Transcription

1 Halton FDR Fire Damper for Rectangular and Circular Ducts Type-approved and compliant with the EN and EN standards. Design for installation in separating concrete and masonry walls and ceilings and lightweight plasterboard walls of fire compartments with fire resistance class EIS 30 to EIS 120. Readiness for installation with all wall options as delivered no additional frames needed. Manufactured in accordance with the ISO 9001 quality system. VTT, the Technical Research Centre of Finland, is responsible for external quality control. Installation in rectangular and circular ducts with diameter 630 to 1000 mm. Available with motorised or manual actuator. Double sealing, ensuring that the blades are tight when the fire damper is closed before and during a fire. Fire damper casing complying with the tightness requirements for Class C, EN Fire damper tightness meeting smoke damper requirement S of standard EN Suitability for use in ducts with a maximum pressure of 2800 Pa. Damper closing tests performed at 15 m/s duct velocity. Product models and Accessories Models equipped with either manual or electric actuators. 1

2 DIMENSIONS W/H: 200, 250, 300, 400, When the damper is installed on concrete and masonry walls or ceilings, the size of the installation hole is W/H mm. When the damper is installed on lightweight walls, the size of the installation hole is W/H mm. FDR Ø WxH D-1 La Lb C L L+2xC x x x Pressure drop and sound data Sound power level Lw, in in each octave band is computed bu adding the corresponding correction factor, Kok, to the sound pressure level in the selection chart according to the following equation. Lw = LpA + Kok The corresponding factor Kok is the average of the FDR operating area. 2

4 Material and finishing The FDR fire damper casing, installation flange, and installation frame are made of galvanised steel. The closing blade is made of calcium silicate and equipped with a flexible silicone seal as well as a graphite mass seal that expands at high temperatures.

The fire damper is equipped with either a motorised actuator or manual actuation arrangement. Both actuators have a visual position indicator. If the power in the motorised actuator system is switched off, the blade closes automatically. Europe and Russia models: In both actuator options, a fuse reacts to a rise in temperature, causing a spring-return blade to close. The motorised fire damper is delivered complete with a spring-return actuator and a fuse that is activated at 72 ºC. Sweden model: The electrical motor option is without thermal fuse and shall be connected to an automatic alarm system. The fire damper is made of fireproof materials. Once the fire damper has closed, the double sealing closes the duct tightly, effectively preventing the spreading of flue gases in the ventilation ductwork. The flexible seal of the double sealing system operates at lower temperatures, while the graphite mass seal expands to insulate the system at temperatures above 150 ºC. The FDR fire damper can be connected to the MSH control and testing system for fire dampers. The MSH unit enables the use of smoke detectors in the ductwork or rooms. The FDR fire damper can also be connected to other common building automation systems. Installation Installation on masonry walls When the fire damper is installed on concrete and masonry walls and ceilings between fire compartments, the blade shaft is always horizontal. An opening is always left in the separating element for the fire damper, and the product is subsequently grouted into this. To make installation easier, all products come with 4

5 an installation flange, which is used to fasten the fire damper to the concrete surface with screws before grouting. During installation, the fire damper and actuator must be protected with, e.g., a plastic cover. The correct operation of the fire damper must be ensured before and after grouting. When the damper is installed for concrete and masonry walls and ceilings, the size of the installation hole is W/H mm. Installation on lightweight plasterboard walls When the fire damper is installed on lightweight plasterboard walls between fire compartments, an opening for the fire damper must be left on the plasterboard in which the installation frame (included in the delivery) is first mounted. The blade shaft must always be horizontal. To make installation easier, the fire damper comes with an installation flange, which is used to fasten the fire damper to, e.g., the steel frame of the panel wall. The space between the fire damper and the installation frame is filled with a fire prevention mastic. During installation, the fire damper and actuator must be protected with. e.g., a plastic cover. The correct operation of the fire damper must be ensured after application of the fire prevention mastic. For lightweight walls, the size of the installation hole is W/H+110 mm; consult the section Documents / Installation Instructions for the size of the installation holes.

In motorised models, the fuse shall be activated at 72 C (E and R models). In the manually operated system, the fuse activation temperature corresponds to the specifications (50, 65, 72, 100 C). The fuse shall be located inside the damper, and it shall be possible to replace it from the outside. The fire damper shall have means for external opening / triggering of the release and closing. The fire damper shall include a position indicator. The fire damper shall be suitable for vertical and horizontal installation on concrete and masonry walls and on ceilings or lightweight plasterboard walls between fire compartments (EIS 30 to EIS 120). The technical properties of the type-approved fire damper shall conform to the EN and EN standards. The internal quality control of the fire damper manufacturer shall be based on the ISO 9001 quality system system, and the operations of the manufacturer shall be subject to external third-party quality control. Detailed installation instructions, as well as an installer s installation certificate form, are supplied with each product. See also the section Documents / Installation Instructions.
