Mounting heights, room sizes, detection geometry and indoor climate conditions – individual building needs are frequently complex. The right solution can quickly be found though with a modular sensor kit consisting of diverse, variably settable sensors. Several questions must however initially be answered to enable correct selection. Detecting traversing movements Detecting occupancy Utilisation of daylight Motion sensors respond to walking and vehicular motion. Occupancy sensors feature more sensitive detection than Light sensors measure the quantity of ingressing daylight on They perceive this within their detection range and respond motion sensors, responding to the slightest movements with a reference surface in a building. If the illuminance level falls accordingly. extremely high resolution technology, for example with desk below a preset nominal value, artifcial light is added work. Each occupancy sensor is also a motion sensor, according to requirements (more information from page 36). although not all motion sensors are occupancy sensors. Tangential detection (also 'transverse detec- tion'): specifes the distance from which motion transverse to Sensor the sensor is detected. Radial detection (also 'frontal detection'): specifes the distance from which motion directly Can a sensor carry out towards the sensor is detected. several tasks simultaneously? Yes – multi-sensors enable the combination of occupancy For professional, long-term use of sensors, these factors are and motion detection as well as daylight-dependent control taken into account during the systematic determination of of light. These all-rounders can however only be used with a requirements and subsequent planning. single function, i.e. only presence and motion detection or Ask your OSRAM / Siteco sales representative. only daylight-dependent lighting control. With multi-sensors it should be considered that the detection ranges of individual functions vary. 4 5 Diagram: © Steinel Vertriebs GmbH Fundamentals | Technology Fundamentals | Technology Which technology is most suitable? Two sensor technologies are suffcient to fulfl all standard demands for motion and presence detection, and one technology is not better than the other. Intelligent use depends on the specifc requirements, and a fundamental differentiation is made between the basic sensor types of passive infrared or high frequency sensors. Segmented lens Pyro-sensor PIR Passive infrared sensor: PIR sensor HF High frequency sensor: HF sensor Infrared sensors perceive heat radiation, for Detection angle High frequency sensors actively sample their example from moving persons and vehicles. detection range. As with bats, signals are sent out Moved warm objects are detected by high- and then received as refected echo signals. sensitivity sensors as voltage variations. Modifcations to the echoes correlate to the The detection precision of a sensor depends detection of movement, implemented without on its resolution and the number of detection delay and independent of temperature – i.e. zones. without limiting sensitivity due to motion direction or temperature. Detection features — faceted lens Detection features — closed housing Benefts Active zone — high resolution Passive zone Benefts — insensitive to vibrations — wide range — temperature-independent — covered mounting is possible Tip: determining the right mounting location for PIR and HF sensors Selecting the right installation location for a sensor prevents erroneous switching, triggered for example by temperature fuctuations, strong draughts or vibrations. Sensors must be mounted so that their detection ranges are not impaired by machines, cranes, vehicles or doors.

Fine adjustment of the detection range is possible These shields can be ftted without use of tools or can be with almost all sensors. According to the type of sensor, pulled out with sensors embedded in luminaires. this is either electronically via remote control (HF sensors) This then excludes the detection of undesired areas. or mechanically via shields (PIR sensors).

Modular and integrated – two basic concepts for differing Hardly visible constructional and visual requirements Sensors integrated in luminaires have precisely specifed detection ranges for their applications. Modular concept Various sensor heads can be rapidly ftted without tools via the Modario® socket module, this being pre-assembled to a support rail, which in turn is simply connected to other rail elements with new installations. It can however also be retroftted with many existing lighting installations. Extra cabling for sensors is not needed thanks to the socket module, and sensors are matched to the luminaires and can be combined with suitable control systems. Integrated sensors Variable Sensors are fxed with a Sensors integrated in luminaire bodies are frequently the best choice single hand movement, for offces and other prestigious environments. Multi-sensors are of and exchanging sensors course also available, and many luminaire ranges such as the Mira® is also simple if needs and Vega® can be equipped with sensors. The luminaires are then change. factory-supplied with embedded sensors.

The precise determination of detection ranges provides major savings potential, especially in large halls, as these can be divided into precise segments during the planning process. In this way only the specifcally required area is illuminated but not the complete hall. High quality and strong-range sensors with circular detection are especially suitable for car parks and under- ground garages, facilitating standard-compliant and energy- effcient lighting. Another important factor is that parking areas completely covered by sensors signifcantly increase the subjective feeling of safety.
