Motor-driven fire damper monitoring systems – KOOLCOM - 3

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. While this system is capable of being managed by a BMS (Building Management System) system, KOOLCOM can also work in Standalone mode, i.e., operate autonomously without the need for a BMS or any external maintenance personnel. Graphic console KOOLCOM is the only system on the market whose...

System components. Damper Control Unit (DCU 1CH) The DCU contains the control electronics for the different fire dampers. KOOLCOM offers two models which allow either 1, or up to 4 dampers to be controlled by the same device. DAMPER CONTROL UNIT 1 CHANNEL (DCU 1CH) DCU 1CH (Damper Control Unit, 1 Channel) are devices used to send commands and supervise motorised fire dampers, which by means of commands sent through the ModBus allow them to be automated and controlled. They are integrated in the KOOLCOM fire damper control and supervision system. This system is completed with KHUK units...
