HF detector technology can be used in lights or other products that need to be installed without obvious sensor elements. The motion detection uses the Doppler Effect to track movement.
Moving people or things cause a phase shift in the reflected radio signal from the detection zone. The emitted radio signal is only sent as a pulse, with a capacity of less than 1 mW. This means that the signal is more than 1000 times smaller than the signal of a conventional mobile phone. Unlike presence and motion detectors that use passive infrared technology, the HF-detector recognizes a person or thing best, if they/it move(s) directly towards or away from the detector. Normal reflections from walls, ceilings and floors will nevertheless register all movements in all directions very quickly. Unlike infrared motion sensors, movements that are not within the direct field of view of the detector can also be picked up. In such cases, the sensitivity of the detector can be dialed to the desired range.
The HF-detector was designed to ensure optimal data collection from inside a light. To achieve this, the emitted signals must overcome the resistance of the light housing. Metallic elements fully absorb the signals, while stone can be a heavy filter depending on the thickness. The RF signal will pass relatively easily through other elements such as glass, wood, plaster or plastic. Therefore, depending on the environment, even movements that take place behind room dividers made of permeable materials can be monitored.
For this reason, adjust the sensitivity so that only desired movement is tracked. Also to keep in mind, an RF detector reacts more sensitively to moving metallic objects than to other materials. If the light is intended for outdoor use, ensure the correct positioning of the detector, especially if in close proximity to street traffic, and adjust its sensitivity. Heavy rain or snowfall can also trigger unwanted switching at high sensitivity settings. The motion detector must be installed in such a way that it is protected from direct weather influences.
The sensitivity of the Züblin HF-detector can be adjusted over a wide range, to ensure optimal motion detection.
If an RF motion detector is used in a lamp, please ensure that the light incidence on the twilight sensor is also filtered through the light cover. That way, the low-light sensitivity can be increased with a switch on the detector, depending on the cover.
Presence and motion detectors with passive infrared (PIR) technology are among the most reliable types of detectors today, both in terms of detecting a moving person and low maintenance. The PIR detector responds best when the movement takes place tangentially to the detector. Range specifications are typically designed for such movement. Radial movement directly towards the detector or away from the detector results in a technologically-induced reduction in the range and sensitivity (up to -50%), which must be considered when positioning the detector.
Mount the motion detector on a solid wall or ceiling ensuring the detector is not subject to wind, vibration etc. These disturbances will have the same effect as the movement you intend to track.
When determining the installation location, consider the mounting height of the sensor (for outdoor installation), the receiving angle, distance to nearby streets, and adjacent property, trees and shrubs, to avoid unwanted interference.
Each PIR motion detector responds to the rapid change of thermal radiation in the detection zone. Raindrops moving over the lens can trigger unwanted switching. Motion detectors should be installed in such a way as to protect from rain, wind and direct sunlight where possible.
Please ensure sure that sufficient distance is provided between the motion detector and connected lighting. Heat from lights near the detection field of the sensor will bring about a change in temperature, causing the sensor to switch off and on again. Spotlights and bright lights pointed directly at the motion sensor may disturb operation of the twilight sensor.
The range covered by a sensor can be restricted by adjusting the sensor head (when motion detectors are installed outside buildings) or by partially covering the lens with masking foil or lens covers. Use the same technique if you wish to limit a specific part of a detection field.
If the motion detector is used to switch network-parallel inductors such as: relays, circuit breakers, fluorescent lamps, or LED power supplies or transformers, we recommend the use of a RC quenching unit (snubber) in parallel to avoid peak currents during the switching process. To ensure reliability and product longevity, we recommend 3 to 4 parallel detectors in a group. If more detectors are required for the planned coverage, use the detectors in a master/slave configuration. Up to 10 slave units can be attached to a Züblin detector device.
Züblin movement and presence detectors were developed for the automation of lights to increase comfort and energy efficiency. They are not suitable for use with intruder and robbery alarm systems, and were not designed to those specifications like EN 50131 (ff.).
Passive Infrared (PIR) Detector Troubleshooting.
Several factors can interfere with the proper operation of a motion detector, including temperature change, reflections in the detection area or poor connections.
