Presence sensor

with 360° detection area

Code: EK-DH4-TP

KNX bus device for movement and presence detection

intended for use in outdoor KNX installations.

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 off depending on the number of

trigger events (movements) detected in a time frame of

conﬁgurable duration.

Main features

• Semi-automatic or fully automatic operation

• Two independent Light control channels

• Two independent HVAC control channels

• One alarm channel

• An additional device can be used as slave for any of

the channels

• Detection span of 360°, sectors can be masked through

optical shields

• Adjustable Sensitivity, with "Walk test" to verify detec-

tion range

• Most parameters can be set from ETS or through an

IR remote

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-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 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 off. 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.
