This means, digital technology has been combined with conventional analogue 100V technology. The system consists of a VAB1 controller and matrix, line managers, amplifiers, and speakers to form a simple but secure and stable PA application. BOC uses the new PA system mainly to supply background music to the corridors at the Governor's office, but also for voice evacuation purposes. Therefore, the VAB1 controller is equipped with an EVAC expansion card to fulfil evacuation requirements, and to ensure highest security in the facility.
The existing fire detection system has been linked into the Varizone VAB-Line. Additionally, it offers interfaces to other third-party systems for joint control, building management, fire and information release systems.
"The BOC, with its branches and institutions, spreads throughout the building, and has very high security requirements", says Tony Chen, Wincom's president. "That is why we strongly recommended installing Varizone, a PA system offering the highest reliability and stability. The striking benefit finally was Varizone's ability to unify digital and 100V technology under the same roof."
