Functional description
In the event of a fire, fire dampers shut automatically to prevent the propagation of fire and smoke through ductwork to adjacent designated fire compartments. In the event of a fire, the damper is triggered at 72 °C or at 95 °C (use in warm air ventilation systems) by a fusible link. The release mechanism is accessible and can be tested from the outside.
Construction with spring return actuatorFunctional description
The spring return actuator enables the motorised opening and closing of the damper blade; it can be activated by the central BMS. In the event of a fire, the damper is triggered thermoelectrically at 72 °C or 95 °C (use in warm air ventilation systems). As long as power is supplied to the actuator, the damper blade remains open. If the supply voltage fails, the damper closes (power off to close). Motorised fire dampers can be used to shut off ducts. The torque of each actuator is sufficient to open and close the damper blade even while the fan is running. The spring return actuator is fitted with limit switches that can be used for capturing the damper blade position.
Construction with spring return actuator, explosion-proofFunctional description
The fire damper is used as a shut-off device to prevent fire and smoke from spreading through ducting in areas with potentially explosive atmospheres. The fire damper is suitable for supply air and extract air systems in potentially explosive atmospheres. For the operation of the fire damper, the operating and installation manual and the technical data in the supplementary operating manual must be observed.
Air transfer damperFunctional description
Air transfer dampers are designed to shut off openings for air transfer in fire resistant internal walls and ceiling slabs. To prevent smoke from spreading in buildings, it is extremely important that the smoke is detected at an early stage. Duct smoke detector Type RM-O-3-D is required to control and trigger the air transfer damper. The smoke detector operates on the principle of light scattering and detects the smoke regardless of its temperature so that the fire dampers can be closed before the release temperature is reached. The thermoelectric release mechanism of the spring return actuator also triggers the closure of the damper blade. When the release temperature (72 °C) is reached, the temperature sensor in the airflow interrupts the supply voltage to the spring return actuator. The spring return in the actuator causes the fire damper to close (power off to close). A second temperature sensor monitors the ambient temperature. If the supply voltage fails, the damper closes. Air transfer dampers consist of an FK-EU fire damper, an RM-O-3-D duct smoke detector with general building inspectorate licence Z-78.6-125, a spring return actuator (24 V AC/DC or 230 V AC) with two integral limit switches, and cover grilles on both ends.
