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.

Types of offered FDS fire dampers 

FDS-3G
Damper with fire resistance up to 120 minutes, the casing is made of one piece. Size range from 100x100 to 1200x800 mm.

FDS-3G-KS
Damper with fire resistance up to 120 minutes equipped with a square installation kit designed for a square installation opening, which is a fixed part of the damper. Size range from 100 to 630 mm.

FDS-3G-OF
Damper with fire resistance up to 120 minutes equipped with protection overflow grille on both sides. Size range from 200x200 to 1200x800 mm.

FDS-EI90S
Damper with fire resistance up to 90 minutes, the casing is composed of two steel parts, conductively connected via a calcium-silicate central frame. Size range wider than 1200 mm and higher than 800 mm, maximum 1600x1000 mm.

FDS-EI120S 
Damper with fire resistance up to 120 minutes, the casing consists of two steel parts, conductively connected via a calcium-silicate center frame. Size range wider than 1200 mm and higher than 800 mm, maximum 1600x1000 mm.

The FDS fire dampers are supplied with manual control or with an actuator.

FDS fire damper with manual control
The FDS fire damper mechanism is activated when the temperature at the fuse reaches 74 °C (100 °C on request). In the event of a fire, the damper closes automatically within 10 seconds after the thermal fuse has blown. When the grille is closed, the grille blades remain locked in the closed position and can only be opened manually.

FDS fire damper with actuator
The FDS fire damper with actuator is equipped with limit switches as standard, optionally with power supply and communication unit. The actuator closes the damper based on a signal from the building management system (power failure) or when the thermoelectric temperature sensor temperature exceeds 72 °C. The actuator supply circuit is interrupted and the spring closes the damper blades within 20 seconds.

Damper activation mechanism with manual control
• H0 
Basic damper design, manual actuation mechanism with return spring and fusible thermal fuse with activation at 74 °C (100 °C on request). The mechanism is equipped with a protection cover IP 44 
• H2 
Manual activation mechanism H0 + indication of open and closed position by two limit switches for 230V AC or 24V AC/DC. The mechanism is equipped with a protective cover IP 44. 
• H5-2 
Manual activation mechanism H0 + activation mechanism with 24V AC/DC electromagnet in pulse connection (activation of damper blade closing occurs by impulse after voltage is applied to the electromagnet) + indication of closed and open position of the damper with two limit switches for 230V AC or 24V AC/DC. The mechanism is equipped with an IP 44 protection cover. 
• H6-2 
Manual activation mechanism H0 + activation mechanism with 230V AC electromagnet in pulse connection (activation of damper blade closing occurs by impulse after voltage is applied to the electromagnet) + indication of closed and open damper position by two limit switches for 230V AC or 24V AC/DC. The mechanism is equipped with an IP 44 protection cover.

Activation mechanism of the dampers controlled by an actuator
• B230T or G230T
Activation mechanism with Belimo (B230T) or Gruner actuator (G 230T) with return spring, further equipped with thermoelectric trigger sensor with activation at 72 °C. The actuator includes two limit switches for signaling the position of the damper blade. Power supply 230V AC.
• B24T or G24T
Activation mechanism with Belimo (B24T) or Gruner actuator (G24T) with return spring, further equipped with a thermoelectric trigger sensor with activation at 72 °C. The actuator includes two limit switches for signaling the position of the damper blade. Power supply 24V AC/DC.
• BST0 or GST0
Activation mechanism with Belimo actuator (BST0, 24V AC/DC, power supply via 230V AC communication unit) or Gruner actuator (GST0, 24V AC/DC, power supply via 24V AC communication unit) with return spring, further equipped with thermoelectric trigger sensor with activation at 72 °C. The actuator includes two limit switches for signaling the position of the damper blade. Power and communication units Belimo BKN 230-24 or Gruner fs-UFC230-2.
• B24T-W or G24T-W
Activation mechanism with Belimo (B24T-W) or Gruner actuator (G24T-W) with return spring, further equipped with thermoelectric trigger sensor with activation at 72 °C and cables for power supply and communication unit (communication unit is not part of the mechanism). The actuator includes two limit switches for signaling the position of the damper blade. Power supply 24V AC/DC.
• B24T-SR or G24T-SR
Activation mechanism with Belimo (B24T-SR) or Gruner actuator (G24T-SR) with return spring and 0-10V control (possibility to set the position of the blade in any position), further equipped with a thermoelectric trigger sensor with activation at 72 °C. The actuator also includes limit switches for signaling of the damper blade position. Power supply 24V AC/DC. This activation mechanism can only be used for dampers with a height H ≥ 160 mm. This version cannot be used for the FDS-EI90S / EI120S dampers.
