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.
3 Main features
Hidden switch, can fit single round or square wall flush-mounting box
Simple and safe plug-in installation
The presence detector is used to control devices, e.g. lighting and HVAC
Learning function, to configure the device functions by reading the “ambient Lux” parameter
Semi-automatic or fully automatic operation
Evolved lens model, with well-distributed and concentrated detection capabilities: the
detection beams also provide high intensity and sensitivity, so it is possible to detect even a
small shaking movement of the hand
Adjustable sensitivity via ETS®on 4 levels or with "Walk test" to verify detection range
Operating modes: Manual ON / AUTO / OFF
An additional device can be used as slave for any of the channels
Use in the KNX TP bus system (twisted pair) in combination with other KNX devices
Function parameters and settings via ETS®5.0 (Engineering Tool Software) or higher

The sensor is supplied in 2 versions: EK-SN2-TP-GAA, in white color, and EK-SN2-TP-GAE in black
color.
6 Switching, display and detection elements
The device is equipped with 2 switching elements, located under the cover:
a KNX programming button (1)
a switch to select the operating mode Manual / ON / OFF (2)
The following signaling and detection elements are also visible through the lens:
a blue programming LED (3),
a red signaling LED (3),
a PIR sensor, a light sensor and an IR receiver

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.

Increased sensitivity if
movement crosses the lens
beam
Less sensitivity if the
movement is towards the lens

It is recommended to install the device at a height of 1.2 m - 2.0 m. The detection range is 9 m at a
height of 1.2 m - 1.5 m and up to 8 m at a height of 1.8 m - 2.0 m.

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.
