Checklist for Installers - Part 3: Is my installation secure?

August 31, 2017

Step-by-Step Project Management – Is your installation safe against unauthorised access?
























Fort Knox, the Tower of London, and the safest of banks and not to forget casinos – Once something is in there, no unauthorised person can get anything out of there. Is that so? Well, most of the times this is the case, but not, when someone forgot to lock the door. And this brings us already to the moral of this little anecdote: No matter how great and secure your safe is, as long as you do not take care of the most obvious security measures, your little or big treasures will never be safe.


Although this article is not about crown jewels, gold or bundles of money, this article addresses something that some might consider of higher importance – Security in your installation against unauthorised access.

Either during your planning or as a check afterwards, the following questions, should be answered positively in order for your customer to have a good-night sleep and for you to be proud of your installation. So, ask yourself:

  • Are devices and applications fixed mounted?

  • Is it ensured that devices are properly protected against dismounting (e. g. use of anti-theft protection measures)?

  • Is it ensured that unauthorized persons have limited access to distribution boards with mounted KNX installations (e. g. always locked or located in locked rooms)?

  • Is it difficult to access devices in external areas (e. g. mounted at a sufficient height)?

  • In case the KNX installation can be operated from areas in buildings that are public and not surveyed, did you contemplate the use of binary inputs (mounted in distribution boards) or push button interfaces?

If you can confidently say that you have taken
