The TD-Z Series is a multi-channel, selective-call intercom system with communication privacy when the CT-Z central terminal board is used. 6-call (TD-6Z) and 12-call (TD-12Z) master stations are available and a complete TD-12Z system can handle up to 6 conversations simultaneously! Just simply pick up the handset, select a number, push the CALL-button to call and communicate when another party replies. The system uses a simple home run wiring that runs from each station connecting to the central terminal board and uses paralleled wiring when a central terminal board is not used. Up to 2 door stations can be installed with door release function through DE-UR door station adapter. The TD-Z master stations are primarily designed for wall mounting, with the use of TDW terminal boxes with 1.5m cords; they can be turned into desktop handsets.


  • Privacy intercom system with full trunkage communication
  • 6- and 12-station handsets with maximum capacity of 7 or 13 stations
  • Homerun wiring to CT-Z terminal board, parallel wiring without terminal used
  • Optional paging zones (in place of handset station)
