Presence sensors respond to real room shapes
Steinel’s Control Pro system of presence detectors for controlling lighting have square-shaped detection characteristics that are said to be better suited to the layout of rooms such as offices and conference areas than the round attributes used by conventional presence detectors. According to Steinel, ‘Never before has it been possible to cover offices and commercial areas with presence detectors without overlaps or leaving gaps. Using Control Pro, zones can be planned perfectly, with reliable detection at every point of the room and up to 4800 switching zones.’
The system used infra-red and high-frequency sensing technologies to suit ‘regular’ areas such as small offices and meeting rooms, as well as large, unusually shaped areas that may contain ‘obstructions’, such as open-plan offices, large conference rooms and restrooms.
Output signals include switching output, HVA output, 1 to 10 V for dimming, KNX/EIB and DALI. Retrofitting to existing lighting is said to be very simple.
