Web search for a CR1 X10 Water Sensor made by Minotaur Engineering.
Looks like sold exclusively through Smarthome as the Minotaur site linked directly to Smarthome.
http://www.smarthome.com/71932/X10-Water-Moisture-Sensor-CR1/p.aspxVery sketchy users manual. Indicates it was originally made for a X10 Powerflash Module and that the Input Mode 'A' was what was used.
That is the low voltage Input Type. So without details. It looks like it outputs a low voltage that can not be directly used by the SC1200.
Also mentioned a wall wart power supply. That is not shown on the photos but is included from what the manual says.
The WaterBug WB-200 has dry contact outputs and could be hard wired to one of the two wired zones on a SC1200.
I am trying some tests on a WB-200 with an Insteon I/OLInc and later can try it on my SC1200.
Update. The WB-200 can be connected to either wired zone inputs. Will trigger an alarm if armed or sound the chime if not armed and the chime option is On.
