PDFDTI 2000 Manual (pdf)

The DTI 2000 is a micro processor-controlled, completely configurable telephone interface for the Dynacord ProAnnounce system. The DTI 2000 is used for connecting the DPM 4000 System Manager to a telephone line or network to launch announcements from each telephone set over the loudspeaker network and to trigger signals, pre-recorded text messages and control functions (macros) of the DPM 4000 System Manager using a telephone set. The DTI 2000 is connected to an analog phone line and is controlled via tone-dial (multi-frequency dialing). Using the supplied cable, the telephone interface has to be connected to a paging console input on the DPM 4000. The interface transmits serial control data as well as LF-audio signals. The DTI 2000 appears at the DPM 4000 as a special paging console allowing it to be programmed via the PC Designer Software in paging console dialog mode.

The DTI 2000 offers 100 call numbers (from 00 to 99). Any function can be assigned to any call number. Possible functions include zone or group selection, live-announcements with preprogrammable priority and pre-chime signal, playback of pre-recorded text messages and triggering of DPM 4000 macros. The DTI 2000 offers two different access levels with individual password protection. Depending on the actual application and desired operation, the DTI 2000 allows initiating any possible function from a standard telephone set - from making a simple announcement up to triggering a sound reinforcement installation’s most complex sequential control procedures.


  • Selection of up to 100 zones for announcements
  • Programming of up to 20 call groups for group calls and collective calls
  • Configuration of a call number chart of up to 100 numbers
  • Selecting several zones or groups for announcements
  • Initiating the playback of pre-recorded text messages
  • Triggering of special functions (macros, erase zone / group selection)
  • Assigning priorities for announcements and message playback

  • Automatic hang up: to specify the duration of announcements via internal Dip switches
  • Trimmer on the front panel for setting the audio signal level
  • Programming via ProAnnounce Designer Software equivalent to DPC4000 paging consoles
  • Configuration possibility for world telephone standards (country-specific settings)
