Accessories ▲

The manual fire damper can be equipped with a bipolar limit switch (L2), which indicates the closing of the shutoff blade. The limit switch has potential-free points (no = normally open and nc = normally closed), which can be used to control other fire dampers equipped with an electric release, e.g., triggering an alarm in the fire suppression system. Electric actuator (BF) has integrated two limit switches. The maximum operating voltage and current is 400 V, 10 A.

Actuators

MA    Manual actuator, spring return

B1     BF24-T-2     operating voltage AC/DC 24 V (72 ºC) 18 Nm, with limitswitchs
B2     BF230-T-2   operating voltage AC 230 V (72 ºC) 18 Nm, with limitswitchs
 

Manual actuator

Manual actuator has to be opened by hand and closes the fire damper when fuse release the spring.
 

Electric actuator

A fusible link releases and cuts off operating voltage to the spring-return motor, allowing the spring to close the damper blades.

Function ▲

The Halton FDS is a rectangular fire damper, which prevents fire and smoke from spreading in ventilation ducts. Approved fire resistance classes are (EN 1366-2 and EN 13501-3):

• Ceilings: ES 60 
• Walls: ES 60, E 90 (both concrete/masonry and lightweight walls)

The fire damper is equipped with an electrical or manual actuator.
Under all options, a fuse responds to a rise in temperature, causing a spring-return blade to close.
Alternatively, the damper may be released by a system using an electric actuator.

Setting of the damper is performed from outside the device.

The fire damper is made of incombustible materials. Once the fire damper has closed, the blade(s) and sealing close the duct tightly, effectively preventing the spreading of flue gases.

Actuators have a visual position indicator.

The nominal release temperature of the fuse with an electric actuator is 72 °C.

The Halton FDS fire damper can be connected to the Halton Safe HSM control and testing system. The HSM system enables the use of smoke detectors in ductwork or in rooms. The Halton FDS fire damper also can be connected to common building automation systems.

Installation ▲

The damper may be installed both on concrete or masonry walls and ceilings and on lightweight walls. The blade direction in wall installation may be either horisontal or vertical.

The correct operation of the fire damper must be ensured before and after installation.

Set the fire damper by turning the shut-off blade to the open position.

The damper is to be cleaned after installation.

Detailed installation instructions, as well as an installer's installation certificate form, are supplied with each product. See also the section Documents for detailed installation guidance.
 

Installation in concrete and masonry walls

Installation opening: product size + 60 mm in both horisontal and vertical direction
1.  Concrete or masonry wall
2.  Rock wool, specific weight min. 40 kg/m3.
3.  Installation flange
4.  Anchor screw

Installation in lightweight wall

Installation opening: product size + 60 mm in both horisontal and vertical direction
1.  Installation frame; steel or wood
2.  Rock wool, specific weight min. 40 kg/m3.
3.  Plasterboard
4.  Installation flange
5.  Self drilling screw

An opening is always left in the separating element for the fire damper; the size of the installation opening is about W + 60 mm x H + 60 mm.

A supporting frame shall be installed around the opening of the lightweight wall.

All products come with an installation flange, which is used to fasten the fire damper with screws to the concrete surface or to the supporting frame within the lightweight wall (see installation drawings).

The gap between the damper and the separating element is filled with non wool after fixing of the damper.

Servicing ▲

In case the fuse of a manual fire damper is gone off, it can be reset after the fuse temperature has fallen below the release temperature. If the shutoff blade does not lock, the fuse is worn out and 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.

To ensure proper operation of the fire dampers, they should be inspected regularly. It is recommended that the fire damper be connected to automatic control and testing system Halton Safe HSM for (electric actuator 24-V).

Dampers not connected to an automatic testing system shall be tested periodically. The minimum recommended inspection period is twice a year or according to building code.

An inspection opening shall be installed in the proximity of the fire damper as indicated in the building code (not part of the product).

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.
