One thing I'll mention... there's some sort of water-detection or some sort of alarm that's built in - I haven't programmed in a while, so I don't remember the specifics, just the broad strokes... If you use the water sensor and it's tripped, the elk sets off the full blown alarm including siren, if I remember correctly. Your best bet is to set it to a full non-alarm zone and use rules to create the desired behavior. I wish I could elaborate more, but at the very least, it's worth another search. If needed, I can do some more research for you if requested.
