Health and safety

• This process must be undertaken by competent per-

sons. More than one person may be required to ensure

the safe handling of large dampers and other materi-

als. Use must be made of access equipment to ensure

unsafe practices are not used to approach walls or dif-

cult access areas.

• Standard site PPE should be used (minimum steel toe

cap boots, hard hat); together with any protective

eyewear, gloves and masks, when drilling or cutting is

being undertaken. The latter should also be used when

handing the wall construction materials, as dened by

the material suppliers. If loud equipment is being used,

hearing protection should be used.

• All waste materials should be collected and disposed of

as dened by the relevant supplier.

• Actuators: All wiring should be carried out in accor-

dance with the wiring details provided by the IEE and

BS regulations and by a competent person. Care must

be taken when installing and inspecting dampers, as

they are likely to close without warning due to loss of

electrical power or a temperature rise in the ductwork.

This is their prime function. Do not insert any items,

ngers or limbs between the blades. Larger dampers

must be handled in accordance with current regula-

tions and good practice due to weight.

Why Swegon actionair DWFX-F control mode does not operate electrically?
- V
  Victoria ShortAug 26, 2025
  If the control mode does not operate electrically, here are a few possible reasons: * The ETR (Electrical Thermal Release) may not be correctly fitted to the duct. Screw fix to the duct, ensuring both parts of the ETR are fully together, but avoid over-tightening. * The mode might be incorrectly wired. Check the wiring according to the correct procedures. * The ETR cables could be damaged or tampered with. If this is the case, replace the mode with a new one.

What to do if Swegon actionair DWFX-F Fire and Smoke Dampers control mode operates but there is limited or no blade movement?
- B
  barronjoannaNov 8, 2025
  If the control mode operates, but the damper blades have limited or no movement, consider these potential causes and solutions: * The mode may not be correctly synchronized with the interface. Remove the motor from the interface, ensure the motor is in a fully released state, set the position of the interface, and refit the motor with the label uppermost, including the motor location pointer and washer. * The damper could be damaged or poorly installed, requiring a new damper or re-installation. * The interface might not be fitted correctly to the damper. Ensure it is fitted correctly, making sure the retaining pin protrudes through the location hole in the shroud. * Foreign matter may be impeding blade movement. Check for and remove any obstructions. * The motor location point...

Inspection and handover check sheet

The Actionair DWFX-F is a range of fire and smoke dampers designed for installation in plasterboard and masonry walls, including applications under concrete slabs. These dampers are crucial components in maintaining fire compartments within buildings, preventing the spread of fire and smoke through ductwork. The product line includes both SmokeShield PTC (Positive Temperature Coefficient) and FireShield variants, each with specific installation methods and performance characteristics.

Function Description:

The primary function of the DWFX-F dampers is to automatically close upon detecting a rise in temperature or loss of electrical power, thereby sealing off ductwork penetrations in fire-rated walls. This action helps to compartmentalize fire and smoke, protecting escape routes and limiting damage.

SmokeShield PTC Dampers: These are actuated, failsafe-close dampers with low smoke leakage, often referred to as Fire/Smoke dampers. They are designed to be used with fire-separating elements to maintain fire compartments. Their operation is triggered by a thermal actuator, which expands at a specified temperature (typically 72°C), causing the damper blades to release and close.
FireShield Dampers: These are fire dampers tested to BS EN 1366-2 and classified under BS EN 13501-3. They also operate on a failsafe-close principle, typically triggered by a thermal release mechanism.

Both types of dampers are designed to operate without warning in the event of electrical power loss or a temperature rise in the ductwork, fulfilling their critical safety function.

Important Technical Specifications:

Materials: The thermal actuator in SmokeShield PTC dampers utilizes a helical memory metal compression spring made from a special Cu-Zn-Al brass alloy.
Thermal Release Temperature: Standard cassettes are available for 72°C. Alternative thermal link temperatures or electrical release options (230V AC or 24V AC/DC electromagnets) are available.
Electrical Specifications (Mode 5 PTC 24V):
- Supply: AC/DC 24V, 50/60 Hz
- Power Consumption: 12.5 VA / 10/2 W (motoring/reset)
- Inrush Current (Imax): 8.3A @ 5ms
- Close Time: ≈ 22 seconds
- Open Time: ≈ 60 seconds
- IP Rating: IP54
Electrical Specifications (Mode 6 PTC 230V):
- Supply: AC/DC 230V, 50/60 Hz
- Power Consumption: 14 VA / 12/4 W (motoring/reset)
- Inrush Current (Imax): 8.3A @ 5ms
- Close Time: ≈ 22 seconds
- Open Time: ≈ 60 seconds
- IP Rating: IP54
Electrical Specifications (Mode 5-3P):
- Supply: AC/DC 24V, 50/60 Hz
- Power Consumption: 9.5 VA / 7/2.5 W (motoring/holding)
- Inrush Current (Imax): 8.3A @ 5ms
- Spring Close Time: ≈ 18 seconds
- Motor Open Time: ≈ 120 seconds
- Control Signal: Standard 0-10V DC
- IP Rating: IP54
Installation Clearances: A minimum of 200 mm between fire dampers installed in separate ducts and 75 mm between a fire damper and a construction element (wall/floor) is required, unless otherwise tested. Ductwork must be independently supported, with an appropriate break-away joint between the damper and connecting ductwork on both sides.
Damper Blades: Can be installed in a vertical orientation with the actuator mounted at either the top or bottom.

Usage Features:

Self-Latching Removable Release Mechanism Cassette: This feature allows for easy replacement of the cassette without tools by manually releasing a retaining clip. This simplifies maintenance and ensures quick resetting.
Manual Operation: Simple hand operation enables the damper curtain to be reset and latched in the fully open position. This is particularly useful for periodic functional testing in accordance with British Standard BS9999:2008 Code of Practice for fire safety.
Remote Release Operation: FireShield dampers can be closed remotely via a Bowden cable (manual action) or an electrical electromagnet (230V AC or 24V AC/DC fail-safe action), independent of the thermal actuator.
Reset Operation: Single-hand operation allows each blade to push the latch back under spring tension, securing the damper once fully reset.
Actuator Orientation: The control mode (actuator) can be fitted in three orientations (vertically down, horizontally, and vertically up) to accommodate various installation requirements and height restrictions.
ETR (Electrical Thermal Release) Installation: The ETR should ideally be mounted in the top half of the duct and/or above the level of the interface. A self-adhesive template is provided for drilling necessary holes. Proper fitting of the ETR is critical for unit operation and safety. The ETR cable must not be cut or lengthened, as this will void warranties due to a built-in safety feature.

Maintenance Features:

Periodic Maintenance: Actionair recommends a regular service and inspection program to ensure correct operation. This includes:
- 6-Monthly Checks: Actuator wiring, limit switch wiring, damper cleanliness (clean and lubricate if necessary), condition of blades and seals, blade obstructions, and damper release mechanism (through activation or ETR/Thermal Fuse release). Also, ensure the damper is in its normal operational position after inspection.
- Monthly Checks: Complete actuation of the damper from the control panel (if installed) and check for faults.
Competent Persons: All maintenance and installation must be undertaken by competent persons, with specific expertise required for functional safety assessment of smoke and fire damper products.
Access Requirements: Adequate means of access must be provided for inspection, testing, and maintenance of both the fire damper and its actuating mechanism, as per Clause 10.12 of Approved Document B, Volume 2.
Troubleshooting Guide: The manual provides a quick guide to common problems, such as the interface assembly not fitting, control mode not operating electrically, or limited/no blade movement, along with recommended actions.
Handover Check Sheet: A comprehensive check sheet is provided for installers to complete upon installation, verifying correct damper type, location, identification, supports, orientation, access, cleanliness, and functionality. This ensures compliance and proper handover to the client.
