Following on from my projects thread here regarding my new house build in Germany, i’m currently trying to figure out exactly which alarm sensors I should get for our electrician to wire in and need some advice.
I am planning to use Konnected to interface the alarm sensors with Smartthings but obviously rather than the way Konnected is designed to be used, to replace the alarm control panel of an existing alarm system, I intend to build a new install based around the Konnected board and purchase all the alarm sensors that I need to connect to it. I have already checked the documentation on the Konnected website but unfortunately this refers to alarm systems available in the US. Living in Germany, what I really need to know is which alarm sensors I should get that will work with Konnected and are for the EU market.
So far I have the following:
Door / Window contact sensors - These came ready fitted to all our new doors and windows and are designed to be connected to an alarm system so in theory they should work with Konnected. However as I understood it, these sensors don’t require power so should only have 2 wires but ours have 4 and in some cases 6 which I am confused about.
Motion Sensors - Would like a couple of interior 360 deg sensors for automatic light control in a few rooms in the house, and exterior sensors for activating lights at night for security purposes. Should I be looking for 12V DC sensors or 230V ones? Or should I not bother at all connecting motion sensors to Konnected just for light control and instead use occupancy sensors that can directly switch the power to the lights with a relay for Smartthings?
Smoke Detectors - As far as I understand it these need to be both hard wired and also have their own backup batteries. They should also have their own built in siren and have the option that when one is activated, it activates all the other detectors in the house. Are there any like this that are designed to work with a wired alarm system for the EU market? All I can find are smart smoke detectors that come with their own app. Also should they be 12V DC or 230V?
Alarm Siren - As I understand it I need a 12V DC alarm siren that doesn’t exceed 1.4A or 15W. Any recommendations on a good one to use?
For any suggestions pointing me the right direction or what to look for I would be very grateful!
