1.1.
Fire dampers are shutters in ducts 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 duct in the
points of fire separating constructions.
Dampers blade automatically closes air duct using a shutting spring or an actuating mechanism
back spring. The shutting spring is started by releasing an initiation lever. The impulse for
releasing the lever can be either a manual one, a thermal one or an electromagnetic one. 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.
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.
Square dampers have two inspection holes. Round 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).
1.3.
Working conditions
Right damper function is secured under the following conditions:
a) Maximum air circulation speed: 12 m.s
Maximum pressure difference: 1200 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.
Operation of the dampers does not depend on the direction of air circulation. The dampers can
be located in an arbitrary position.
Dampers are suitable for systems without abrasive, chemical and adhesive particles.
Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3.
Temperature in the place of installation is permitted to range from - 20°C to + 50°C.
