blocked no telegram will be sent neither at the beginning
nor at the end of a detected motion.
Installation Instructions
• The device can be used for permanent installations in
inside or outside areas.
V
The IP55 motion detector (short title AP 251/_1) is a
surface mounted device with integrated KNX interface
for mounting on a wall or ceiling (see figure 1) in inside
or outside areas. It works by passive detection of heat
radiated by bodies in its capture zone. It can be set separately for the beginning and end of detected movements,
whether these are to be reported over the bus and
whether a further telegram is also to be sent. Owing to
its large capture zone of 290°, the motion sensor is also
suitable for mounting on a 90° outside corner. A special
mounting base is available for this purpose as an accessory (5TC7 900 in titanium white and 5TC 901 in anthracite).
By using an infrared remote control which is also available as an accessory (5TC7 902), a user can conveniently
set, by means of the IR receiver incorporated in the motion detector, as well the detector's mode (test mode,
brightness-dependent or brightness-independent mode,
standard mode, pulsed mode) as the brightness threshold and the delay time, independently.
The factory setting of the mode in the as-delivered state
is brightness-dependent motion detection with a brightness threshold of 7 lux and a delay time of 2 minutes.
The detector electronics are powered via the bus voltage.
Application Program
The motion detector AP 251/_1 requires the application
program „25 S1 Motion Detector 909101“ which can be
configured and loaded with the Engineering Tool Software (ETS) from version ETS2 V1.3 upwards.
Via the ETS it can be set separately for the beginning and
end of detected movements, whether these are to be
reported over the bus, whether the telegram “Movement
= On” respectively “Movement = Off” has to be sent only
once or cyclically and whether an additional telegram is
to be sent only once or cyclically. The telegram to be sent
additionally may be a switching command On/Off, an 8bit value (0-255) or a telegram for recalling an 8-bit
scene.
Via a separate communication object the motion detector may be blocked and released if required. If it is

Mounting and wiring
Mounting site
For optimum motion detection, the motion detector
should be mounted sideways on to the direction of motion (see figure 3), as far as possible at a height of 2.5 m,
as far as possible not over but under a luminaire and with
at least 0.5 m separation from any luminaire in the capture zone.
NOTE: The detection range is reduced compared in case
of tangential motion for
- radial motion approx. 30%
- applications in small corridors approx. 75%

Capture zone
In order to avoid unwanted responses from the motion
detector, you must consider potential sources of interference (such as warm air flows, moving bushes or
trees). Unwanted capture zones can be filtered out as
required by fitting the cover screen supplied. It is to be
cut out accordingly for this purpose. The cover screen
fixing ring must not be separated when cutting out seg-

ments (see figure 4). No movements will be captured by
areas of the lens covered by the cover screen.
Figure 7: Mounting the connection box
Figure 4: Adjustment of the cover screen
The capture zone of the detector can also be altered by
turning the lens through some +/- 30° to the right or left.
The capture range can be changed by adjusting the tilting arm (see figure 5).
The bus cable is to be brought in through one of the
punched out openings in the connection box. The insulation of the red and black wire is to be stripped back for
approx. 5 mm, the wires are to be plugged into the part
of the bus terminal with the same colour and the bus
terminal is then to be plugged into its mounting on the
detector's printed connection board.
The detector is then to be plugged into the connection
box and screwed to it with the fixing screw (see figure
8).
Figure 5: Adjusting range of the tilting arm
Mounting and connecting the bus cable
The motion detector's connection box must be correctly
positioned when mounting on a wall (TOP showing, see
figures 6 and 7). You can use the dowels and screws
supplied for this. The spacing of the drilled holes in the
connection box is to be matched on a 60 mm flushmounted socket.
Figure 8: Screwing of the motion detector
Depending on the requirement and the type of mounting, the corresponding condensation opening adjoining
the screw opening is to be punched out (see figures 7
and 9).

Action
Initialising phase
On first applying the bus voltage and after every bus
voltage recovery, the motion detector starts its initialisation phase. For this, the detector output is switched on
approx. 2 seconds. The red LED inside the lens flashes
approx. 3 times per second, until the device enters test
mode automatically after a maximum of 45 seconds.
Test mode
Test mode is a brightness-independent mode with an ON
period of 1 second and an after-run time of 2 seconds. It
can be used for manual checking of the capture zone and
to change the alignment or sensing angle of the lens. At
the end of the test mode period of 10 minutes, the motion sensor switches automatically to the factory setting
(brightness threshold 7 lux, delay time 2 minutes) or to
the individual setting made.
Test mode will be started automatically on first connecting to the bus voltage only after the initialisation phase
has cycled. During any later bus voltage failure, only the
initialisation phase will then be recycled and the motion
sensor then enters the individual setting directly or the
factory setting if no individual setting has been programmed yet.
If test mode is re-activated, then this can be triggered by
holding down S1 and S2 simultaneously for at least 3
seconds (max. 5 seconds). The LED also flashes quickly
for 3 seconds and then stays ON. If you now release the
buttons, then test mode is confirmed by the LED flashing
twice. Test mode can be interrupted prematurely by
tapping S1 or S2 (see figure 2).
Mode and parameter settings
The following table shows the setting options using the
S1 and S2 pushbuttons.
Whereas the detector is switched on for the set delay
time with every motion captured during brightnessindependent operation, during brightness-dependent
operation the detector is switched on with a captured
motion only if the brightness falls below the set switching threshold. If a brightness switching threshold differing from the factory setting is wanted, then the user can
store the current brightness value as the new switching
threshold in the detector's memory by holding S1 down
for a period of less than 3 seconds. When doing this, take
care that the sensor is not covered by the user while
storing the new value.
In pulsed mode, the detector output is switched on for 1
second after the brightness falls below the threshold and
motion is detected. It will then no longer respond to a
movement for 9 seconds.
