II. GENERAL INFORMATION
1. Description
1.1.
Fire dampers are shutters in piping systems 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
air piping in the points of fire separating constructions.
1.2.
Basic dampers parameters
- fire damper tests provided according to EN 1366-2 and EN 15650.
- fire damper classified according to EN 13501-3 + A1 as
EI 90 (ve ho i
- casing (external) leakage classified as class C according to EN 1751
- closed blade (internal) leakage classified as class 2 according to EN 1751
- fulfil all the prescribed requirements of EN 15650, art. 4.2.2. Protection against corrosion
- dampers are classified as C10000 (cycling test) according to EN 15650
1.3.
Dampers blade automatically closes air duct using a shutting spring or an actuating mechanism
back spring. The back spring of the actuating mechanism is started when the thermoelectrical
starting mechanism BAE 72B-S is activated, when a reset button on BAE 72B-S is pushed or
when a power supply of the actuating mechanism is stopped.
1.4.
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.
1.5.
Operation of the dampers does not depend on the direction of air circulation. The dampers can
be located in an arbitrary position.
1.6.
Dampers have one inspection hole, since the shutting device and the inspection hole can be set
into the most advantageous position (with respect to the operation and manipulation with the
control device).
1.7.
Exact damper function is provided under the following conditions:
a) Maximum air circulation speed: 12 m.s
Maximum pressure difference: 1500 Pa
b) Dampers could be displaced into position "CLOSED" only in case that ventilator, or Air
Handling Unit is switched off. The goal is the securing of proper closing and safe
function of Fire Damper in case of Fire.
c) The air circulation in the whole damper section must be secured as steady on whole
surface.
1.8.
Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3.
1.9.
Dampers are suitable for systems without abrasive, chemical and adhesive particles.
1.10.
Temperature in the place of installation is permitted to range from - 20°C to + 50°C.
1.11.
If is not noticed other way, all dimensions and weight are in millimeters and kilograms.
1.12.
