Domoticz

So I am totally new to home automation and z-wave, I've got the aotech gen5 stick running on a raspberry pi 3 with domoticz, I bought a lamp dimmer which is simple enough and works and an ecolink door sensor to test door/window sensors. I noticed that it has added 4 devices to my list and some of them are obvious, but I am not sure how to use them all if that makes sense. The sensor part seems simple enough, then there is alarm type, alarm level, burglar, how do I use these? I have them all set to contact sensor type. If there is a good website that explains a lot of this stuff I'd much appreciate a link, thanks!

z-wave devices often comes with unnecessary (for most people) sensors like "burgler".
Burgler is if somone try to open the sensor.

On my devices i just find out what devices is doing what I want, and don't use the other devices.
But i rename all mye devices to somthing so I in the future can use them.
