Practical advantages of presence detectors

Due to their very fine sensor technology, Theben presence detectors detect even smallest movements and temperature differences. In this way, they allow to exactly adjust light and climate to the needs of inhabitants and users. Depending on the model, the various presence detectors are available in the colours black, white, grey, silver or in special colours upon request.


	Square detection area The square detection area is ideal for most rooms in which presence detectors are installed. In this way, the individual detector scan be perfectly arranged. Without any gap or unnecessary overlappings. Without blind spots. This makes planning easier, reduces the installation effort, saves energy and lowers costs – because, due to the square detection area, usually fewer detectors are needed.
	Self-learning time delay Depending on how people behave inside the room, the time delay changes automatically. If the presence detector detects more movement, the time delay is shortened to just two minutes. If people hardly move or only rarely, the time delay is increased to up to 20 minutes. This saves energy, increases comfort and allows people to work in their most efficient way: active and lively or still and focused.
	Sensitive room surveillance A presence detector misses nothing. This is a particular advantage when the presenc edetector is integrated in the building system technology of large office or administration buildings. In this way the building management always know in which rooms people are still working.
	Safe staircase light function With presence detectors, nobody trips up. Not even on the stairs. The light can be turned on using the buttons, but it only goes off when there is no movement on the stairs anymore. This means that someone who is at the top of the stairs is not suddenly left in the dark because someone at the bottom has switched off the light.
	Illuminating short stays In the event of a short stay, the light is only on for two minutes. Since presence detectors "detect", whether and how long someone is in the room. This means that whoever enters the room for a short period of time does not automatically trigger the time delay that has been set and therefore does not have to go without light.
	Individual light scenarios Bright daylight or soft dimmed light – You can choose between two lighting scenarios you can define however the mood takes you. For example, in conference rooms where the light has to be dimmed for presentations. For exactly those lighting arrangements that are necessary for everyday situations. Settings can be made, saved and changed quickly and easily using the remote control.
	Easy to use remote control With a remote control, settings can be easily made and changed from ground. This is faster, shortens installation times and lowers costs. And, moreover, it is safer.
	Clever teach- in function Lighting conditions change quickly – it is good if you can simply save them when they are exactly how they should be. With the clever Teach-in function, the current lux value can be continuously saved. Without specialist knowledge. By the end user. It couldn't be easier.
	Constant lighting control Some versions have constant lighting control, which permanently compares artificial light and daylight. They determine the desired brightness value from these two light sources. No matter how changeable the weather: The lighting conditions inside the room remain pleasantly constant.
	Sensitivity that can be set It is up to you, how sensitive presence detectors respond to movements inside the room. The PIR sensors can be conveniently set using the remote control – according to the individual requirements of the users.
	Suitable for damp rooms Presence and motion detectors with protection class IP 54 can also be used in damp rooms such as showers, changing rooms or toilets.
	Practical pulse function The pulse function allows the presence detectors to be built into existing electrical installations with staircase light timer switches or KNX binary inputs without the need for expensive adjustments.
	Most simple energy saving setting „eco” stands for optimum switching behaviour. „eco plus” for maximum energy savings. You decide what is best for you at the push of a button. Just as you want. Exactly how you need it. There is no easier way to save energy.
	Intelligent parallel switching Presence detectors allow for more than just increasing the detection area via Master/ Slave switchings. Via Master/ Master/ parallel switches the lighting conditions can be set in the detection area of individual devices independently, without depending on other devices and therefore individually. That is an advantage if, for instance, in open-plan offices, different lighting conditions are to be balanced between areas close to windows and the room's interior.
	High switching capacity Theben presence and motion detectors have a high-performance relay with tungsten pre-contact or a zero-cross switching and can thus handle switch loads of up to 10 amperes. This allows several lamps to be connected at the same time and larger areas, such as loading ramps or hotel premises, to be lit. This improves planning security, lowers costs and reduces installation times.
