What Kind of Door/Window Sensor is this?

I found this one laying around the house. I’m not sure if it was left over from Vivint or TWC. I can’t seem to learn it into the panel though.

That does not look like any Honeywell/2GIG compatible sensor I am familiar with.

Is there a visible model number anywhere?

No model #. I even took that sticker off on the inside and there’s nothing under it (except a chip), no numbers whatsoever. I think it may be left over from TWC. Their system was Zigbee I believe.

Just making sure before I tossed it. Thanks.
