Halton FDR - Rectangular Fire Damper

ravenscroft halton fire damper fdrThe Halton FDR is a fire damper for rectangular or large circular ducts. It’s designed to prevent fire and smoke from spreading in ventilation ducts in case of a fire.

The advantages of Halton FDR fire damper:

  • Suitable for concrete/masonry walls and floors as well as plasterboard walls
  • External indication of damper position
  • Easy and fast to test from outside
  • Fuse easy to check and replace from the outside
  • No need for an inspection or access hatch
  • Manual operation or optional Belimo actuator
  • Can be used as a Smoke or combined Fire/Smoke damper when fitted with Belimo actuator

The FDR was designed with ease of installation and maintenance in mind. The fire damper comes complete with a telescopic installation frame. This makes installing a FDR considerably faster than most other fire dampers on the market. The external damper position indicator makes testing and servicing the damper easy and fast, and means that no inspection hatch is required.

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.ravenscroft halton fire damper fdr 2

The FDR is equipped with either a motorised spring-return actuator or manual spring-actuated arrangement. For ease of use both modes of actuation have a visual position indicator. If the power in the motorised actuator system is switched off, the blade closes automatically. With both actuation options, a fuse reacts to a rise in temperature, causing the spring-actuated blade to close. The motorised fire damper is delivered complete with a Belimo spring-return actuator and a fuse that is activated at 72 ºC.

The FDR fire damper can also be connected to other common building automation systems. These fire dampers can also be fitted with a Belimo BLF-T Spring-return actuator, combined with thermo-electric tripping device. This will turn the damper into a Smoke Damper.

Approval

Complies with the Australian & NZ Building codes as an acceptable solution (incorporating AS1682 as a guide line).

Verification as follows:
BRANZ Technical Opinion FAR4516-TO [2015] issued 18 January 2016.

The fire resistance in accordance with AS 1530.4-2005 of Halton FDR fire dampers up to a maximum size of 1,000 x 1,000mm would be at least 120 minutes for Integrity and Insulation.

Halton FDR fire dampers are suitable for installation in 110mm thick concrete walls, 150mm thick concrete floors, 116mm thick steel framed or timber framed plasterboard lined walls. They can also be installed in other types of construction such as lightweight concrete or hollow masonry blocks that have an equivalent fire resistance rating.

The FDR fire dampers have a Fire Resistance Level (FRL) -/120/120
