BSK...1A  Normally open fire-resisting duct damper with a thermal fuse and a return spring.

 

BSK...PKPBSK...PVPBSK...PSPNormally open fire-resisting duct damper with an electric actuator, a return spring and a thermoelectric breaker.

 
USE

A fire safety damper prevents the spread of smoke and fire via ventilation and air conditioning system ducts in the event of fire.Such units are installed in air ducts located in fire-separation walls and ceilings. The fire resistance rating according to EN 1366-2 is EIS 60 or EIS 120.

DESIGN

The BSK series dampers are made in the general-purpose industrial version with a minimized variety of hardware components using lowalloy galvanized steel. The flap is made of fire-resistant material (vermiculite) with thermoexpansive fireproof sealing. The duct design implies two connection ports for integration into a ventilation duct (duct system).

CONTROL AND MODIFICATIONS

Depending on the design variant the BSK series dampers are equipped with:

MECHANICAL ACTUATING UNIT WITH A THERMAL FUSE AND A RETURN SPRING The fire safety damper remains open in the protective position. The damper is set to the operating position upon the thermal fuse breakdown resulting from a temperature increase. In the event of fire, the fusible element will melt upon the temperature reaching 72 °C and the spring will set the flap to the closed position.

ELECTRIC ACTUATOR WITH A BUILT-IN RETURN SPRING AND A THERMALLY SENSITIVE BREAKER Setting the damper to operating position (direct fire contact): remotely, via electric actuator. The damper can be set to the operating or protective position either remotely via a control panel or manually using the manual cocking handle which is always included in the standard delivery set of the electric actuator. In case of the remote control panel failure, the back-up thermal breaker interrupts the power supply to the electric actuator and the return spring sets the damper to the operating position. Emergency damper actuation: The damper flap is set to the protective position automatically (damper unaffected by fire). The electric actuator remains energized at all times. In case of an emergency actuation (direct fire contact): The electric actuator equipped with a return spring is de-energized and the damper flap is set to the operating position by means of the spring energy. In case of a power failure not related to fire and its subsequent restoration at the actuator with a return spring, the damper flap returns to a protective position.

MOUNTING

During the fire safety damper installation make sure that the release mechanism and the inspection hole face an easily accessible side of the wall or ceiling. This will ensure convenient control of the thermally sensitive release mechanism and its internals. The damper can be embedded into brick or concrete walls with the appropriate fire resistance rating. Wooden spreader bars should be used to avoid casing deformation during the installation.

Use of wooden spreader bars during installation

Upon completing the installation remove the wooden spreader bars.

Recommended damper positions

The damper may not be installed:

  • Into air ducts and on premises rated explosion and fire safety category A and B.
  • Into air ducts of local intakes for flammable and explosive mixtures.
  • Into systems which are do not undergo periodic cleaning pursuant to the established regulations for prevention of flammable deposit buildup.
