As standard, all fire dampers are designed and certified to comply with EI-S performance attributes. PK-I fire dampers are intended to be embedded into fire partition walls. Installation of these units is described in the Installation, Operation and Maintenance manual for square and circular fire dampers. As standard, all dampers can be supplied with a manual actuator, optional accessories, e.g. microswitches, electromagnets, or a servo-driven actuator and communication control units. Detailed description regarding individual models can be found in TPI-28_PKIR_PKIS_EN_201403.pdf
Fire Dampers With a Manual Actuator
Fire damper automatically sets itself to closed position if the thermal fuse link gets ruptured or by means of the electromagnet. After the closure, the damper blade is mechanically secured in the closed position and can only be opened manually. The fast blow fuse releases the link mechanism as soon as the air temperature in the duct system reaches 74 °C.
Fire damper casings are made of galvanized steel sheets and the blades are made of calcium silicate boards (asbetstos free).
ZV to DV1-2 - stands for manual actuating mechanism
DV3 to DV5D-2 - stands for actuating mechanism with electromagnet
Detail see in TPI-28_PKIR_PKIS_EN_201403.pdf

Fire dampers can be installed into rigid or flexible fire safe partition walls and ceilings and are connected directly to the duct.
