The BOSEC brand is a specification in itself. The 'as-built' files that must be handed over to you are very precise on the components implemented and on the protocols that govern their subservience between themselves.
These files are therefore very useful, both for maintenance and maintenance, and when further work has to be carried out. During a renovation or extension of the building, the existing installation will not necessarily be called into question because its technical characteristics and therefore its possibilities are known and mastered.
If your maintenance company disappears, make your choice in the list of certified companies to ensure the continuity of your security. A specialized company certified by BOSEC will endorse the work certified by another specialized company certified BOSEC. It will do so only in case of installation in compliance with BOSEC rules.
