Motion detector with orientation light and contactless switch in one

The Gira Sensotec LED uses an integrated LED light to provide orientation lighting that switches on automatically, thereby uniting the functions of a motion detector, an LED orientation light, and a contactless switch within a single device for the first time. Like the Gira Sensotec, the Gira Sensotec LED also works using a high-frequency sensor. When motion is detected, the integrated LED orientation light discreetly illuminates its surroundings to provide orientation within the space. The light intensity can be set to the desired level of brightness to avoid glare. If more light is desired, the user can switch on the room lighting without contact by moving within 5 cm proximity. Combining these functions in a flush-mounted box saves installation space and reduces installation and device costs. The Gira Sensotec LED is particularly suitable for areas where subtle lighting is sufficient for orientation in the dark, e.g. hallways of homes. The LED orientation light is harmoniously integrated, giving the Gira Sensotec LED a very pleasant appearance on the wall. The Gira Sensotec LED can also be used in conjunction with a coupling relay as a contactless door opener in public toilet facilities, or in hospitals, nursing care facilities and medical practices.

  • Flat design that integrates well into any architecture and offers a wide range of design options
  • Motion detection in the long range: Automatically dimmed room light, without glare
  • Detection through doors and walls
  • Individually adjust range
  • Reliable detection even at high temperatures
  • High-frequency sensor when compared with PIR technology
  • Motion detection in the close range: switch on the lighting without contact. The switch remains clean.
  • Increasing the range using reflected signals does away with the need to install additional devices
  • Glare-free due to adjustable light intensity
  • Open doors without contact, close up or from a distance

Flat design and a wide range of design options

High tech in its slimmest form: The Gira Sensotec LED is very slim – e.g. in the case of the E2 frame range, it is only 2 mm deeper than the frame – and its flat design looks elegant and yet inconspicuous on the wall. The frame and top unit, including flush-mounted LED orientation light, are almost on one level and easy to clean. The device can be integrated into System 55 frames and the F100 (with adapter frames). Five colour variants provide a wide range of design options.

High-frequency sensor when compared with PIR technology

Motion is detected using the Doppler effect: The high-frequency sensor (HF) emits electromagnetic waves with a frequency of 5.8 GHz. If the signal hits an immobile object, such as a piece of furniture, it is reflected at the exact same frequency – whereas if there is a person within that space moving towards or away from the sensor, the frequency of the reflected signal will be increased or reduced. The Gira Sensotec LED registers this change as motion and turns on the room light in dimmed mode as a result. A motion detector using PIR technology and a passive infrared sensor detects the invisible thermal radiation from moving bodies. Advantages of HF over PIR technology include, for example, precise detection at high temperatures and detection through penetrable materials. With the Gira Sensotec LED, optimal detection occurs when people move directly towards the device. By contrast, PIR detectors work best when people move at right angles to the direct approach line.


Motion detection in the long range: Automatic LED orientation light

If something moves in the detection range, the integrated LED orientation light is automatically switched on if a defined brightness threshold has been reached. This makes orientation easier in the dark, thus improving security and convenience. The light intensity of the dimmable LED orientation light can be set at a level sufficient for orientation purposes in living areas and smaller hallways. At the same time, the LED indicates where the switch for the room light is located.


Motion detection in the close-up range: switch on lighting without contact

The room lighting switches on at full intensity when the user comes within approx. 5 cm of the Gira Sensotec LED, for example by making a hand movement within this range. This is particularly simple and convenient and also makes it easy for people with tactile limitations to turn on the light.


Detection through doors and walls

Motion can even be detected through materials such as glass, stone, plasterboard and wood.


Increase range through reflected signals

Metallic surfaces and concrete walls or solid masonry dampen or reflect the signals. Detection through these materials is possible only to a limited extent or not at all. However, the reflective effect can also be used to extend the range. In rare cases, the range may also be reduced.


Individually adjust range

In open spaces, the Gira Sensotec LED’s range covers an area of about 4 x 6 m. The sensitivity of the sensor can be adjusted using the remote control. Detection in neighbouring rooms can be avoided due to its good adjustability.


Glare-free due to adjustable light intensity

This makes it unnecessary for the full room lighting to be turned on as it normally would, e.g. in hallways, leading to glare effects. The integrated LED orientation light is dimmable and can be set at a pleasant, yet sufficient brightness level. The Gira Sensotec LED also factors in the adaptability of the human eye and follows the recommendations of the guideline VDI/VDE 6008 Sheet 3 for barrier-free living spaces.


Reliable detection even at high temperatures

The Gira Sensotec LED can detect movements reliably even at high temperatures and in areas with heat convection such as staircases. By contrast, a conventional infrared sensor can barely distinguish people from their surroundings at temperatures in excess of approx. 28 °C – thus no longer fulfilling its function reliably.


Areas of application and examples of use

The Gira Sensotec LED is suitable for all locations where subtle lighting for orientation is desired. Due to its slimline design and the integration of several functions in just one device, the required building technology on the wall is pleasantly unobtrusive.

Open doors without contact, close up or from a distance

If the Gira Sensotec LED is used in conjunction with a coupling relay as a door opener, doors can be opened without contact solely at close-up range, or at close-up and long range, depending on the setting. If the detection range is set to the lowest distance level, the door will open only at close-up range, i.e. at approx. 5 cm (e.g. in treatment rooms). If the detection range is set to approx. 6 m, for example, and the dimming value is set to 100 %, the door can be opened by a movement both in the long and close-up detection ranges (e.g. connecting doors).

Safe orientation in the early-morning darkness

People’s eyes are particularly sensitive when they get up in the morning: The LED orientation light can be adjusted to a level of brightness sufficient for orientation, with no glare. And once your eyes have got used to the light, you can switch on the room light with a swipe of your hand in the near-field range.


Planning guide

The Gira Sensotec LED makes use of HF sensor technology based on the reflection of electromagnetic waves. Detection depends on the reflecting surface, speed and the type of object. When installing the device, consideration should be given to the spatial conditions, materials present and typical directions of motion within the room.

Mounting height

The Gira Sensotec LED should be mounted at the same height as normal switches, at approx. 1.10 m.

Select an installation point based on the direction of motion

In contrast to motion detection using PIR technology, HF sensors are best at detecting people or objects that are approaching them directly. If the only possible installation point is one where movements will usually occur at right angles to the device, we recommend installing a motion detector that uses PIR technology – e.g. the Gira automatic control switch with Standard or Komfort top unit.




Behaviour with certain materials

Motion can even be detected through materials such as glass, stone, plasterboard and wood. Reflective materials such as brick walls, metal doors and the like can significantly increase or decrease the front or side range.


Backward detection

Some slight backward detection is possible through flimsy walls, e.g. plasterboard. In safety-relevant areas this must be avoided.


Limiting the detection range

The range of the sensor should be appropriately configured to prevent any undesirable detection in neighbouring rooms.


Installation

The flush-mounted device is connected to the 230-V power supply. A load (typically a light) can be connected to the electronic output. After the device has been connected and the power supply switched on, the device will need approx. 30 seconds for initialisation, after which it will be ready for operation. The following parameters can be adjusted using the infrared remote control: Brightness of the orientation light, sensitivity (range) of long range detection, walking test (detection field)/overrun time = 1 sec., threshold setting for max. ambient brightness (light will not be switched on if this value is exceeded), overrun time setting, Master / Slave switchover – if several Sensotec devices are used in combination, only the Master's brightness and the behaviour when switching off will be analysed. Blue and red LED signals provide the installer with programming assistance. If a coupling relay is attached to the output of the Gira Sensotec LED, loads such as wound or electronic transformers, compact fluorescent lamps, fluorescent lamps or an electric door operator can be connected. The output of the Gira Sensotec LED can also be connected to a KNX binary input if the dimming setting is at 100%.
