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 TPI28_PKI-R_S_EN.pdf.
Fire Dampers With a Manual Actuator
Fire damper automatically sets itself to closed position if the thermal fuse link gets ruptured or a signal is given to the electromagnet to release the damper blade from an open to closed position. 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 72 °C. The damper can also be closed electronically by receiving a signal from the building's control system, provided that the damper is equipped with an actuating electromagnet for this purpose.
The function of the fire damper is to stop the spread of fire, flames and smoke.
Fire damper casings are made of galvanized steel sheets and the blades are made of calcium silicate boards (asbetstos free). Each fire damper has a mechanism, manual or with electro-magnetic release.
ZV to DV2-2 - stands for manual actuating mechanism
DV3 to DV6-2 - stands for actuating mechanism with electromagnet

COVER PLATES ARE OBLIGATORY FOR DRY INSTALLATION!
Fire dampers can be installed into rigid or flexible fire safe partition walls and ceilings - (details see in TPI28_PKI-R_S_EN.pdf in Dokumentation tab) - and are connected directly to the duct.
EACH FIRE DAMPER MUST BE INSTALLED ACCORDING TO INSTALLATION MANUAL!
