Fire dampers Application - Fire dampers of Type KA-EU for shutting off extract air and exhaust air ducts of commercial kitchens, with general building inspectorate licence - To prevent the propagation of fire and smoke through ductwork to adjacent designated fire compartments Classification - Fire resistance class K90to DIN 4102-6 Variants - With thermal release mechanism - With thermal release mechanism and control module - With electric blade opening actuator and control module Nominal sizes - 250 x 225 to 1200 x 500 mm - L: 595 - 880 mm (depending on the selected casing...

Fire dampers General information Function Construction for manual operation 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. When in the event of a fire the temperature rises to 72 °C, a capillary tube sensor interrupts the power supply to the electromagnet, and the damper blade is released. While power is being supplied to the electromagnets, the fire damper can be opened with the blade opening lever. The release mechanism is accessible and can be tested...

Fire dampers General information Function Construction with electric blade opening actuator Functional description The blade opening actuator is used for the motorised opening of the fire damper; for maintenance and functional tests it can receive signals from the central BMS. When in the event of a fire the temperature rises to 72 °C, a capillary tube sensor interrupts the power supply to the electromagnet, and the damper blade is released. If power is supplied to the blade opening actuator and to the electromagnets, the actuator can move the damper blade into the OPEN position. If the...

Fire dampers KA-EU Design information – Only for use in extract air and exhaust air ducts of commercial kitchens – Fire resistance class K90 can only be achieved with ducts connected on both ends – Ducting must be installed in such a manner that it does not impose any significant loads on the fire damper in the event of a fire. Correct use in solid walls and ceiling slabs Installation location Construction and building material Minimum thickness Fire resistance class Solid walls Solid walls in concrete, aerated concrete 100 or lightweight concrete, gross density ≥ 500 kg/m³ either direction...

Fire dampers Special information – Limit switches Description Application – The fire damper is equipped with two limit switches. – Limit switch for damper blade position CLOSED: This limit switch can be used to indicate the damper blade position. Up to the maximum switch rating, relays or indicator lights for fire alarm systems can be used – Limit switch for damper blade position OPEN: This limit switch is connected with the fan and ensures that the fan runs only while the damper blade is completely open. Technical data Limit switch Connecting cable length/cross section Protection level...

Fire dampers Special information - Electromagnet Description Application Installation information - The electromagnet Type 500-15 - Electromagnets should always be accessible is to be connected to a capillary tube sensor Type TLR-72. - As long as power is supplied to the electromagnet, the magnetic force holds the damper blade open. - If the power supply is interrupted, the magnetic force fails, and the damper blade closes. - As standard, casing widths of B > 600 mm are equipped with 2 electromagnets. Technical data Wiring example - electromagnet CLOSED ® Electromagnet 2 (from width B...

Fire dampers Application - If in the event of a fire the temperature in the extract air duct rises to 72 °C, the capillary tube sensor interrupts the power supply to the electromagnet As a consequence, the damper blade is released and is closed by force of the gas strut or struts. - The capillary tube sensor consists of a protective coil and a flange such that it can be fitted inside the duct - Distance to the fire damper: > 500 mm - Depending on the installation location of the fire damper, several capillary tube sensors may be required - Up to 10 capillary tube sensors can be connected in...
