Actionair DWFX-F Installation Guide

Vertical Damper Installation in a 

Plasterboard Wall

Actionair SmokeShield PTC - [AA/F13069], [AA/F10704]
Actionair FireShield - [AA/F10705]

Installation Method

1. Measure the overall Fire damper casing size w x h,  but 

for Smoke Shield  include the PTC Shroud (28mm) in 

the width but do not include any of the peripheral 

flange. 

2. Calculate the hole size...
3. 

For Fire Shield calculate the finished hole size by adding 

10-40mm to the case width and height.

4. 

For Smoke Shield calculate the finished hole size adding 

10-52mm to the width and 10-40mm to the height.

5. Calculate the hole to cut size by adding two board 

thicknesses to the finished hole width and height.

6. Mark out the hole on the partition and cut it out, cut-

ting the top and bottom edges first to maintain stabi

-

lity.

7. 

Frame out the hole with stud and track and cover this 

with board. Finish edges with joint filler.

8. 

Drill clearance holes in the damper flange at 150mm 

centres and such that they will allow screws to pull into 

the stud and track around the hole.

9. 

Install the damper and fasten.

10. 

Back fill with mineral/stone wool and pattress over 

this down to the spigot. Fasten with drywall screws at

Description:

If your proposed installation details differ from 

that shown here, please discuss this with the 

Building Control Authority (BCA), referencing 

this documentation, associated fire tests, 

assessments, and other documentation shown

below. Deviation from this drawing requires 

the approval of the relevant authority.

Installation Detail

Connecting ductwork omitted for clarity.  

Ductwork must be independently supported.  

There must be an appropriate break-away joint 

between the damper and connecting ductwork 

on both sides of assembly. Aluminium rivets or 

plastic cleats, clips, clamps and bolts etc. 

should be used for this, unless fire resisting 

ductwork is being used where fire resisting 

fixings should be used.  A minimum of 200mm 

between fire dampers installed in separate 

ducts and 75mm between fire damper and a 

construction element (wall/floor).

300mm centres such that they will allow screws to pull

11. Connecting ductwork omitted for clarity. Ductwork 

must be independently supported. There must be an 

appropriate break-away joint between the damper and 

connecting ductwork on both sides of assembly. Alu-

minium rivets or plastic cleats, clips, clamps and bolts 

etc. should be used for this, unless fire resisting duct

-

work is being used where fire resisting fixings should 

be used. A minimum of 200 mm between fire dam

-

pers installed in separate ducts and 75 mm between 

fire damper and a construction element (wall/floor).

12. Alternative partition systems to those shown within 

this installation manual can be used if they have been 

shown by test to have at least the same fire resistance 

when tested to BS EN 1364-1:1999 as is required of 

the damper. If the partition system has been success-

fully tested without stone mineral wool it does not 

have to be used in practice when only considering the 

fire performance of the complete system. The mineral 

wool may still be needed for other reasons e.g. acous-

tic performance.

actuator installation information on page 11.
