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.
SEDM-D dampers are characterized by
■Zero power consumption in stand-by position
■Instant opening and fast closing
■Small built-in dimensions
■Light design of high fire and pressure resistance
■Large effective area
■Room protected from moving parts
■Wide range of damper dimensions
■Wide range of colours available
■Easy installation also into thin shaftwall materials
■Availability of spare parts

Operating conditions
Both declared performance and faultless operation are ensured under the following conditions:
■The damper equipped with one of the grilles available
■Maximum vacuum up to 1500 Pa or overpressure up to 500 Pa
■Rearming shall be carried out without air flow and without air pressure
■The dampers are suitable for vertical installation only
■Range of activation voltage and rearming motor supply voltage shall be respected; dimensioning of voltage sources and of
connecting cables shall fit the electrical parameters of the damper
■Connecting cables shall not physically impede free movement of moving parts and sub-asemblies
■Damper shall be always kept closed with the exception of short periods of installation, commissioning and functional tests
■The rearming motor shall not be used to act against the air pressure or another external force
■Dampers are designed for macroclimatic areas with mild climate according to EN IEC 60 721-3-3 ed.2., class 3K22.
(Environment 3K22 is typically protected place with regulated temperature) and with a temperature range of -25°C to 50°C
Connecting cables shall be guided from a pre-punched hole in
one of the corners of the damper frame to the junction box
using delivered cable clips. The junction box contains a
universal 10-position screw terminal. Damper supply voltage
and terminal block positions are printed inside the junction
box. Depending on the damper design configuration and
connecting cables available, some terminal positions may
stay void. Aditional junction box with 6-position screw
terminal is present for bipolar end-switch module.
The damper is equipped with a restraint mechanism keeping
the damper closed. The restraint mechanism includes a
permanent magnet combined with an electric coil with
magnetic poles opposite to those of the permanent magnet.
In case of the activation of the damper, the coil magnetic field
compensates the magnetic field of the magnet and thus, the
restraint mechanism lets the damper open. The activation
signal represents a simple switching the voltage ON. The
damper may be equipped with position end-switch module
with end-switches indicating the damper blade position open
or closed. The damper is manufactured in hand-operated
rearming design or electric motor rearming design. Rearming
means getting the damper blade from the position open
(security) to the position closed (stand-by).
