2 Product description
The ekinex® presence sensors EK-DF2-TP and EK-DG2-TP are flush-mount ceiling passive infrared
(PIR) motion detectors, for the detection of movement / presence of people in indoor environments
in order to drive lighting and HVAC systems.
The devices have the same functionality and differ only in the aspects listed below.
Throughout the manual, both devices will be referenced indifferently; the respective different
features will be pointed out wherever required.
The detection area, which has a coverage angle of 360°, can be extended using other sensors
configured as slave devices.
An integratedlight sensor, combinedwith themotion detector, can managelight switching depending
on brightness level as well as presence.
The device has two distinct output channels for lighting, 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 ETS or by means of a dedicated
IR remote during installation.
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
•Semi-automatic or fully automatic operation

5 Switching, display and detection elements
The device is equipped with:
•on the rear side, a programming pushbutton
•visible through the plastic lens, a blue programming LED, a red signalling LED, a PIR sensor,
a brightness sensor and an IR receiver.
6 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.
6.1 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.
6.2 Lighting control channels
The lighting channel has two operation modes, Automatic or Semi-automatic. The automatic mode
controls both switch-on and switch-off; the semi-automatic mode only controls switch-off after a
manual switch-on.
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 the light can be dimmed to alower intensity; if nofurther movement is detected,
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.
6.3 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.
6.4 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.

7 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.
7.1 Positioning for EK-DF2-TP
For the EK-DF2-TP sensor, at a standard mounting height of 2.5 m, presence detection range (for
small movements) is about 4 meters of diameter, while movement detection range (person walking
through the detection area) is about 9 meters of diameter.
The recommended mounting height varies from 2 m up to 5 m.
7.2 Positioning for EK-DG2-TP
For the EK-DG2-TP sensor, at a standard mounting height of 2.5 m, presence detection range (for
small movements) is about 3 meters of diameter, while movement detection range (person walking
through the detection area) is about 12 meters of diameter.

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 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.

8 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.
Cut the supplied shield in such a way to remove the sectors corresponding to the desired detection
area as in following figure:

When the device is installed in place, make sure that the shield is in the correct position according
to the required area masking.
9 Installation
Warning! The electrical connection ofthe device can be carried out only by qualified
personnel. The incorrect installation may result in electric shock or fire. Before
making the electrical connections, make sure the power supply has been turned off.
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.
The device has degree of protection IP20, and is therefore suitable for use in a dry indoor
environment.
The device can be flush mounted through a 65 mm (EK-DF2-TP) / 68 mm (EK-DG2-TP) diameter
hole on a ceiling board with 5 mm to 25 mm thickness.
EK-DF2-TP EK-DG2-TP
For solid ceilings, a plastic barrel-shaped plastic support for external mounting is available as an
accessory.

Warning:
•Do not mount on conductive surface.
•Do not open the enclosure frequently.
•The sensor is a low voltage circuit; never connect it with the 230V line network.
•Do not run the KNX wiring in the same conduit used by line network wiring.
Connect the device to the bus cable terminated by the standard terminal block on the back of the
device. EK-DG2-TP
At this point it is recommended to carry out the commissioning of the device (see “Commissioning”),
or at least the download of the physical address, using the programming button placed close to the
bus connector; alternatively, programming mode can be activated later when the device is already
installed by means of the EK-QR6-IR remote controller.
To insert the device into the hole on the ceiling board, raise and hold the spring clips; guide them
into the hole and gently slide the body of the sensor until it falls into place.
EK-DF2-TP EK-DG2-TP
To remove the sensor, gently pry under the external rim with a screwdriver or another flat object;
once you can get a firm hold with your hands on the rim, pull gently but firmly to extract the body of
the sensor.
