FDMA

FDMA

The FDMA fire dampers are closures in HVAC systems that prevent the spread of fire and combustion products from one fire compartment to another. The damper blade automatically closes the air duct by means of a spring or a servo drive. The closing spring is actuated by releasing the trigger lever. The impulse to release the trigger lever can be manual, thermal or by means of an electromagnet. The return spring of the servo drive is activated when the BAT thermoelectric starter is activated. After closing the blade, the damper is sealed against the passage of smoke with a silicone seal. At the same time, the damper blade is embedded in a mass, which increases its volume due to the increasing temperature and closes the air duct airtight.

- Declaration of performance No. PM/FDMA/01/20/1
- Hygienic assessment - Report No. 1.6/pos/19/19b

Operating conditions:
Faultless operation of the dampers is ensured under the following conditions:
a) maximum air flow speed of 12 m/s
    maximum pressure difference of 1200 Pa
b) even distribution of the air flow in the entire cross-section of the damper.

CFDM

CFDM

The fire dampers CDFM are closures in ducts of HVAC equipment, which prevent the spread of fire and combustion products from one fire compartment to another by closing the air ducts in the places of installation according to ČSN 73 0872.

FDS

FDS

The FDS rectangular fire damper is designed to divide fire compartments and prevent the spread of toxic gases, smoke and flames. The FDS fire damper is an element of passive fire protection and, together with the method of its installation, is an inseparable part of the evaluation of the fire resistance of a building. The FDS rectangular fire damper is certified according to the ČSN EN 15 560 standard, tested according to ČSN EN 1366-2 and classified for EIS according to the 13501-3+A1 standard. The FDS fire dampers are made of galvanized sheet steel and contain lime-silica parts, fire-resistant carbon fiberglass, polyurethane foam and ethylene-propylene rubber.

F-B90 fire damper with manual operation
The trigger mechanism of the F-B90 fire damper is activated when the ambient air temperature reaches 74 °C. In the event of a fire, the damper closes automatically within 10 seconds after the thermal fuse has melted. Once the damper is closed, the blades remain locked in the closed position and can only be opened manually. On request, the fire dampers can be supplied with limit switches to signal the position of the blades.

F-B90 fire damper with actuator
The F-B90 fire damper with actuator closes on a signal from the building management system (BMS) or when the temperature exceeds the thermoelectric temperature sensor, which is standard on every damper. If the temperature exceeds 72°C, the actuator power circuit is interrupted and the spring closes the damper blades within 20 seconds.
