Smoke extraction dampers - MSD are designed into an inlet or
extract smoke ventilation system. The dampers are designed either
to close to provide compartmentalization or to open (for fresh air
inlet) or to allow removal of the heat and combustible products from
a fire in the affected fire zone/compartment.
The damper blade is controlled by electrical actuating mechanism.
Dampers are fire resistant and are intended for systems with
automatic activation.
Dampers are designed for using in fire compartments that can be
connected to the smoke exhaust ducts (tested according to EN
1366-8) or they can be installed in or on the construction of the fire
compartment. Damper MSD

Design
Design with actuating mechanism
■Belimo actuators are used for dampers, series BEN, BEE,
BE for 230V AC resp. 24 V AC/DC, Schischek InMax 50.75-S
actuators (universal 24V or 230V supply) are used for
large size of dampers.
■After connection to the power supply voltage, the
actuator moves the damper blade to the "OPEN" position
or "CLOSED" (according to the corresponding connection,
see wiring diagram). If the power supply is interrupted,
the actuator stops at the current position. The signalling
of the "OPEN" and "CLOSED" damper blade positions is
ensured by two built-in fixed “potential-free” end- limit
switches.
■The actuator for operating the damper blade is mounted
in an insulated cover/box. It is accessible after removing
the cover lid. The electrical connection of the actuator is
made with a non-flammable cable (or a cable located in
the adjoining cable duct), which passes through an
opening made in the wall of the insulated cover/box when
installing the damper or when connecting the actuator
power cable. The power and control cable must be CAT 3
as BS EN8519.
Design .44 and .54
■Belimo modulating actuators, BEN (BEE)-SR series for 24V
AC/DC are specially designed for remote control of fire
dampers. The position of the damper blade is adjustable
by means of control voltage 0 (2)...10V DC.
■The signalling of the "OPEN" and "CLOSED" damper blade
positions is ensured by two built-in fixed “potential-free”
limit switches.

TPM 159/22
Placement and Assembly
■Smoke dampers are intended for use in spaces with
multiple fire compartments, which can be connected by a
smoke extraction duct tested according to EN 1366-8 or
EN 1366-9 or can be installed in the construction of the
fire compartment.
■Dampers can be installed with the actuator on the top,
bottom or either side.
■If Actuator is installed on the bottom take care when
removing the actuator housing cover.
■To provide needed access space to the control device, all
other objects must be situated at least 350 mm from the
control parts of the damper.
The distance between the smoke damper and the construction
■minimum distance 200 mm between dampers installed in the duct;
■minimum distance 75 mm between damper and construction (wall/ceiling).
■This is the EN 1366-10 test standard distances. They are
considered as minimum. Actual location should be
based on wall manufacturers requirements.
■Always consult the wall manufacturers specific guide-
lines for deflection heads, penetration size, location to
other services, fire stopping and load bearing capacity.
■With smoke control ducting then refer to duct manu-
facturers tested parameters for spacing & pattress re-
quirements.
■No other services should pass through the dampers
building work opening.
■For lightweight walls always consult the wall manufac-
turer specific guidelines for penetrations sizes and dis-
tances.
■During installation the damper blade must be in position
“CLOSED”. The damper body should not be deformed in
the course of installation.
■Once the damper is built in, its blade should move freely
and not rub against the body of the damper or duct during
operation.

Built in edge
"Wall edge sticker" indicates the recommended edge of installation
of fire damper into the fire partition structure (wall).
The damper must be installed so that the entire damper blade - in
the closed position - is located inside the fire separating structure
(wall) and at the same time the control mechanism and inspection
openings are freely accessible.
