tilting the sensor part, and
to the side by partially
covering the lens with
masking strips. If parallel
inductances such as relays,
fluorescent lamps or
transformers are switched
with the Busch Watchdog,
we recommend the use of
an RC suppressor (order
no. 6899) parallel to the
load. As the Busch
Watchdog is an electronic
device, the installation of a
surge arrester parallel to
the power supply is
advisable, since parallel
inductances can cause
overvoltages in the range
of 3000 to 4.000 volts.
2524
Installation
Installation at a
height of 2.5 m
This is the optimum instal-
lation height. The readings
given here (see p. 28 – 29)
were taken at an ambient
temperature of 20 °C with an
approach from the side (for
ambient conditions, see p. 18).
Installation instructions
1. The Busch Watchdog must
be mounted on a solid wall,
since each detector move-
ment has the same effect
2.5 m

2726
7. The adjustment screws
must always point down-
wards after installation,
otherwise the direction of
detection is upwards.
8. Movement detectors are
not suitable as special
burglar alarm systems, as
they do not have the
tamper protection required
for this function.
9. Ceiling installation
The Busch Watchdog
Professional and Alarmtech
units are ideally suited for
installation, for example,
under
– roof overhangs
– canopies
– balconies.
The devices can be pre-
pared for the respective
mounting position by
simply rotating the sensor
housing. Again, the adjust-
ment screws must point
downwards after instal-
lation.
Important:Observe
correct installation height!
(approx. 2.5 m)
10. Installation in lighting
control systems
The detection zone must
be adapted to the local
conditions. For instal-
lation, for example, in
entrance halls and corri-
dors of office buildings,
note that the best results
are obtained with move-
ments across the sur-
veillance zone. To bridge
downtimes, the time
should be set as high as
possible.
