Type KA2-EU fire dampers close off extract air and exhaust air ducts in commercial kitchens and prevent the spread of fire and smoke via air ducts into adjacent fire compartments. In standard operation, the fire damper is in the Open position. This is made possible by the electrically operated spring return actuator, which enables the motorised opening of fire damper. The spring return actuator also enables the fire damper to be activated by the management and control equipment (MCE) during maintenance work and functional checks. In the event of a fire, one of the two thermoelectric release units is triggered. From a trigger temperature of 72 °C, the damper blade closes the fire damper within 3 seconds. In addition, an interruption in the supply voltage also causes the fire damper to close. The closing process is based on the fail-safe principle. The control system of the spring return actuator differentiates between a fire and other interruptions. The limit switch signal can also be used to close other KA2-EU units. The signal on leaving the Open end position can be used to switch off the supply voltage to other fire dampers. Fire dampers that are further away from the fire then close within 10 seconds. TROXNETCOM offers further solutions. Limit switches can be used for position indication. When leaving the Open position, the signal from the Open limit switch must be used to switch off the fan.
