1.3. Working conditions
Exact damper function is provided under the following
conditions:
a)
maximum air velocity 15m/s
b)
underpressure max. -1500Pa or overpressure
max. 500Pa.
Dampers can be installed in arbitrary position (horizontal
or vertical blade axis).
Dampers are designed for macroclimatic areas with mild
climate according to EN60 721-3-3. Temperature in the
place of installation is permitted to range from -30°C to
+50°C.
1.4.
The duck can be ended by grilles. During grilles instal-
lation blade overlaps has to be respected see chapter 3.
Tab. 1.2.1. Classification of Dampers
1. Description
Smoke control dampers - multi are shutters in the smoke
exhaust piping systems. The dampers are designed to
remove heat and combustible products (e.g. smoke) from
effected fire compartments. In the event of fire the Smoke
and Fire ventilation system opens the damper in the
affected section and removes combustion products and
heat from this section.
The damper blade is controlled by electrical actuating
mechanism.
Dampers are fire resistant and are intended for sys-
tems with manual or automatic activation. Dampers are
designed for using in fire compartments that can be con-
nected to the smoke exhaust ducts (tested according to
EN1366-8) or they can be installed in or on the construc-
tion of the fire compartment.
Dampers can be delivered with or without flanges.
