Product description
The ekinex
®
EK-SN2-TP sensor is a passive infrared (PIR) indoor presence detector based on KNX
standard, with movement function and wall switch. It is designed for the detection of movement /
presence of people in shops, offices, small rooms, residential areas such as corridors, stairs,
bedrooms, etc., in order to drive lighting and HVAC systems.
The detection area has a coverage angle of 200° and it can be extended using other sensors
con
figured as slave devices. An integrated light sensor, combined with the motion detector, can
manage light switching depending on brightness level as well as presence.
The device has two distinct output channels for lighting control, with independent parameters; the
operation can be automatic or semi automatic.
The device is also capable of maintaining a constant brightness level in the room by controlling a
dimmable light source.
All of the above parameters can be set by the user either through KNX ETS
®
software.
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
Hidden switch, can fit single round or square wall flush-mounting box
Simple and safe plug-in installation
The presence detector is used to control devices, e.g. lighting and HVAC
Learning function, to configur
e the device functions by reading the “ambient Lux” parameter
Semi-automatic or fully automatic operation
Evolved lens model, with well-distributed and concentrated detection capabilities: the
detection beams also provide high intensity and sensitivity, so it is possible to detect even a
small shaking movement of the hand
Adjustable sensitivity via ETS
®
on 4 levels or with "Walk test" to verify detection range
Operating modes: Manual ON / AUTO / OFF
An additional device can be used as slave for any of the channels
Use in the KNX TP bus system (twisted pair) in combination with other KNX devices
