A reliable infrared movement
detector offers additional
protection. It ensures that
nobody can enter its surveillance zone without activating
the lights. As a result, uninvited guests draw attention
to themselves and can be
readily observed.
This acts as a deterrent.
A passive infrared movement
detector registers the movement of a heat source and
switches on the connected
lighting. When the surveillance 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 invisible 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 transmits no signals itself. The
connection between the
heat source and the Busch
Watchdog is the ambient
air. Under certain
circumstances, the reception conditions are influenced 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 relation 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 temperature 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 immediately. Where possible, the
device should therefore be
fitted at a right angle to the
likely direction of movement 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 irrespective 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 surveillance zone is vacated.
In addition to the exact time
setting, a short-time pulse
( ), for example for actuating 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 connected 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 specifically excluded from the
surveillance zone. The
masking strips can also
be used to adjust the surveillance 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 resolution 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.

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 movement detector. In the Busch
Watchdog, up to 464 closely
packed, large-area switching
segments monitor the surveillance 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 dayto-day operation.
The various detection
levels
To fully cover the surveillance
zone, the Fresnel lens splits
the zone into several overlapping 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 undetected entry of the surveillance 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.

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
