Ekinex EK-DH4-TP User manual

1
Description
The ekinex® presence sensor EK-DH4-TP is a wall- or
ceiling-mount Passive Infrared (PIR) motion detector,
for the detection of movement and presence of people
in outdoor spaces with a coverage area of up to 360°.
The detection area 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 pre-
sence. The device has two distinct output channels for
lighting, with independent parameters; the operation can
be automatic or semi automatic. The device is also capa-
ble of maintaining a constant brightness level by control-
ling 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 o󰀨 depending on the number of
trigger events (movements) detected in a time frame of
configurable duration.

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.
Operation
The sensor reacts to the thermal radiation emitted by mo-
ving 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.
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.
Lighting Channels
The lighting channel has two operation modes, Automa-
tic or Semi-automatic. The automatic mode controls both
switch-on and switch-o󰀨; the semi-automatic mode only
controls switch-o󰀨 after a manual switch-on. The lighting
source can be controlled through two di󰀨erent types of
communication objects: On-O󰀨 switch or Absolute dim-
ming 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 dim-
med to a lower intensity; if no further movement is de-
tected, once stand-by time has expired, the light will be
automatically switched o󰀨. Both the light level threshold
and stand-by time functions can be disabled if not requi-
red.
HVAC Channel
The HVAC channels act in a similar way as the Light Con-
trol channels, but without the standby time and the depen-
dence from the light level.

Positioning
The actual detection range of the sensors depends on
the mounting height. For the EK-DH4-TP sensor, at a
standard mounting height of 2.5 m, presence detection
range (for small movements) is about 10 to 14 meters
of diameter, while movement detection range (person
walking through the detection area) is about 32 meters
of diameter.

Wall mount
i
The optimal range is achieved walking through several
portions of the detection area.
The recommended mounting height varies from 2 m up
to 3 m.
Since the detector responds to temperature change, be
aware that following conditions may cause lower sensi-
tivity:
• 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, espe-
cially 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
reective 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.
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 to limit the detection area as in
following figure. The shield can be cut both in sections
(for radial limitation) and in length (for range diameter
limitation):

When the device is installed in place, make sure that the
shield is in the correct position according to the required
area masking.
Installation
At this point it is recommended to carry out the commis-
sioning of the device (see “Commissioning”), or at least
the download of the physical address, using the program-
ming button placed close to the bus connector; alternati-
vely, programming mode can be activated later when the
device is already installed by means of the EK-QR6-IR
remote controller. Fix the sensor body to the base pla-
te securely through its own mounting screws and finally
adjust the position of the sensor head.

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.
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.
Warning! The sensor is a low voltage circuit; ne-
ver connect it with the 230V line network. Do not
run the KNX wiring in the same conduit used by
line network wiring.
In order to apply the shield, first remove the decorative
bezel from the body. Insert the clip of the shield section on
the edge of the bezel, so that it extends below. Reapply
the bezel making the shield cover part of the lens; the
bezel secures the shield edge against the body.
The device has degree of protection IP55 (Wall mount) /
IP54 (Ceiling mount), and is therefore suitable for use in
an outdoor environment. During the fixing of the base pla-
te, until the wiring is connected and possibly the sensor
is tested for accuracy and correct positioning, the device
can be temporarily mounted by locking it on the baseplate
through a plastic hook. Once all adjustments have been
made, the sensor can be eventually mounted on the base
plate. For application on inner or outer corners, a corner
mounting support is available as an accessory.
Installation procedure - Standard mount
Apply the device body to the base plate by means of the
support hook:
Mount the base plate on the wall / ceiling in the desired
position by means of the supplied screw anchors. Drive
the incoming bus cable through the rubber perforation ca-
ble guides and connect the device.
The sensor head can be adjusted up to 40° downward
and 90° upward, and rotated horizontally max. 90° in ei-
ther direction.

Note. The conguration and commissioning of KNX devices re-
quire specialized skills. To acquire these skills, you should attend
the workshops at KNX cer- tied training centers.
Configuration and commissioning of the device require
the use of the ETS® (Engineering Tool Software) pro-
gram V4 or later releases. These activities must be carri-
ed out according to the design of the building automation
system done by a qualified planner. For the configuration
of the device parameters the corresponding application
program or the whole ekinex® product database must be
loaded in the ETS program. For detailed information on
configuration options, refer to the application manual of
the device available on the website www.ekinex.com.
For the commissioning of the device the following activi-
ties 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; the blue pro-
gramming LED (visible through the device lens) turns
ON;
• download into the device the physical address and the
configuration with the ETS program;
at the end of the download, the operation of the device
automatically returns to normal mode. During the pro-
gramming process, the programming LED is turned o󰀨.
Now the bus device is programmed and ready for use.

IMPORTANT: After a download, it takes approxima-
tely 60 s for the sensor to stabilize before it enters
normal operation mode. During this settling period,
the sensor may not appear to react or perform its
programmed functions.
The programming pushbutton is placed on the rear side
of the device, close to the KNX connector; it is therefore
recommended to program at least the physical address
before the device is installed on the ceiling. Once the
physical address has been assigned, the device confi-
guration can be later downloaded without pressing the
programming pushbutton. If a further activation of the
programming button should become necessary, the devi-
ce can be switched in programming mode through the IR
remote (available separately).
