Unfortunately, there are so many fire alarm systems in our country that do not fulfill their functions and have become inoperable for various reasons. It is very difficult to fortify these systems, to rewire them, even if they differ from facility to facility. Retrofit applications stand out for facilities with this structure.
If the need arises to define the retrofit application, we can briefly express the operation of the new system to be newly installed through this old cable infrastructure by using the existing cable infrastructure.
Since there is no detailed information about the old cable infrastructure, care should be taken to select the new system to be preferred.
It is of great importance to use fire alarm systems in which the communication protocol does not depend on the cable type, which are capable of operating with every type of cable and which have high standing power in order to avoid the recurrence of the same problems.
