Electric actuator (B1, B2, B3, B4)

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 automatically. When the supply power is turned back on (e.g. during testing), the blade opens automatically. The actuator is equipped with built-in limitswitches for both open and closed position.

The Halton FDC fire damper with 24V power supply is recommended to be connected to the Halton Safe fire damper management system (HSM). This system enables the use of smoke detectors in ductwork or room spaces. The Halton FDC fire damper can also be connected to other commonly used building automation systems

Manual actuator (MA)

The fuse reacts to the rise of temperature (72 ºC as default) and the spring closes the blade automatically. It needs to be opened manually.
Optional fuse release temperatures 50 and 100 °C are also available for the manual actuator.

Limitswitch (MS)

The limit switch indicates damper blade position, sending an impulse to other remote-release fire dampers if the blade is closed, tripping an alarm in the monitoring system and/or stops / starts fans, depending on the designed system. The limit switch has no influence on the thermal fuse or release mechanism.

Function

The Halton FDC is a circular fire damper of fire resistance class EIS 120, which prevents fire and smoke from spreading in ventilation ducts. 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.

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.

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 Halton FDC fire damper can be connected to the Halton Safe fire damper management system (HSM)  and testing system for fire dampers. The HSM unit enables the use of smoke detectors in the ductwork or rooms. The Halton FDC fire damper also can be connected to other common building automation systems.

Installation

Installation on concrete and 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 subsequently is grouted into this.
To make installation easier, all products come with 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 on concrete and masonry walls or ceilings, the size of the installation hole is D + 50 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 in 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 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 varies with the specific product; consult the section Documents / Installation Instructions for the size of the installation holes.

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