Smoke extraction damper - SEDM-D
TPM 155/22
I. GENERAL
Description
Smoke extration dampers SEDM-D (hereinafter named also
simply as „the dampers“) are intended to be used in multi
compartment smoke control systems in vertical duct (shaft)
installations.
In normal situation, the dampers remain closed (stand-by
position). Upon an activation signal emitted either in the
event of a fire, or during a functional test, the dampers of
given compartments open in order to allow smoke and heat
from the fire to be extracted outside the building. SEDM-D
dampers open to the inside of the duct. The dampers opened
during functional testing may be put back to the stand-by
(closed) position by hand, or by using an optional electric
rearming motor.
The dampers consist of a single calcium-silicate blade
reinforced by steel crossbeams hanged on spring-equipped
hinges, combined calcium-silicate and aluminum frame, a
cold seal (silicon gasket) and a carbon based thermo-
-expanded hot seal, electrically activated restraint
mechanism equipped by a permanent magnet with an
electric coil, optional with end switches and optional electric
rearming motor, and a metallic grille.
The dampers may be installed to the shaft directly using
fire-resistant mastic, mortar, gypsum or using an optional
installation frame.
