DIVA
  • General
  • Feature
  • Specification
The DIVA8M module unit houses: audio digital signal processing (DSP), a matrix, a digital message player, a fully monitored fireman microphone, amplifiers monitoring with switchover to backup amplifier and loudspeaker lines monitoring. It can process and route one PSSxxDT security microphone console or up to eight cascaded PSM paging microphones and two 0 dB audio plus one Mic/Line inputs into 2 different channels (Music + Voice). Each input is fitted with volume controls and equalizers. All audio inputs feature contact and VOX activation (ideal when using the cordless microphone, for example). Up to 45 minutes of digital messages can be downloaded and recorded as WAV files directly from a computer into DIVA8M. Two messages can be played simultaneously in different zones. One of the messages can be used as a chime for the PSS microphone. Nine monitored evacuation inputs making it possible to obtain the pre-programmed routings. Each DIVA module has eight output zones with a+b wiring. Each zone can be routed manually or automatically to one of the system’s audio channels (Music and Voice). The number of zones can be extended up to 128 zones with DIVA8MS slave module. The two Music signals can be switched ON/OFF in each zone separately. In case of Evacuation, the Music channel can be used as a second alarm channel. A DIVA system requires only one 2 channel amplifier (one for Music, one for Voice). The Music amplifier will act as a backup amplifier in case of the Voice amplifier failure. Each channel can handel up to 500 W of audio power (100 V).
  • 5 audio inputs (2 x line, 1x MIC/line, 1 x PSS or PSM,1 Fire Mic.).
  • Integrated and monitored Fireman microphone.
  • Monitoring of 8 Loudspeaker zones (a+b).
  • Full monitoring of PSS and PSM microphone consoles.
  • Digital message players up to 45 min.
  • Parametric equalization: 3 bands on inputs, 7 bandson the two outputs channels.
  • Low and high pass filtering on inputs.
  • 21 priority levels
  • 4 user levels
  • 8 logic input contacts.
  • 9 evacuation input contacts (with surveillance).
  • 2 fault input contacts
  • 8 output relay contacts.
  • Incident data record with up to 2047 incidents.
  • Possibility to store the event log file on a computer.
  • Internal scheduler.
