Fire dampers are shutters in ducts of air-conditioning devices that prevent spreading
the fire and combustion products from one fire segment to the other one by means
of closing the duct in the points of fire separating constructions.
Dampers blade automatically closes air duct using a shutting spring or
an actuating mechanism back spring. Closing spring is released either by pushing
of the button or by thermal fuse.The back spring of the actuating mechanism is started
when the thermoelectrical starting mechanism BAT is activated, when a reset button on
BAT is pushed or when a power supply of the actuating mechanism is stopped.
The fire damper is sealed with a silicon packing against smoke penetration after
closing the blade. At the same time, the damper blade is bedded in a material which
enlarges its capacity and air proofs the air duct.
