Ah, yes, Z-wave Flood Sensors (and all Z-wave Sensors in general) are not typically compatible with any Alarm panels. Command classes for z-wave sensors are not enabled. The panel’s Z-wave radio does not affect the alarm state of the panel.
Alarm panels will utilize sensors in their corresponding RF frequency. (For 2GIG, an RE219, for example)
See below info on water management:
"It is not one particular part or product that is specifically designed for monitoring your sump pump. In the case of the previously mentioned blog post from Alarm.com, it is two separate parts.
It requires you to install a Water Sensor and a Heavy Duty Smart Switch. Depending on which panel you are using would determine the appropriate part to purchase. As an example, you could use a Resolution Products 119/219 Flood Temp Sensor and an Aeon Labs Heavy Duty Smart Switch, provided the smart switch works with your panel correctly.
The two working in tandem can detect when your Sump Pump fails (the Heavy Duty Smart Switch takes care of this function) and when the water level gets too high (this is the Water Sensor’s job).
In addition to having these installed, you need to be signed up for the Gold Interactive Package and have the Water Management add on activated." - From here.
