This manual describes the connection of motion detectors to the digitalSTROM system. For this purpose the digitalSTROM terminal block SW-AKM200 is used. digitalSTROM also offers motion detectors, which have already pre-installed a terminal block and can thus be integrated directly.
The automation terminal blocks of the SW-AKM200 series can be trigger a large numer of actions in the digitalSTROM system via connected switching sensors. Since input changes are processed very quickly by an AKM, it is also possible to connect short-cycle switching systems such as motion detectors in order to control lighting or detect presence.
Since the digitalSTROM system works with centralized and continuous circuits, motion detectors can be accomodated where they optimally capture a room. The connected SW-AKM200 terminal block signals the detected movement via the nearest circuit equipped with digitalSTROM. A complex wiring is not necessary.
There are a variety of motion detectors that differ in quality, comfort and design. However, all commercially available motion detectors have an output that - depending on a detected movement - is connected via a relay to the mains voltage.
Motion detectors with a potential-free contact can also be used if the relay is suitable for mains voltage. This information can be found in the data sheet of the device.
As you can see on the pictures, the electrical connection is very easy. The terminals L and N of a SW-AKM200 terminal block are connected to the mains; the grey input of the terminal block is connected to the switching ouput of the motion detector. For potential-free contacts in the motion detector, the common relay contact is connected to L and the make contact relay to the input of the SW-AKM200.
The SW-AKM200 terminal block series up to SW-AKM220 only differ in the number of inputs.
The setting screws for the switch-off delay are set to minimum, the brightness can be set to an appropriate value. Alternatively, set the brightness to the highest sensitivity and enter the times of day in the digitalSTROM configurator when the motion detector ought to switch. The latter has the advantage that you do not have to work directly on the motion detector for later adjustments, but can easily adjust everything via PC or tablet from your sofa. In addition, you can also use motion detectors without brightness control without sacrificing energy efficiency.
