Rectangular wall mounted fire damper Optimized rectangular wall-mounted re damper with a re resistance up to 120 minutes. CU-LT-1s combines the energy efciency of our range of optimized dampers (minimum pressure loss, small dimensions) with the ease and speed of a dry assembly. Easy to mount and light in weight, CU-LT-1s is the ideal solution for renovation projects and, in general, for building sites where access to the damper is difcult or impossible from one of the wall sides (terminal damper). The re damper can be equipped with a fusible link mechanism up to a motorized mechanism. • • •...

Rectangular wall mounted fire damper MMAG: upgradable automatic / remote controlled operating mechanism with fusible link The operating mechanism MMAG automatically unlocks the blade when the temperature in the duct exceeds 72°C by sending an electrical impulse (VD) or a by interrupting the power supply (VM) to the magnet. Manual or motorized rearmation (ME MMAG). Standard: • Fusible link 72° C • Manual unlocking possible • Manual rearmation, use a rearmation handle (turn clockwise) • IP42 • Remote controlled by means of a dual voltage magnet 24/48V Types of magnets: • VD = natural magnet •...

Rectangular fire damper If the height < 200mm the mechanisms MFUSP and MMAG are turned 90° for the assembly. Height < 200mm An inspection shutter can be used to visualise the position and the condition (e.g. lth) of the damper. The inspection shutter is always mounted by two-fold, one on the lower side and one on the upper side of the re damper (the accessible side is still unknown before the installation). Round connection on a rectangular damper • Connection to ducts with 20 mm anges ( and 30 mm anges) • Connection of damper/duct: - either with sliding prole (anges of 20 mm only) - or...

Rectangular wall mounted fire damper As the re damper is a safety element it needs to be stored and handled with caution. • Avoid any kind of damage • Avoid contact with water • Avoid deformation of the casing during the installation and sealing to unload in a dry area to avoid heavy shocks not to rotate the damper while moving it not to use the damper as a scaffold, working table, etc. not to store smaller dampers inside larger ones The damper can be mounted with the axis horizontally or vertically The damper has to be installed in conformity with the test report Avoid obstruction of...
