KT-300 combus modules

Five Combus modules can be connected to a KT-300:

  • KT-PC4108 (8-zone input expansion module). This module has a tamper contact input.
  • KT-PC4116 (16-zone input expansion module). This module has a tamper contact input.
  • KT-PC4204 (4-relay/power supply expansion module). It has a tamper contact input and also includes a built-in 12VDC, 1A power supply for field devices.
  • KT-PC4216 (16-zone output expansion module). It can be used for elevator control, although additional hardware may be required.
  • KT-LCD3 (Kantech 32-character liquid crystal display). The LCD is green (normal status), red (power failure) and yellow (trouble).
  1. If a Combus module is installed to the KT-300 controller, click the Combus module configuration button. Undefined Combus terminals are identified by red flags/bullets. Once a module has been defined, it is identified by a green flag.
  2. To define a module, select one, then click the Define button (lower part of the window). The Enter Combus module serial number message box appears.
  3. Enter the module’s serial number, then click OK.
    Note: To obtain this number, you have to activate the Tamper switch or to press any key on the keyboard. The Combus serial number is displayed in the Desktop Message.
  4. Assign names to the modules in the language fields.
  5. Check the options related to the module you want to configure (if these are displayed in the window).
    Note: Usage options of a module vary according to the selected Combus module. For example, installing the KT3-LCD and checking the options Combus low power and Display date and time will allow the KT-300 to report Combus low power conditions and to display the date and time.
    Table 1. The options associated with each module
    Combus type Options Additional options
    KT3-LCD Combus low power, display date and time No additional options
    KT-PC4108 Tamper alarm, Combus low power 8-input module
    KT-PC4116 Tamper alarm, Combus low power 16-input module
    KT-PC4204 Tamper alarm, Combus low power, Low battery, Power failure, lower auxiliary power Used as relays (1-4)
    KT-PC4216 Tamper alarm, Combus low power Used as outputs
  6. Check the Combus low power option so that the KT-300 will report any Combus low power condition.
  7. Check Display date and time option so that LCD can display the date and time.
  8. When you have finished configuring the Combus module, click the OK button to go back to the Status relay tab.
  9. Associate a Local activation relay for Power failure, Combus failure and Combus low power (multi-site Gateway only). If you want to assign a specific relay, you may click the three-dot button and select a specific relay or group of relays.
    Note: To configure local activation relay, you must configure relays (Devices > Relays), and then select specific relays for local activation.
  10. Under Priority call type, assign the call type option that best suits failure event reporting (multi-site Gateway only). To access the Priority call type feature, the site connection type must be set to Modem.
