Frequently Asked Questions - Swiss Garde 300 KNX Niko

How to install the Swiss Garde 300 KNX detector?

The detector must be flush-mounted into the ceiling by a qualified electrician. Connect it to the KNX bus (24 V). Use ETS software to configure it (download the application from the Niko website). Observe the flush mounting dimensions (90x90 mm).

What is the maximum detection range?

The range is up to 300 m² with a 360° angle. The optimal mounting height is 2.5 to 4 metres. The sensitivity of the three PIR sensors (1 to 10) is adjustable in ETS.

How to set the brightness threshold for detection?

In ETS software, go to the Light menu then Brightness threshold below which the detector is active. Set a value from 10 to 2000 lux or choose always for light-independent detection.

What to do if the detector does not detect correctly?

Check that the PIR sensors are not obstructed and that the sensitivity is sufficient (setting in ETS from 1 to 10). Make sure the detector is not in slave or locked mode. Check the bus power supply and the configuration of the communication objects.

How to connect a slave detector to the master?

Set the slave detector to Slave mode in the general settings. Link the output object (object 0) of the slave to the input object (object 2) of the master in ETS. The slave sends the detection to the master.

What is constant light regulation?

This function maintains the ambient brightness at a target value (e.g. 300 lux) by adjusting the dimming of the luminaires. It uses two channels to control two groups of luminaires with a possible offset (offset from -50% to +50%). Activate it in ETS via the Constant light regulation menu.

How to calibrate the brightness measurement?

Measure the actual brightness with a luxmeter at the detector location. Read the AD calibration value (object 10) in ETS. Enter both values in the Brightness value calibration menu for precise adjustment.

Can I use the HVAC channel for a presence alarm?

Yes, the HVAC channel is independent of brightness and can serve as a presence indication. Set the number of observation windows (1 to 32) and the duration (1 s to 30000 s). For a fast response, use 1 window of 1 s.

How to reset the detector?

To restore factory settings, reprogram the detector with the factory application in ETS. A bus outage (24 V) for more than 10 seconds may also cause a restart, but the parameters remain in non-volatile memory.

What are the essential communication objects?

The main objects are: object 0 (light output), object 1 (external command), object 2 (external motion input), object 3 (forced control/lock), object 4 (HVAC output), object 9 (brightness value in lux), object 16 (constant regulation ON/OFF), objects 22 and 23 (dimming outputs channels 1 and 2).

3.8. Constant light parameters

Constant light controller This parameter enables or disables the constant light controller.
Channel 2 for constant light control Channel 2 can be enabled for constant light controlActive/inactive Via the output object 23 a configurable value with a fixed offset can be transmitted
Preset setpoint	The preset setpoint in lux for constant light control can be preset in the ETS. It can also be changed via objects 17 and 18 (constant light - dimming relative and constant light - dim completely).
Transmit difference	This parameter (from 1% to 100%) defines the tolerance window to be exceeded in order to send a new brightness control value.
Switching constant light control with	Switching constant light control ON/OFF can be done using three different sources:By → object 16, presence detection on the light channel or presence detection on the HVAC channel.
Time interval for cyclical transmission	Defines the cycle time interval with which the last brightness value is repeated, even if it has not exceeded the tolerance window.Cyclical transmission can also be disabled.
Switch on brightness value The switch on value for the lighting can be set from 1% to 100%.
Switch on timeout This parameter defines the initial time delay before constant light control is started.
Offset for channel 2 * The offset range for channel 2 can be set from -50%, 0% to +50%.
Force control during switch-on	This parameter allows the constant light controller function to be set to: no reaction, minimum brightness, maximum brightness
Force control during switch-off	This parameter allows the constant light controller function to be set to: no reaction, minimum brightness, maximum brightness
Time for relative dimming	This parameter allows the relative dimming time to be set. This will influence the dimming soft control.
Take over set point after	This parameter allows setting the time delay after which a new setpoint will be recognized and stored in the RAM memory.
Changed setpoint to flash memory	This parameter allows a new set point to be written to the flash memory.
Keep changed set point	Here at Yes the changed value is stored in the RAM.Attention: now corresponds to the new nominal value of the last new dimmed brightness!
Scene	Various lux values can be set as light scenes (light moods). These can be enabled through object 21 as well.
Dead zone	The dead zone is an area within which the actual light value can change without generating new control commands. The default value for the dead zone is 2.The lux value tolerance of the dead zone can be extracted from the table below.Example:Dead zone value = 2Brightness = 500 luxThe resulting tolerance is: +/- 24 luxThis means that the actual value can change from 476 lux to 524 lux without sending new control inputs to the actuator.

In addition to the previous constant light control channel 1 (Object 22 ) there is a second constant light control channel 2 (Object 23 ). The control signal of channel 1 ± offset value is sent to the dimming actuator for light channel 2. Internally, the control range has been extended to ± 150% in order to maintain a reasonable control range at the limits.

That means: Offset at -50%, darkness: FF (=100%) is sent to both objects. Internally, object 1 is at 150% and object 2 at 100%. If the ambient brightness now increases, object 1 remains at 100% (150% - x) and object 2 is regulated downwards (150% - 50% - x). If the regulation now drops below 100%, object 1 will also be visibly smaller on the bus, e.g. 73%, object 2 23%. Object 1 is then regulated down to 0 and object 2 is set to the minimum value of 50%. The values for transmission difference and cyclical transmission are taken from the once off available parameters.

4. FUNCTIONAL BLOCKS

The functionality of the presence detector can be split up into the following blocks:

• Motion detection
• Brightness measuring
  • Light control channel Switching
  • Light control channel preset dimming with optional standby light function
  • HVAC control channel (with presence function)
  • Lighting dependent threshold switch
  • 2 channel constant light control

The motion detector and the brightness sensor (lux) each work independently on the light channel and the HVAC channel.

The constant light controller receives the actual brightness value from the Lux sensor. The controller can

be switched on/off by a command via → object 16 or triggered by motion detection on the light or HVAC channel.

After switching or recovery of the KNX bus voltage, the presence detector usually generates a switch-on procedure.

4.1. Light control channel

The light control channel has two operating modes that can be selected via the detector operating mode parameters.

The possible settings are:

• fully-automatic
• semi-automatic

The differences between the fully-automatic and semi-automatic modes are:

• fully-automatic mode has three operating conditions: ready, active and passive
• semi-automatic mode has two operating conditions: ready and active
• semi-automatic mode does not switch the light on after motion has been detected.

Lighting can only be switched on manually by an external KNX switch.

4.1.1. OBJECT 0 OUTPUT - LIGHT - SWITCH

← Output 1 bit

After each detected motion this output sends an "ON" command and starts the delay timer

The delay time can be set with parameter delay time from 1 second to 4 hours.

At the end of the programmed time interval an "OFF" command is sent to the output (object 0).

4.1.2. OBJECT 0 OUTPUT - LIGHT - COMPLETE DIMMING

← Output 1 byte

This mode sends preselected dim values (0% to 100%) to the output for objective value for ON and for objective value for OFF respectively.

4.1.3. OBJECT O OUTPUT - LIGHT - SCENE

← Output 1 byte

For the Objective value for ON or Objective value for OFF one of 32 scenes can be selected respectively.

4.1.4. OBJECT 1 EXTERNAL SWITCHING / STATUS - LIGHT - SWITCH

→ Input 1 Bit

Input object 1 external switch / status can be used in two different ways:

• As an input for an external push button that directly switches on the light
• As an input for monitoring the status or the input of an actuator

In both cases, a received telegram „ON“ sets the detector to the ON state and an „OFF“ telegram to the ready state.

Whether commands for ON or OFF will be sent during the transitions depends on the parameter sending conditions for external push button.

After having received an ON command, the follow up timer starts as if a motion had been detected.

Lighting is subsequently switched off again.

After having received an OFF command the detector remains in its passive status during which it will not detect any motion. After having passed the idle time after switch off, the detector is ready again.

The idle time after switch off can be programmed in the light menu.

4.1.5. OBJECT 2 EXTERNAL MOVEMENT - LIGHT - SWITCH

→ Input 1 Bit

Additional detectors (slaves) can be connected through Object 2 "external movement - light - switching".

The received signal from external presence detectors is processed the same as if from its own detector and works in parallel.

Object 2 is used to set up a Master-Slave configuration as follows:

Slave devices: Connect all outputs of the slave devices (←object 0) to the input external movement-light-switching (-object 2) of the master device.

4.1.6. OBJECT 3 INPUT - LIGHT - FORCED CONTROL / LOCK

→ Input 2 Bit

The meaning of this object is defined by the Light - focused control object or disabling object parameter.

Forced control object:

Object 3 when used as forced control object has 3 values which can be received by a 2 bit command:

1. Forced control object ON (control = 1, value = 1)

An ON command is sent unconditionally to the output – light (object 0).

The follow up timer is disabled and the timer release time starts.

If after having terminated the release time and no further command is sent to the forced control object, normal operation is resumed.

1. Forced control object OFF (control = 1, value = 0)

An OFF command is sent unconditionally to the output - light (object 0).

The delay timer is disabled and the timer release time starts.

If after having terminated the release time and no further command is sent to the forced control object, normal operation is resumed.

1. Forced control object auto (control = 0, value = 0)

Normal operation is resumed immediately.

Locked object:

Object 3 when used as locked object has 2 values which can be received by a 1 bit command 0 and 1:

The response to a switch command on this object is controlled by two more parameters:

Light → if locked object = 0, and Light → if locked object = 1,

Both parameters can specify one of the following commands:

• forced control ON
• forced control OFF
• automatic
• lock (actual state)
• do nothing

Note: Incorrect settings of parameters such as: locked object, lock at 0 and no action at 1 and release time restraint OFF can completely inactivate the correct function of the presence detector.

4.2. HVAC channel

← Output 1 bit

The HVAC channel has the same objects and the same operating modes as the light channel. It works the same way as the light channel as well.

The motion detection function, however, has been expanded and substituted by a "longer presence detection". This is done by setting several equally long monitoring time windows. At least one motion detection must occur during each time slot.

The parameters are:

• number of monitoring time windows

• length of monitoring time window (s)

Presence function

The HVAC output can be used as a presence detection. To activate this, the number of observation time windows must be set to 1 and the length of the observation time window set to 1 second. The presence signal is independent of the ambient light level.

4.2.1. OBJECT 4 OUTPUT - HVAC - SWITCH

← Output 1 bit

Object 4 "Output - HVAC - Switch" is similar to object 0 "Output - light - switch" but has additional functions (see HVAC parameters, page 10).

4.2.2. OBJECT 5 EXTERNAL SWITCHING / STATUS - HVAC

→ Input 1 Bit

Object 5 "External switching / status - HVAC" is identical to object 1 "External switching / status - light".

4.2.3. OBJECT 6 EXTERNAL MOVEMENT - HVAC

→ Input 1 Bit

Object 6 "External movement - HVAC - switch" is identical to object 2 "External movement - light - switch".

4.2.4. OBJECT 7 INPUT - HVAC - FORCED CONTROL

→ Input 2 Bit

Object 7 "Input - HVAC - forced control" is identical to object 3 "Input - light - forced control".

4.2.5. OBJECT 7 INPUT - HVAC - DISABLE

→ Input 1 Bit

Object 7 "Input - HVAC - disable" is identical to object 3 "Input - light - disable".

4.3. BRIGHTNESS THRESHOLD SWITCH

1.1.1 25240 SG 300-3PIR > Brightness General Light Standby value HVAC Brightness Brightness value calibration Evaluation of PIR Constant light control Transmission of the lux value in case of change of Cyclical transmission of the lux value Brightness value threshold for switching Hysteresis Object value for ON Object value for OFF Transmission filter 100 Lux OFF 500 Lux 50 Lux OFF ON OFF ON ON and OFF

This block has two output objects: Threshold switch and brightness value

4.3.1. OBJECT 8 THRESHOLD SWITCH BRIGHTNESS - SWITCHING

← Output 1 bit

Output object 8 sends an "ON" if the measured brightness is greater than the Value for switching the threshold value switch parameter. If the measured brightness drops below the Switch-on threshold value – (minus) the Hysteresis parameter, an "OFF" is transmitted.

4.3.2. OBJECT 9 BRIGHTNESS VALUE

← Output 2 bytes

Output object 9 sends the current measured brightness value in lux. The transmission is triggered by changes that are greater than the parameter Transmission of the light value in case of a change of or cyclically with the time stipulated for Cyclical transmission of the light value.

If the cycle time is set to "OFF" there will be no cyclical transmission.

4.4. AD calibration value

← Output 2 bytes

Object 10 is not transmitted autonomously. It can only be read. Its unsigned 16 bit value represents the momentary value of the AD converter for the brightness measurement.

The brightness measurement can be calibrated as follows:

• Measure the incident light - on a desktop for example - with an external lux meter. This represents the reference lux value.
• Read out the AD calibration value (communication object 10) in the ETS.
  Note: In the menu Read/send value, use type 7.001 unsigned 2 byte counter!
  The AD value read then appears in the Value received menu as 739 pulses, for example.
• With full access, enter the two values Lux value and AD calibration value as parameters.

4.5. OBJECTS FOR CONSTANT LIGHT CONTROL

4.5.1. OBJECT 16 CONSTANT LIGHT - SWITCH ON/OFF

→ Input 1 bit

This input allows the constant light controller to be switched ON and OFF (Object).

Alternatively the constant light controller can be activated by motion detection on the light or the HVAC channel.

4.5.2. OBJECT 17 CONSTANT LIGHT - RELATIVE DIMMING

→ Input 4 bit

Using this object, the current value is changed with relative dimming steps of 1%.

Using a KNX push button, light can be dimmed and set to a new brightness level.

The new light value can then be displayed in Lux on a KNX touch panel through object 9: brightness value.

Important: In the menu constant light → take over set point after you can define the period during which the controller will remain switched off. After this interval, the new value is written to the RAM (not to the flash memory)!

Note: This new target value remains stored in RAM as long as there are people present in the scanned area. After switching the light channel off and back on again, the set point stored in ETS is adopted once again. If the newly changed set point are definitely taken over, set the parameter Keep changed set point to YES (see also section 3.8 Constant light parameter page 18)

The lux value is equal to channel 1 +/- offset.

5. PROGRAMMVERSION 2.7

With the program version 2.7, the function possibilities of the presence detector - series Swiss Guard 360P KNX / KLR RA / EA expanded and existing features of program version 2.4, have been supplemented respectively adapted.

The standard values (default values) of the parameters compared to the settings in version 2.4 are partially modified. These settings allow a simple and safe functionally check (initial start-up) of the presence detector.

Older devices of software version 2.4 can also be programmed with the program version 2.7 (backward compatibility). However, supplemented functions and the additional communication objects are not all supported.

Object forced control:

The object 3 as a forced control object knows 2 values (1 bit command) which can be received :

If object forced control = 1: output (Obj.0) remains locked when motion is detected, no telegrams are sent

If object forced control = 0: output (Obj.0) → AUTO (normal operation)

5.2.2. OBJECTS FOR DYNAMIC PARAMETER CHANGES

Input 2 byte

Output 2 byte

Via object 11 (delay time) and via object 12 (brightness below which sensor is active) may be changed or read the related parameter- values directly without to re-programming the presence- detector. This mode allows via external devices (BMS, touch screen, logic) to influence the functioning of the presence- detector directly.

For example, dependent on user needs, the light-ON switching characteristic / delay time can be dynamically adapted during certain day times to optimize the application

Changed values via object remain stored temporarily. After bus voltage interruption / return, after a reset or after a re-programming, the originally parameterized values are active again.

5.2.3. Object 14 CONSTANT LIGHT CONTROL - FORCED DIMMING

Input 4 bit

If the constant light control of the Presence detector is activated by a presence detection or by an external "ON"- command (obj1), dimming values (brighter or darker) transmitted to object 14 interrupt the function Constant-light-control immediately and remains inactive during motion detection and or the delay-time.

At that moment, the constant-light-control output-value (Obj 22) can with relative dimming (brighter / darker) by a KNX push button - to be changed.

After the delay-time or after an external "OFF" switching command, the constant-light-control is active again and operates (when motion-detection) with the stored parameter-values.

5.3. Parameters

5.3.1. Operating mode during power-on

After power -on/ bus voltage return or bus voltage interruption, the presence-detector is for the first 60sec inactive. During this stabilization-period of the electronic device, the detector doesn't sends any telegrams too.

Dependent on the application, in the operating mode "Automatic", the light output (obj1/obj22) can be activated during the start-up phase.

In this mode, two options with "75s light on after restart" or "no reaction after restart" can be selected.

1.1.1 25240 SG 300-3PIR > Light
General	Operating mode of the detector	Automatic (no reaction after restart)
Light	Green LED	Automatic (no reaction after restart)Semi automatic
Standby value	Delay time	Automatic (75 s light on after restart)
HVAC	Brightness below which sensor is active	500 Lux
	Brightness switch-off level	OFF
Brightness	Forced control object or disabled object	Force control objectDisable object
Brightness value calibration	If disabled object = 0	Automatic
	If disabled object = 1	Forced control OFF
Evaluation of PIR	Object type for output - light	Dim completely
	Object value for ON	100%
	Object value for OFF	0%
	Transmission condition for switching object	ON and OFF
	Transmission condition for external switch	ON and OFF
	Idle time after switch off	1 s

5.3.2. Automatic adaptation of the "light-off" threshold

With the setting "Automatic" in the parameter Brightness above which lighting is turned off, the detector calculates automatically the light-off threshold with the following rule: If the effective brightness with switched light-channel (after 1min.) is greater than the parameterized value, Brightness below which sensor is active", the light-off threshold is 10% increased above this value plus 200LUX.

If the effective brightness with switched light-channel (after 1min.) is below than the parameterized value „Brightness below which sensor is active“, the light-off threshold is 10% increased above the actual brightness-value (obj9) plus 200LUX.

1.1 25240 SG 300-3PIR > Light
General	Operating mode of the detector	Automatic (no reaction after restart)
Light	Green LED	OFF When motion
Standby value	Delay time	1 min
HVAC	Brightness below which sensor is active	500 Lux
Brightness	Brightness switch-off level	OFF
Brightness	Forced control object or disabled object	OFF
Brightness value calibration	If disabled object = 0	10 Lux
		20 Lux
Evaluation of PIR	If disabled object = 1	40 Lux
Constant light control	Object type for output - light	60 Lux
		80 Lux
	Object value for ON	100 Lux
		120 Lux
	Object value for OFF	140 Lux
	Transmission condition for switching object	160 Lux
		180 Lux
	Transmission condition for external switch	200 Lux
		220 Lux
	Idle time after switch off	240 Lux
		260 Lux
		280 Lux
		300 Lux

The light-off threshold is recalculated after each expired delay-time and a renewed motion-detection or an "ON" switching-command.

If the parameter Brightness switch-off level is selected with a fixed value, this value needs to be higher or the same as the parameter Brightness below sensor is active.

5.3.3. Delay-time, mode semi-automatic

If the brightness is increasing during the delay-time and passes over the threshold "Brightness switch off level", the light-channel (obj0/obj22) is switching off but the delay-time is continuing either. If the brightness reduces below the value "Brightness below sensor is active", the light channel is switching "ON" again, till the delay-time is expired.

5.3.4. Standby-functionality

When the light-channel is used as "dim completely", a standby-light can be activated optionally.

Two pairs of values are available and can select with obj24.

The delay-time for the Standby-functionality can also parameterized as "Unlimited" too. Emergency-light

with permanent minimum brightness.

If the brightness during standby increase over "Brightness switch off level", the light-channel (obj0) is switching off.

If the brightness reduces below the value "Brightness below sensor is active", the light channel is switching "ON" with the standby-settings again till the delay-time (standby) is expired.
