Interests of the infrared motion detector

The infrared motion detector is a very practical technology which differs from so-called conventional ignition systems (switches with back-and-forth connection for example) in the sense that it requires no action on your part so that the light point to which it is connected alight.
Indeed, a light working with an infrared motion detector turns on as soon as the latter distinguishes infrared radiation (light invisible to the naked eye emitted by objects and bodies in movement by day and by night): no need to get up and move to turn on the light, the detector does all the work for you!

Install an infrared detector outdoors instead of conventional switches is therefore very interesting: it allows to illuminate the outdoor spaces without action on your part, which is for example practical when you return home at nightfall (you do not have to search for the switch to illuminate your porch or your outdoor spaces)! Likewise, this saves you from leaving your outdoor lighting on all the time, for example if you are expecting guests in the garden; without forgetting that the infrared detector will warn you directly of their presence when the outside light comes on!

Connect an infrared detector to a back-and-forth: why?

Given the practicality of the infrared motion detector, the relevance of make a connection to a two-way switch can arise. Why bother to couple a system that works independently to a conventional ignition system?

In reality, associating an infrared detector with a back-and-forth connection makes it possible to "force" the lighting to go on without taking into account what the motion detector says. This can be useful when you know that you are going to need light longer than the ignition time programmed by your motion detector: this will prevent the light from going out after 5 minutes, and you have to go back to the infrared detector to restart it!

Connecting an infrared detector to a back-and-forth: how?

A infrared motion detector works with 3 wires: two terminals for the power supply (phase L and neutral N), and a third which will be connected to the lighting concerned.
To be able to activate the infrared detector in manual mode and couple it to the back-and-forth connection, the red wire L and the blue wire N must be connected to the back-and-forth. Thus, when a presence is detected, the device will contact the phase of the power supply with the lamp, which will trigger the lighting.

To note: wireless detectors are more and more widespread, connect an infrared detector to a back-and-forth is an operation that is almost obsolete today!

Connecting an infrared detector to a two-way switch: precautions

If you want install a motion detector yourself on a back-and-forth connection, know that this operation is reserved for experienced handymen with good knowledge of electricity only.
Remember to always carry out the operations after cutting the electrical supply to your circuit, and to restart the power only once the site is finished to check your work.

Of course, in case of doubt or hesitation, do not hesitate to call a professional: it will cost you more than doing the work by yourself, but it will ensure you a perfect result, safely and without getting tired ...
