Cartridge dampers are designed in accordance with harmonized EN 15650 and certified to comply with the EI-S (EN 1366-2) performance attributes.
PKI-C fire dampers are designed to be embedded into fire partition walls or ceilings (vertical or horizontal supporting construction) into transversal duct, or at the end of a duct in front of the valve.
Installation of these devices is described in the Installation, Operation and Maintenance of the Cartridge Fire Dampers manual.
As a standard, all the dampers are supplied in a basic version or with a microswitch, or accessories – cover plates, or with flexible duct coupling.
The fire damper automatically sets itself to a „CLOSE“ position if the thermal fuse link gets ruptured.
After the closure, the damper blade is mechanically secured in the closed position and can only be opened manually, which requires access of the maintenance staff into the duct.
To improve the duct accessibility for fire damper inspection purposes, we supply a flexible duct coupling as an accessory – labelled as TVKC in the Ordering Codes section.
The thermal fuse link releases the coupling mechanism when the air temperature in the damper exceeds 72°C.
EACH CARTRIDGE FIRE DAMPER MUST BE INSTALLED ACCORDING TO INSTALLATION MANUAL
