Product Guide
The EBDHS-KNX PIR (passive infrared) presence detector
provides automatic control of lighting loads with optional
manual control. The EBDHS-KNX is a high sensitivity PIR
detector suitable for high bay applications, such as
warehouses and factories, and where high detection
sensitivity is needed. The device is designed to be part of a
KNX system.
Features include.
All functionality is fully programmable using the KNX ETS
commissioning software.
PIR Sensor
Detects movement within the unit's detection range,
allowing load control in response to changes in occupancy.
IR Receiver
Receives control and programming commands from an
IR (infrared) handset.
Light Level Sensor
Measures the overall light level in the detection area
Status LEDs

KNX Programming LED
The LED lights when the device is placed in programming
mode via the button or IR remote. In programming mode,
the Status LED will mimic the programming LED (i.e. will be
on for the duration of programming mode).
KNX
KNX Programming Mode Button
Communication
LED
Press to signal to the KNX network to enable the system to
discover the device. This can also be done via IR.
KNX
Switch Input Connector
Program
Two inputs can be used to perform several configurable
Button
functions, for example, dim up / down, scene recall and
also contribute to logic functions.
KNX
Connector
Two switch inputs to manually override the dimming
levels and / or override the lights on or off.
KNX programming mode accessible with IR handset
and also by using the push switch on the back of the
unit.
Programmable logic block. This allows conditions to
be set. For example: send the occupancy telegram
only if the switch is pressed and the lux is low.
Full scene selection functionality selectable via the
IR handset (UHS7 ), eg: scene, on, off, raise and
lower .

These correspond to the 4 outer passive infrared sensors under the lens. Use these marks to align with aisles and corridors to...
  • Page 3 Applications Masking The EBDHS-DD includes two clip-on masking shields to allow for precise masking of the detection shape. The masks can be easily shaped to produce detection patterns suitable for applications such as aisles and corners and for narrowing the detection diameter. Lateral tear pattern for making a ‘slot’...
  • Page 4 Installation Choosing a Suitable Location The EBDHS-DD is designed to be ceiling mounted and must satisfy the following criteria:  Avoid positioning the unit where direct sunlight may enter the sensor element.  Do not site the sensor within 1m of any lighting, forced air heating or ventilation. ...

The bus voltage should be approximately 30V.  Check that the programming LED illuminates when the button is pressed on the rear of the unit. What if the lighting does not turn ON? ...
  • Page 6 KNX function and configuration Introduction A presence detector monitors the detection zone for occupancy, and causes one or more actions to be executed when a person enters the detection area. In their simplest form, presence detectors could be used to turn on a light when a person enters a room, and to turn it off again after the person leaves.
  • Page 7 KNX function and configuration Configuration Configuration of the presence detector and associated logic functions is via the ETS tool, available from the KNX association. Start the process by downloading the device catalogue from the www.cpelectronics.co.uk and importing it into ETS. Once imported, the device can be added to a project and assigned an individual address in the normal way. The detector is configured via the Parameters tab, and all options are grouped by function as previously described.
  • Page 8 KNX function and configuration General parameters & group address table Setting Options Description Sensor walk test LED Disable Enable or disable the sensor walk test LED, triggered Enable when movement is detected. This is useful for commissioning, (or if the detector is to be used in bedrooms).
  • Page 9 Switch inputs The switch inputs parameters are used to define the behaviour when the two volt-free switch inputs are connected. The inputs can be used to send dimming commands, recall scenes or send simple switch (on/off) telegrams. It should be noted that these switch inputs can be used as part of logic functions if required.
  • Page 10 Infra-red scene control The infra-red scene control parameters are used to configure the scene recall behaviour when the sensor is used with the UHS7 remote control handset. This handset provides eight scene recall buttons, dim up/down buttons and on/off buttons. As KNX defines a maximum of 64 scenes per group object, the parameter page allows these scenes to be mapped to the 8 remote control buttons.
  • Page 11 Logic controller 1 / 2 (switch/scene) The switch/scene logic controller tabs allow up to two independent switch/scene recall channels to be configured. Each channel receives the same inputs from the movement sensor and Switch input connections, but have separate KNX group objects.
  • Page 12 Logic controller 3 (brightness) The brightness logic controller aims to maintain a uniform brightness in the sensor area at all times. Two brightness targets can be defined, subject to a successful calibration (as detailed earlier). In similar fashion to the movement controllers, a logic expression can be constructed to choose which brightness target the controller should try to achieve.
