Sip Counter Digital sensor externe

hello,
I'm new to the forum, I'm from belgium.
I'm trying to mount an external sensor for SIP counter KOSO SA 07
Someone is already using this system?
Could you take a picture of a face so see or look exactly the sensor.
With this active sensor, I think that we should not put magnets?
Thank you for your answer.
