building system


Arcturus system solutions are available to help equipment manufacturers meet the specialized requirements of building system applications including:

  • Public address (PA) systems and mass notification
  • Fire and alarm panel audio controllers
  • School paging systems, campus wide notification
  • Elevator call buttons and rescue assistance
  • Building access controllers and entrance systems
  • Digital intercoms and push-to-call (PTC) devices

Arcturus system solutions offer tools that can help meet or exceed NEMA SB50, SB40 and NFPA-72 digital voice recommendations while providing facilities for highly supervised operation and management from central stations. The system supports options to address audio intelligibility, installer and maintenance tools and provides multiple connectivity options for physical integration to external equipment.



Solutions include installation-ready hardware platforms, bundled with specialized middleware packages suitable for virtually any building system application that combines voice support with supervision or external device integration. In addition to high-quality, two-way intercom support the solution offers scalable multicast PA paging for local or wide-area mass notification. Intelligibility toolkits are available that include ADPCM vocoders, background audio level compensation, pre-recorded announcements and the ability to detect degraded audio performance at the component level. Systems can be operated autonomously, by digital controls or via a network protocol that allows virtualization of the device remotely by a supervising system. Physical interfaces support direct connection of external sensors, door controllers or horns and lights. Solutions are capable of utilizing methods such as IEEE1588 clock synchronization to support the precise trigger events required by external notification equipment such as strobes.
