Note!
The Halton FDI fire damper’s CE approval is valid when the installation flange filled to the edges with fire prevention mastic on site. For futher information, see tab Documents / Installation.

The CE approval is also valid when the fire break grouting is made by Halton factory for Halton FDI fire damper installation flange (FB).

Electric actuator (N1, N2)

In the electric actuator system when a signal from building automation reaches the actuator or the fuse reacts to a rise in temperature (72 °C) power is switched off and the spring closes the blade of the damper. When the supply power is turned back on (e.g. during routine testing), the actuator opens the blade. In case of a power failure, the mechanical spring of the actuator ensures the failsafe function by closing the blade. The actuator is equipped with built-in limit switches for both open and closed position and have a visual position indicator.

The fuse can be replaced from outside the device.

The Halton FDI fire damper with 24V power supply is recommended to be connected to the Halton Safe Management 2.0 (SM2) fire and smoke safety control system. This system enables the use of smoke detectors in ductwork or room spaces. The Halton FDI fire damper can also be connected to other commonly used building automation systems.

Actuator options

N2         GNA326.1E/T12 (72 °C), 230 V, 7 Nm, with limit switch

Mechanical spring release, failsafe  (MA)

The fuse reacts to the rise of temperature (72 ºC) and the spring closes the blade. It needs to be opened manually.

This operating model has a visual position indicator and fuses can be replaced from outside the device.

Limit switch (LS1, LS2)

The limit switch (accessory) indicates the position of the damper blade. When it is open (safe position), the limit switch indicates this position. If the damper blade is closed (failsafe), the limit switch sends an impulse to the monitoring system. This system triggers an alarm and/or stops/starts fans, depending on the designed system. The limit switch has no influence on the thermal fuse or release mechanism.

The maximum operating voltage and current is 400 V, 10 A.

Function

The Halton FDI is a circular fire damper, which prevents fire and smoke from spreading in the ductwork of ventilation systems between fire compartments.

The Halton FDI is approved for vertical (ve) and horizontal (ho) installation in heavy and light-weight structures fulfilling the fire resistance class EI 60 (ve ho i <-> o) S  requirements. It is also approved for horizontal (ho) installation in concrete floors/ceilings to fulfill the fire resistance class E 90 (ho i <-> o) S requirements.

The fire damper is made of fireproof materials. Once the fire damper has closed, the double sealing closes the duct tightly, effectively preventing the spread of fire gases through the ventilation ductwork. The flexible silicone seal is tightening the blade at lower temperatures, while the graphite mass seal expands to insulate the system at temperatures above 150 ºC.

The fire damper is equipped with either electric (supply power 24V or 230V) or mechanical actuator (failsafe). All models are also equipped with a thermal fuse and a visual position indicator.

For further information, see section Operating models.

Installation

The Halton FDI fire damper is installed on concrete or masonry walls and ceilings and on lightweight walls.

See installation video from link below:
Halton FDI installation

An opening is always left in the separating element for the casing of the product to be led through the structure. The maximum diameter of the installation hole is the fire damper diameter D + 20 mm.

To make installation easier, all products come with an installation/casting frame, which is used to fasten the fire damper to the wall surface or the steel frame of the plasterboard wall.

The installation is finished by filling the casting frame from the front of the device with a gypsum-based firestop certificated fire break compound that is tested for use for this purpose (GBG from Palokatkomiehet Oy; CP 637 from Hilti; or FIREBREAK COMPOUND from Würth). During installation, the fire damper and actuator must be protected with, e.g. a plastic cover.

When the Halton FDI fire damper has a factory made pre fire break grouting (AC=FB), it can be installed to a lightweight panel walls by using four suitable screws to a steel frame or a wooden joist (see pictures below). The fire damper can be installed to the masonry structures by using four 8 mm steel wedge anchor.

 

The correct operation of the fire damper must be ensured both before and after grouting. Setting of the damper is performed from outside the device.

Detailed installation instructions, as well as an installer’s installation certificate form, are supplied with each product. See also the Documents / Installation Instructions.

The manual fire damper can be equipped with a bipolar limit switch (LS1, LS2) which indicates the closing of the shutoff blade. The limit switch has potential-free points, which can be used to control other fire dampers equipped with an electric release, e.g., triggering an alarm in the fire suppression system. The maximum operating voltage and current is 400 V, 10 A.

Servicing

If the blade of the manual fire damper does stay open, the fuse must be replaced. The fuse can be changed from outside the fire damper.

The fuse of a fire damper equipped with an electric actuator must be replaced if the fuse has been released because of a rise in temperature in the duct.

To ensure proper operation of fire dampers, they should be inspected regularly. The minimum recommended inspection period is every 6 months or according to the building code. It is recommended that the fire damper is connected to automatic fire damper management system Halton Safe Management 2.0 (SM2), operating voltage 24-VAC.

Upon failure during testing of the fire damper, maintenance service shall be ordered from an authorised Halton representative to ensure appropriate operation of the product.

Specification

The fire damper is CE marked according to the standard 15650:2010 and tested according to the test standard EN 1366-2.
A fire damper of fire resistance class EI 60 (ve,ho,i<->o) S and in concrete ceilings also E 90 (ho,i<->o) S, has a double-sealing solution that ensures fire-gas tightness and fire resistance both at room temperature and in high temperatures when the fire damper is closed.

In models with electrical actuator, the fuse shall be activated at 72 °C.
In the mechanical spring release model, the fuse activation temperature corresponds to the specifications (72 °C).
The fuse is located inside the damper, and it is possible to replace it from the outside.
The fire damper has means for external opening / triggering of the release and closing.
The fire damper includes a position indicator.

The fire damper casing complies with the tightness requirements for EN 1751 class C.

The fire damper is suitable for vertical and horizontal installation in concrete and masonry walls and on ceilings and lightweight plasterboard walls between fire compartments.
The blade shaft can be installed in either horisontal or vertical orientation, and the actuator can be installed in any direction.
The fire damper can be installed from the installation frame side without separate sealing of the installation opening on the wall.

The internal quality control of the fire damper manufacturer is based on the ISO 9001 quality system, and the operations of the manufacturer shall be subject to external third-party quality control.
