Motion sensor
7 de 23
Adv nced: smoothing
Values From 0 to 10
Description
Is the value that represents the persistence of the detected movement. This value can range
between 0 and 10. The greater value, the more continuous the movement must be for activation
to occur. This value must be lesser than or equal to half the Sampling time parameter.
Recommended values depending on usage:
−Movement detection example: activate lighting): 2.
−Intrusion detection: 8.
Sensitivity
Values From 0 to 100
Description
This is the sensitivity percentage value with which the SRBUS detects movements, i.e., it increases
or decreases the detection area. This value can range between 0 and 100%, where 100% is the
maximum sensitivity.
It is not recommended to enter values over 80%, which could make the SRBUS extremely sensitive
to vibrations in the zone installed) whatever their origin may be.
Recommended values depending on usage:
−Movement detection example: activate lighting): 40-60% lower value for smaller rooms).
−Intruder: 20%.
Adv nced: s mpling time
Values From 0 to 255
Description
This value ranges between 0 and 255, but it is not recommended to be over 64. It represents the
number of samplings taken to evaluate a detection. The greater the value, the slower the device
response it is measured in microcontroller cycles, not seconds).
Recommended values depending on usage:
−Movement detection example: activate lighting): 16.
−Intrusion detection: 64
Adv nced: s tur tion
Values From 0 to 100
Description
Is the value that represents the level of movement with which the device is activated,
independently of the Sampling time and Smoothing. If it is not used, it must be set to 100%.

These parameters allow to configure time delays when enabling or disabling the sensor and the time that the
light is on when the sensor is programmed for lightning control.
Ch nnel dis ble del y
Values From 0 to 65535
Description
The channel keeps detecting motion until the disable delay time set has elapsed.
Ch nnel en ble del y
Values From 0 to 65535
Description
The channel does not respond until the enable delay time set has elapsed.
Ch nnel switch-off del y
Values From 0 to 65535
Description
This parameter is the time between the last motion detection and the sending of switch-off
events. In lightning control, the switch-off delay determines how long after a motion is detected
the light is to be switched off again. With every motion, the sensor is retriggered and the
countdown is re-started, so the light is not switched off until there is no motion within the delay
time

4R ECOMMENDATIONS
4.1 I NSTALLATION
4.1.1 P OSITIONING
The SRKNX could be installed in a false ceiling or behind walls of any non-metalic material. Its hidden installation
ensure safety unwanted intrusions or vandalism to not be accessible.
For longitudinal places like corridors, it is important to place the SRKNX in the correct position. The correct
solution is to place it lengthwise, with the length of the device parallel to the length of the room. Next image
shows the detection directions and the area detection on each one, estimated for place the SRKNX at 2.5m from
the floor.
The detection area placing the SRKNX at 2.5m from the floor) is:
•Guaranteed: 6x3 m.
•Maximum: 12x6m.
These values could change if the SRKNX positioning height changes. The beam detection angle is 140º in
longitudinal direction and 70º in transversal direction.

P ROGRAMMING MANUAL
SRKNX - V2.1
Motion sensor
12 de 23
The best position of the sensor depends on the shape of the room where it is installed, for example a meeting
room with long shape:
The first positioning may cause problems with false detections outside the meeting room or non-detections in
some areas of the room.
The second positioning is the best because the detection area of the sensors fits better with the shape of the
room.

P ROGRAMMING MANUAL
SRKNX - V2.1
Motion sensor
13 de 23
The SRKNX can be partially blinded with metal tape to cancel detection in a zone/direction. For example, when it
has to be installed in one side of the room, it is recommended to reduce the detection area with metal tape in
order to avoid false detections by movements behind the wall.
In addition, the SRKNX must be firm fixed to the surface it will be installed on to avoid false detections and also it
is very important no to install the device in locations susceptible to vibrations or over fluorescents lights for
example.

4.1.2 D ETECTION SIDE
The SRKNX detects by the silk screened side, so it should be placed with this side faced to the movement.
For example, when using the sensor in ceilings, if it is installed with the wrong side faced to the room area it
won’t detect anything or it can detect movements in the upper floor.
4.2 S UPPLY
It is possible to choose between two different options to supply the SRKNX: using an auxiliary power supply
recommended) or through BUS KNX.
4.2.1 S UPPLY USING AN A UXILIARY POWER SUPPLY RECOMMENDED )
The consumption for this option is 30 mA from the auxiliary power supply 12-30Vdc) and 1 mA from the BUS
KNX.
To supply the SRKNX device using an auxiliary power supply, instead of the KNX BUS, the wiring connection
should be:
4.2.2 S UPPLY THROUGH BUS KNX
The consumption for this option is 30 mA from the BUS KNX.
To supply the SRKNX device through BUS KNX, the wiring connection should be:

4.3 A DVANCED CONFIGURATION
4.3.1 S ENSITIVITY
The SRKNX emits a detection beam of high intensity, being of greater or lesser scope depending on the
sensitivity for which it has been programmed from ETS parameters. When the sensitivity is 100%, the detection
range of the sensor covers an area of 12 x 6 m approximately at 2.5 height. If we reduce the sensitivity we will
reduce the detection range proportionally so this parameter must be configured accorded to the size of the
room or area that should be covered.
In the next figure is shown what is the SRKNX behavior depending on the advanced parameters configured:

P ROGRAMMING MANUAL
SRKNX - V2.1
Motion sensor

4.3.2 S MOOTHING AND SAMPLING TIME
The SRKNX is constantly emitting radio frequency signals. The movement detection is based on the change that
any body, material or thing makes in the radio signals reflected. These signals are filtered, processed and
considered as a “motion detection” depending on parameters.
Any movement that generates a number of pulses higher than the smoothing, within a given sampling time, is
considered a “motion detection” by the sensor. For the same sampling time, increasing the smoothing means
that the movement should be faster and higher to generate a “motion detection” because more pulses are
necessary.
The telegrams executed by the sensor when there is a motion detection are sent after every s mpling time, so
increasing the sampling time makes the sensor response slower. If the smoothing does not change, the
movement needed to generate a “motion detection” can be the same, but the sensor does not switch on the
light after the sampling time.
4.3.3 S ATURATION
The s tur tion is the level of reflected signal with which the device considers a “motion detection”,
independently of the sampling time and smoothing. This means that, for a given sampling time and smoothing, if
the signal level received by the sensor is higher than the saturation, it generates a “motion detection” even if
there was not any movement.
