Niko PIR sensor with Loxone - not working correctly

[Sungray]

Hi,

I'm having troubles plugging Niko 350-30010 motion sensors. There are 4 connexions in the motion sensor : 24V, -, lux and PIR.

Product page : http://www2.niko.eu/enus/article/350-30010

Niko sensor -> Loxone
'+24V' -> +24V
'-' -> GRND
'lux' -> analog input 0-10v
'PIR' -> digital input

Surprisingly, the lux seems to work fine (I read somewhere it wouldn't). But not the rest.

If I plug the '-' to the ground in Loxone, the PIR command is not sent to Loxone. Should I not use the '-' from the motion sensor ? When I unplug the ground, the command is accepted and the lights are on. But I don't like that, as I am guessing if this connector exists, it must have some utility :D.

Also, I don't know why, the range of the sensors is very limited, maybe 2 meters max instead of 15 according to specs. They are placed 2 meters high, in a corner, facing the center of the room, slightly pointing towards the gound. I've tested several sensors of the same model using the test jumper, they all act the same. I've tried increasing the sensibility for no better results (at max settings it's always detecting movement of course but probably just seeing spirits). Maybe I plugged something wrong. Any advices ?

Thanks !

I'm using these successfully - see attached photos

24V + to terminal 1

24V ground to 2

connection to Loxone digital input on Terminal 4

Per SmartBusinessTools.be (who I bought mine from) :

"Inside the detector, a pull-up resistor needs to be added between the 24Vdc and the Signal-Out. We add this resistor to the package. On no detection, the signal is high (+24Vdc), on detection it drops to Ground. In Loxone, you need to invert the digital input (add a dot on the input)."

One of mine is working successfully in a hallway at about 5 or 6 metres.

I notice the SmartBusinessTools page also says:

"Sensitivity can be adjusted. On high sensitivity, you can program Loxone to interpret the level of motion or presence, based on pulse width and/or counting pulses."

Can anyone explain how to do this?  Sounds an interesting refinement 

[Sungray]

I see a resistance between 1 and 4. Is that a 4.7kΩ resistance ?

Thanks A LOT you're saving me.

One thing I don't understand though : "In Loxone, you need to invert the digital input (add a dot on the input)." Care to explain ?

If you click your mouse on an input of a block in the configuration a ‘dot’ will appear (in the same way you set the ‘remanance’ input where you want a block to remember its state after a power cut or a reboot) . This inverts the input - ie if there is no signal Loxone will think there is and vice versa. in the case of the movement sensor I’m assuming that the ‘PIR’ output is ‘high’ (presents a voltage) until a movement is detected when the voltage drops.

[Sungray]

Ahh didn't know that one. Thanks !

Hi,

we are having issues with the Niko 24V sensors as well. Is there a specific transistor we need to use with these sensors?

Any advice appreciated.

Mine appear to be 2.2 K ohm (3 red bands)

Ok thanks Simon.

I will try and get the same resistor. Basically the sensor  is constantly ON and even if we invert the signal it doesn't respond.

Take care.

In orde to have the in-ceiling 24V Niko motion sensor working correctly with Loxone, is it obligatory to install the resistance inside the sensor?

The reason I'm asking is that I have just ordered one to use together with my Loxone installation, but I didn't come accross this tread before I ordered.

So to avoid that I'll be messing around with something that wouldn't work anyway in the default configuration, I would rather know upfront :).

[Simon Still]

Yes it is.   

[Balj]

Simon, yes you need the resistor. It won't work without it. Order from eBay etc.

I can't remember the ohms but i think it was 22ohms.

Take care.

I used a 22k ohm resistor and it works like that.

On another forum I saw a mention of 10k, so maybe the exact number doesn't matter, I guess there is a certain range of resistors that can get it to work.

[amb5l]

The PIR output is the collector of an NPN transistor so if you were connecting it to a classic intruder alarm (say a Texecom panel), the normally open / ground on motion approach would "just work".

You MUST use a pullup resistor if you are connecting to a Loxone digital input, and invert the signal with logic in your config. Current will flow in the pullup resistor when the output is active (grounded). For a 24V supply, and a 22k resistor, the current will be (ignoring the Vce of the transistor) I = V/R = 24/22000 = about 1mA which is fine.

Don't use a 22 ohm resistor unless you want to let the smoke out of it!

Old topic but maybe still alive :-)

I have the Niko 350-30010 sensors working with my Loxone system but only for motion.

I would like to use the lux sensor as well.

Do I need to use some kind of resistor to get this working or does it work out of the box?
