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 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...
