FDMB - Fire damper
TPM 164/22
I. GENERAL
Description
Working conditions
■
Exact damper function is provided under the following conditions
■
maximum air velocity 12 m/s
■
underpressure max. -1200 Pa
■
the air circulation in the whole damper section must be secured as steady on whole surface.
■
Dampers can be installed in position with horizontal or vertical blade axis.
■
Dampers can be installed in position with actuating mechanism on top or on the side of damper.
■
Dampers are suitable for systems without abrasive, chemical and adhesive particles.
■
Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3, class 3K22.
■
Temperature in the place of installation is permitted to range from -30°C to +50°C.
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 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.
Dampers have two inspection holes.
