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.

UPPLY

 

It  is  possible  to  choose  between  two  different  options  to  supply  the  SRKNX:  using  an  auxiliary  power  supply 
(recommended) or through BUS KNX.

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:
