The size of the installation hole is 0D + 20 mm. Detailed installation instructions, as well as an installer's installation certificate form, are supplied with each product. WEIGHT (kg) ACCESSORIES AND PRODUCT MODELS The manual fire damper can be equipped with a bipolar limitswitch, MS, which indicates the closing of the shutoff blade. The limitswitch has potential-free points (no = normally open and nc = normally closed), which can be used to control other fire dampers equipped with an electric release, e.g., triggering an alarm in the fire suppression system. The maximum operating voltage...

Solenoid operation The manual fire damper can be released using solenoid, by switching on the solenoid operating voltage. The release can be initiated by e.g. a smoke detector, limitswitch, pressure switch or similar, which connects the power supply via e.g. an auxiliary relay. (design value) Enclosure class (minimum) IP20 IP20 Operating Time Ratio ED 100% 100% Electromagnetic operation The fire damper stays open when the electrical circuit is closed. The fire damper is shut by opening the circuit. Note: Interruption of the power supply closes the damper. Uninterrupted power...

Electric actuator wiring diagram The fire damper is installed on concrete or masonry walls and ceilings and on lightweight walls. An opening is always left in the separating element for the casing of the product to be led through the structure. The maximum diameter of the installation hole is the fire damper diameter D + 20 mm. To make installation easier, all products come with an installation/casting frame, which is used to fasten the fire damper to the wall surface or the steel frame of the plasterboard wall. The installation is finished by filling the casting frame from the front of the...

Servicing A manual fire damper can be reset after the fuse temperature has fallen below the release temperature. If the shutoff blade does not lock, the fuse is worn out and must be replaced. The fuse can be changed from outside the fire damper. The fuse of a fire damper equipped with an electric actuator must be replaced if the fuse has been released because of a rise in temperature. To ensure proper operation of fire dampers, they should be inspected regularly. The minimum recommended inspection period is one year or according to the building code It is recommended that the fire damper is...
