® NORDfire | FDMQ 1. General 1.1 Description Fire dampers are shutters in ducts of air-conditioning devices that prevent the spread of fire and combustion products from one fire segment to the other one by means of closing the duct in the points of fire separating constructions.
® NORDfire | FDMQ 1.3 Working conditions Exact damper function is provided under the following conditions: • maximum air circulation speed: 12 m/s • maximum pressure difference: 1200 Pa • the air circulation in the whole damper section must be secured steady over the entire surface. Dampers can be installed in arbitrary position.

® NORDfire | FDMQ 2.2 Design with spring return actuator Design .40 and .50 The fire dampers are equipped with Belimo spring return actuators with thermoelectric activation device BAT. The spring return actuator types are BFL, BFN or BF depending on the damper size. (Further mentioned as „actuator“).
Page 10
® NORDfire | FDMQ Thermoelectric activation device BAT If the thermal fuse Tf1 is interrupted (due to temperature outside the duct), it is necessary to replace the spring return actuator. Thermoelectric activation device BAT is integral part of the actuator. If the thermal fuse Tf2 is interrupted (due to temperature inside the duct), only the spare part ZBAT 72 (95/120/140) needs to be replaced (acc.to the activation temperature).
® NORDfire | FDMQ 3. Material, dimensions, weights and effective area 3.1 Material Damper casings are made from galvanized sheet metal without further surface treatment. Damper blades are made from fire resistant asbestos free boards made of mineral fibres. Manual control have cover made of mechanically resistant and durable plastic and the other parts are galvanized without further surface treatment.
