Movement sensor
with 180° detection area
Code: EK-SM2-TP
KNX bus device for movement and presence detection
in interior rooms. It has to be used in KNX installations
for control of homes and buildings.
Description
The movement sensor ekinex®EK-SM2-TP is a KNX S-
mode device for the detection of movement and presen-
ce of people in interior rooms with an detection area of
180°. The device allows a energetically efcient control
of the lighting and HVAC installations in residential, ofce
and commercial buildings. The device is provided with 3
passive infrared sensors (PIR) that can be separately ac-
tivated and allow an optimal 180° detection. The detection
area can be extended using further sensors EK-SM2-TP
congurated as slave devices. The light intensity for the
constant brightness regulation is measured by the inte-
grated brightness sensor; the value can be furthermore
sent on the bus as a Lux value (2 Byte). The channel
dedicated to the HVAC application allows the indipendent
control of heating, ventilation and air conditioning devi-
ces. The device has an integrated bus communication
module and is realised for wall mounting; the metallic
support allows the mounting on a round or square wall
box with 60 mm distance between the xing holes. The
device is powered by the KNX bus line and requires no
auxiliary power supply.
Operation
The movement sensor reacts to the thermal radiation
emitted by moving bodies. A person who walks in the
detection area automatically activates the lighting. If the
sensor no longer detects any movement, the lighting is
switched off after the time delay set during the congura-
tion with ETS®. If the standby mode is activated, the ligh-
ting remains switched on with a reduced intensity (orien-
tation light function) for the standby time set.

Measurement of brightness
The measurement of the room brightness is carried out
by an integrated light sensor with linear output and optical
lter set on the prole of the human eye. The photoelec-
tric sensor is able to send a 0 or 1 telegram, which indica-
tes a brightness level lower or higher than a programmed
threshold value, independently from the operation mode.
The brightness value, measured in Lux, can be transmit-
ted on the bus.
Lighting channel
The lighting channel has two operation modes that can be
set in the conguration phase:
• fully automatic
• semi-automatic
The fully automatic mode has 3 states: ready, active and
passive. The semi-automatic mode has 2 states: ready
and active. The semi-automatic mode does not switch on
the lighting after the movement detection, but only after
the operation of an external pushbutton.
HVAC channel
The HVAC channel has the same objects and functioning
modes of the lighting function; but the movement detec-
tion is extended, as it is based on the «long duration»
principle. The detection is carried out on several time win-
dows (from 2 to 20) of the same length in each of them at
least one movement has to be detected.
Device completing
For the installation and operation the sensor has to be
completed with the separate order of:
• a lens with cover (see table below);
• a square plate with 55 x 55 mm window;
• a square frame of the form or ank series.
The metallic support, the xing screws and the terminal
block for the connection to the bus line are included in
the delivery.

Actual detection range
The actual detection range of the sensor depends on the
mounting height. The presence (sitting person, small mo-
vements) is detected in a range from 2 to 4 metres, whi-
le the movement (person walking through the detection
area) is detected in a range from 6 to 10 metres. The op-
timal range is achieved walking through several portions
of the detection area.

Note. Programming pushbutton and LED are ac-
cessible from the front side of the device. It is there-
fore possible addressing the device after the sensor
has been mounted on the wall. Once the addres-
sing has been carried out, the device conguration
can be later downloaded without pressing the pro-
gramming pushbutton.

Switching, display and detection elements
The device is equipped with a programming LED and a
programming pushbutton, a signalling LED, three PIR
sensors, and a brightness sensor.
Switching elements
• Pushbutton (7) for switching between the normal and
programming operating modes
Signalling elements
• Red LED (5) for indication of the active operating mode
(on = programming, off = normal operation)
• Green LED (6) for signalling the movement/presence
detection through a blinking
Sensors
• Brightness sensor (4) with linear output for measuring
the light intensity in the room (range: 5 ... 2000 Lux)
• Three passive infrared sensors (1, 2, 3) that can be ac-
tivated individually or in groups. The numbers shown in
the gure correspond to the ones used by the applica-
tion program of the device

Conguration and commissioning
Conguration and commissioning of the device require
the use of the ETS®(Engineering Tool Software) program
V3 or later releases. These activities must be carried out
according to the design of the building automation system
done by a qualied planner.
Conguration
For the conguration of the device parameters the corre-
sponding application program or the whole ekinex®pro-
duct database must be loaded in the ETS program. For
detailed information on conguration options, refer to the
application manual of the device available on the website
www.ekinex.com.
Commissioning
For commissioning the device the following activities are
required:
• make the electrical connections as described above;
• turn on the bus power supply;
• switch the device operation to the programming mode
by pressing the programming pushbutton located on
the front side of the housing. In this mode of operation,
the programming LED is turned on;
• download into the device the physical address and the
conguration with the ETS®program.
At the end of the download the operation of the device
automatically returns to normal mode; in this mode the
programming LED is turned off. Now the bus device is
programmed and ready for use.

KNX
bus
Warning! In order to supply the KNX bus lines use
only KNX bus power supplies (e.g. ekinex EK-AB1-
TP or EK-AG1-TP). The use of other power supplies
can compromise the communication and damage
the devices connected to the bus.
!
Mounting
The device has degree of protection IP20, and is therefo-
re suitable for use in dry interior rooms. The device has to
be installed with the metallic support and the screws (in-
cluded in the delivery) on a wall box with 60 mm distance
between xing holes. Previously connect the bus terminal
block to the bus cable (see: “Connection of the KNX bus
line”) and enter it in its slot on the rear of the device. At
this point it is recommended to carry out the commissio-
ning of the device (see “Commissioning”) or at least the
download of the physical address. Eventually snap the
cover with lens on the device.
Connection of the KNX bus line
The connection of the KNX bus line is made with the ter-
minal block (8) included in delivery and inserted into the
slot of the housing.
Characteristics of the KNX terminal block
• spring clamping of conductors
• 4 seats for conductors for each polarity
• terminal suitable for KNX bus cable with single-wire
conductors and diameter between 0.6 and 0.8 mm
• recommended wire stripping approx. 5 mm
• color codication: red = + (positive) bus conductor,
black = - (negative) bus conductor
Warning! The electrical connection of the device
can be carried out only by qualied personnel. The
incorrect installation may result in electric shock or
re. Before making the electrical connections, make
sure the power supply has been turned off.

Troubleshooting
Error Cause / action
The load does
not switch
- the twilight value is too high
- check the lighting devices
- check the power supply / the protections
The sensor is
activated without
reason / the light
never switches
off
- check if in the detection area there are potential
causes of unjustied activation, such as presence
of pets, heating sources, etc.
- check the distance from the lighting devices
(heating reexion or direct inuence of the light)
- the sensisbility of the sensor is too high; reduce
the sensibility of the detection area (1...10) with
ETS
The light switches
on during the
daytime
- twilight regulation is set to a too high value; set
a lower value with ETS
