    KOOLCOM KOOLCOM fire damper monitoring system. Introduction KOOLCOM is an electronic control system for fire dampers that allows the condition and functionality of each fire damper to be periodically and automatically monitored and checked. It can also close the dampers should the fire alarm be activated.

  • Page 13 The KHUK is a Modbus hub device that occupies a single address, allows up to 128 fire dampers and 128 smoke detectors (32 DCU-4CH units) to be managed. Each KHUK has: - 1 connection to the Koolcom console. - Direct connection to fire panel: • Alarm activation input.
  • Page 14 KOOLCOM System components. Graphic console The KOOLCOM graphic console allows monitoring and control of DCUs connected to the associated KHUK, facilitating the monitoring and control of fire dampers and smoke detectors (zones). The console allows information on the overall status of the system and each connected DCU to be displayed, as well as the basic parameters to be configured and managed.

    KOOLCOM KHUK connection schematic One KHUK has connections for up to 32 DCUs (maximum 128 dampers and 128 detectors), the wall mounted graphic console and a BMS. It can interact with the central fire alarm system with external alarms going to the KHUK and detected alarm coming from the KHUK.
  • Page 16 KOOLCOM KHUK AND DCUs Three wires with polarity that connect exclusively to the DCUs. The KHUK contains the MODBUS termination. By inserting the MBUS TERM bridge into the furthest DCU, the two necessary terminations are achieved. Different DCU models (DCU- 1CH and DCU-4CH) can be mixed in the same bus.
