The card is part of the MULTIVES Voice Alarm System (DSO). It is versatile and gives the opportunity to apply the solution in many types of objects allow you to adapt to the needs of the investor. The system perfectly fulfills its role both in central architecture in medium-sized buildings, as well as in the largest projects with dispersed architecture, such as shopping centers, refineries and office buildings.
Thanks to the modular and flexible design of DSO system control units, it is possible to optimize designs in terms of hardware and thus reduce the costs of using the entire system.
