Product description
The ekinex
®
presence detector is a KNX S
-
mode device for the indoor detection of occupancy and
movement of people, with an effective detection range of 360° thanks to its three passive infrared (PIR)
sensors.
The detection range can be further extended by employing more ekinex
®
presence detector devices as slave
units. Two channels C1 and C2 are available for the lighting function; these can be used to achieve a
constant brightness control by using C2 as an offset input respective to C1 (from
-
50% to +50%).
The light intensity in constant brightness control is measured by the integrated brightness sensor; its value is
made available for bus transmission in Lux units (2 byte). An orientation light function can be programmed
with a standby value (in %) and a duration value (in minutes or hours).
The channel dedicated to HVAC applications allows the independent control of terminal devices dedicated to
Heating, Ventilation and Air
-
Conditioning.
The device is equipped with an integrated bus communication module and is designed for ceiling flush
mounting. Several versions are available which differ in the detection range and in the lens and frame type.
The device power supply is taken from the KNX bus and no auxiliary power supply is required.
2.1
Versions
The device is available in four versions which differ in the detection range (either 16 or 30 m) and the frame
shape (round or square).
