2 Product description
The ekinex®EK-SN2-TP sensor is a passive infrared (PIR) indoor presence detector based on KNX
standard, with movement function and wall switch. It is designed for the detection of movement /
presence of people in shops, offices, small rooms, residential areas such as corridors, stairs,
bedrooms, etc., in order to drive lighting and HVAC systems.
The detection area has a coverage angle of 200° and it can be extended using other sensors
configured as slave devices. An integrated light sensor, combined with the motion detector, can
manage light switching depending on brightness level as well as presence.
The device has two distinct output channels for lighting control, with independent parameters; the
operation can be automatic or semi automatic.
The device is also capable of maintaining a constant brightness level in the room by controlling a
dimmable light source.
All of the above parameters can be set by the user either through KNX ETS®software.
The device has two additional HVAC channels, which act in a similar way as the Light Control
channels but without the standby time and light level dependence.
An additional alarm channel can switch the load on or off depending on the number of trigger events
(movements) detected in a time frame of configurable duration.

7 Operation
The sensor reacts to the thermal radiation emitted by moving bodies; the detection area is optically
divided in small sections through a composite lens. A person walking in the detection area across
the sections triggers the sensor.
7.1 Brightness measurement
The measurement of the room brightness is carried out by an integrated light sensor with linear
output and optical filter set on the profile of the human eye. The brightness value, measured in Lux,
can be transmitted on the bus.
7.2 Lighting control channels
The lighting channel has two operation modes, Automatic or Semi-automatic. The automatic mode
controls both switch-on and switch-off, when a movement is detected; the semi-automatic mode
requires manual switch-on, which is maintained until movement is detected; it will swich-off only
when no more movement is detected.
The lighting source can be controlled through two different types of communication objects: On-Off
switch or Absolute dimming percentage.
In automatic mode, a load connected to a lighting channel will be switched on when movement is
detected and (if desired) the ambient light level is below a preset brightness value.
When no movement has been detected for a programmable time duration, a stand-by phase can be
entered, during which thelight can bedimmed to alower intensity;if nofurther movement isdetected,
once stand-by time has expired, the light will be automatically switched off.
Both the light level threshold and stand-by time functions can be disabled if not required.
7.3 Constant ambient brightness regulation
The internal brightness sensor can be used to maintain a constant ambient brightness if a dimmable
light source is available. The light source must be capable of being controlled through a Relative
dimming communication object.
7.4 HVAC control channels
The HVAC channels act in a similar way as the Light Control channels, but without the standby time
and the dependence from the light level.
8 Positioning
The actual detection range of the sensors depends on the mounting height.
The optimal range is achieved walking through several portions of the detection area.

Since the detector responds to temperature change, be aware that following conditions may
cause lower sensitivity:
In very foggy days, the sensitivity may be less due to moisture collecting on
the lens.
In very hot days, the sensitivity may be less since high ambient temperature
is close to body temperature.
In very cold days when heavy clothing is worn, especially if the facial area is
covered, very little heat will be emitted from the body causing the unit to be
less sensitive.
Please also verify the following conditions during installation:
Avoid pointing the detector toward objects with highly reflective surfaces,
such as mirrors, glass, etc.
Avoid mounting the detector very close to heat sources, such as heating
vents, air conditioners, lights, etc.
Avoid pointing the detector toward objects which may sway in air currents,
such as curtains, tall plants, etc.
9 Limitation of the detection area
The detection area can be limited, in order to avoid unwanted activations, by means of the supplied
optical shielding filters. The shield consists of three layers, each divided into four units, capable of
masking an angle of approx. 50 ° each.
Figure 5 - Lens shield with layers
When mounting the device at a height of 1.2 m - 1.5 m, the detection range is:
Layer A: masks the area with a circle from about 0m to 9m.
Layer B: masks the area with a circle from about 0m to 3m.

IMPORTANT:
After a download, it takes approximately 60 s for the sensor to stabilize before it enters
normal operation mode.
Both the light output channels and the red LED are steady ON during the warm-up
phase, and they are switched OFF at the end.
During this settling period, the sensor may not appear to reactor perform itsprogrammed
functions.
13 Operations
13.1 Slide switch setup
By using a screwdriver in the center groove (1), pull out the cover of slide switch slightly (2).
Turn it upwards to access the switch (3).
Once the setting is complete, turn the cover downwards in its original position.
Figure 13 - Slide switch access
13.2 Slide switch functions
The slide switch allows to set the following parameters.
AUTO: by placing the switch in the central position, the detector is in AUTO mode.
ON: In ON mode, the load remains ON for 8 hours and the LED flashes for 1 second every
5 seconds. After 8 hours, the detector automatically returns to AUTO mode.
OFF: in the OFF position, the load remains OFF for 8 hours and the LED flashes for 1 second
every 5 seconds. After 8 hours, the detector automatically returns to AUTO mode.
In the event of a power failure, the detector enters AUTO mode once the power is supplied again,
even the switch is set to ON or OFF.

13.3 Walk test
The purpose of the walk test is to select a proper location and verify the desired detection coverage.
Lux setting value is not regarded during this process.
First of all, make sure the tester is within the detection coverage and the sensor is connected to the
powered KNX bus and allow the 60 s warm-up time to pass. During this timeframe, the red LED
turns on, then turns off after warming up time is expired.
Set the operating mode to “Test” via ETS®, then refer to the following steps:
Walk from outside across to the detection pattern until red LED and load turn on for approx. 2s, then turn off again. The
2s, then turn off again. The next trigger should be after 2s (please refer to
Figure 15).
If required, adjust the sensitivity setting through ETS®.
Also if required, adjust the time setting through ETS®.
Repeat the procedure in other selected radial directions, particularly if a shield is applied on
the lens.
Repeat the above steps until desired performance is achieved.

13.4 Auto / Semi-auto mode (absence detection function)
This function is enabled with ETS®setting and it is used to activate / deactivate Auto mode or Semi-
auto mode of Light control output C1.
The behaviour is as follows:
Under auto mode, the load will turn on automatically when a movement is detected and the
ambient light level is below the Lux setting value. When movement is no longer detected and
the delay time has expired, the load will turn off automatically.
Under semi-auto mode, the load can only be manually switched on by operating via a
connected external pushbutton. When the load is switched on, it will keep be on if the
movements are detected constantly. The load will turn off only when movement is no longer
detected and the delay time has expired.
Please refer to section 14.3 for further information.
13.5 Test mode
Parameters can be set via ETS®. Test mode switches to the RUN status after “storing”, or 10 min
after activating the test mode. Load and red LED are not controlled by Lux setting under the Test
mode. Once the detector is triggered, both load and red LED turn on for 2s, then turn off, and the
next triggering should be 2 sec interval.
IMPORTANT:
The settings of functions described in paragraphs 13.6, 13.7, 13.8, 13.9 and 13.10 are
intended for lighting control, therefore do not apply to HVAC control.
13.6 Manual ON / OFF and DIM switching function
This function is enabled with ETS®setting and operated either by the slide switch loacted under the
frontal cover, or through a connected KNX interface module on KNX bus system.
Please refer to section “Parameter setting“ - “Communication objects description“ for further
information.
13.7 Master / Slave selection
This function can only be set via ETS®software and it allows to set the device as a master or slave
device:
when detector is enabled as master device, all the functions are available and it also can
receive the triggering signal from one or more slave detectors;
if it is enabled as slave detector, then it works exclusively to extend the field of detection and
all its function are managed by a master detector.
Please refer to section “Parameter setting“ - “Communication objects description“ for further
information.
13.8 Ambient light appraisal
In case of changeable ambient light level, the detector can postpone delay time of turning on and off
loads, in order to avoid its unnecessary on or off switching.
This behaviour works in two ways:
The ambient light level changes from bright to dark: to avoid unnecessary switching on / off
of the load due to temporary variations in the ambient light value caused by events (e.g.
i

Application manual

passing cloud), the detector has been designed with a delay of 10 s for light activation, i.e. it
will ignore any movement within the 10 s delay time. The red LED will be on steady as an
indication, but the detector will not react within this timeframe.
The ambient light level changes from dark to bright: if the ambient light level exceeds the
“Switch ON Lux value”for 5 min, there are different reactions according to the value of the
“Lighting delay time” parameter:
oIf Lighting delay time > 5 min: the light will be automatically switched off after 5 min.
oif Lighting delay time < 5 min:the light will be automaticallyswitched off when the set time
expires, if no movement is detected within the 5 min. timeframe. But if any movement is
detected within the 5 min timeframe, the time will be reset upon detection and the light is
switched off after 5 min.
13.9 2-level (Standby Lighting) function
In Auto mode and when Output type is set to “Dimming”, when the ambient light level falls below the
pre-set “Switch ON Lux value”, the detector will enter into 2-level mode function automatically.
if “StandbyTime” is set to “Infinity”,the detector will enter into 2-level mode when the “Lighting
delay time” is expired. In this situation, if a movement is detected, the load will turn on with
the setting illumination (100% or the dimmed value according to the setting of “Standby
brightness) and then turn off if movement is no longer detected and the “Lighting Delay time”
has expired. It will be cycled until the ambient light level is higher than the “Switch ON Lux
value”and it lasts for 5min, then turns off and the detector resumes to Auto mode function.
if “Standby Time” is set to other position except for “infinity”, the detector behaviour is
basically the same as above mentioned, but the duration is according to the selected
“Standby Time” value.
If “Lighting standby time” is set to “disable” (OFF), the load willbe off when the “Lighting delay
time”is expired.
13.10Constant light control
According to the changeable ambient light level, if “Constant light control” is set to Enabled, then the
load can dim to bright or dark automatically to match the “Preset setpoint” Lux value.
13.11Alarm
The alarm function can be set to behave in the same way in case of switching on or off, or in a
different way depending on the event.
The Alarm output (Communication Object 18) can be locked using CO 17 (Lock alarm).
Options for “Behaviour at switching ON (or OFF) lock by CO are “no reaction”, “switch OFF” and
“switch ON”.
The number of detected movements (“windows”) within a time frame (“Duration”) can be set.
