In fact compatible with Abus Secvest 2Way

I took the risk and have ordered the inexpensive replica (or the original) of Cooper.
As far as I've read, Abus can build its system of Cooper, so I have been confident,
that compatibility is assured.
And actually, I have to integrate two of the motion in my existing system immediately. Pfuh!

The motion to see the outside identical to the parts of Abus, the plastic was just a touch yellowish.
Included is also an attachment, with which you can mount the motion detector in room corners.
I mention this because this attachment is not displayed and it is also included in the Abus parts.

I will continue to monitor the motion detector during operation and update my experiences here.
