2. Function and performance characteristics
The presence detector ECO-IR DUAL-C NT detects persons within a room
on account of slightest movements. Simultaneously, its two light sensor
measure the brightness in two different zones of the room (A = window zone,
B = inner zone) and compare them to the preset brightness thresholds.
Two relays serve as switching outputs. ECO-IR DUAL-C NT is used pre-
ferably in large rooms in which several lighting groups must be switched after
different brightness values. A mechanical safety lock protects the detector
against unauthorised removal.
Two switching contacts A and B «Light»
switch on the lighting in case of
