Quick Answer: Yes — but not always.
Fire and smoke damper actuators can sometimes be replaced separately from the damper assembly; however, replacement must consider certification, tested combinations, actuator compatibility, and Australian Standards requirements. Replacing an actuator without verifying compliance may affect fire system performance and certification.

The damper and actuator are not always supplied as a single integrated assembly; however, compliance generally depends on the tested and certified combination of damper, actuator, linkage arrangement, and installation method.”

Fire Damper vs Smoke Damper vs Combination Damper

Fire Damper

Purpose: stop fire spread
Usually fusible link operated
Installed at fire barriers / penetrations
Often passive device (no motor required)
Tested primarily for fire resistance performance

Smoke Damper

Purpose: control smoke movement
Integrated into smoke control sequence
Controlled from FIP/BMS/smoke system
Leakage performance important
Smoke dampers are commonly motorised to allow operation as part of a building smoke control sequence

Combination Fire/Smoke Damper

Does both jobs
Almost always motorised
Common in modern projects
Requires more care around actuator selection

Does The Motor / Actuator Need To Be Part Of The Damper?

The practical answer: “Browse our range of fire and smoke damper actuators”

YES — if:

Manufacturer certification says actuator is integral
Damper tested with a specific actuator
Fire test report references actuator model
You are replacing with an actuator not listed by manufacturer

NO — if:

The actuator is an approved substitute
Entire assembly still complies with test certification
Installed configuration matches tested arrangement
Manufacturer allows interchangeability

The critical point:
Compliance is generally for the damper assembly, not just the blade section. Swapping actuators because “the torque is similar” is often non-compliant.

Recent Actuator Clarification (Important)

There has been industry clarification around smoke damper actuator temperature ratings.

Recent guidance indicates that spring return actuators used only to achieve fail-safe positioning may not require the previously assumed elevated temperature rating requirements, provided control and wiring arrangements comply with AS1668.1 requirements. This has changed how many engineers interpret smoke damper actuator selection.

This matters because older specifications often over-called high-temp actuators.

Installation Rules People Commonly Miss

Access

Must be accessible for inspection/testing
Access panels required
Cannot bury above inaccessible ceilings

Penetration System

Damper installation must maintain FRL
Supports and clearances matter
Fire stopping around penetration matters as much as damper

Orientation

Install orientation must match tested configuration
Horizontal vs vertical may matter

Actuator Position

Many assemblies require actuator outside fire barrier
Thermal enclosures sometimes required
Linkage lengths may be restricted

Commissioning

Must function under fire mode sequence
Verify fail position
Verify end switches
Verify BMS / FIP integration

My Engineering Rule of Thumb

For replacements:

Fire damper only
→ replace as manufacturer specifies, avoid changing actuator arrangements.

Smoke damper
→ actuator substitution may be possible but verify certification.

Fire + smoke damper
→ treat damper + actuator + linkage + enclosure as one certified package.

If you are trying to substitute actuators because a model is obsolete (which happens constantly now), I would ask:

What is the damper manufacturer/model?
Original actuator model?
Fire damper / smoke damper / combination?
Is it part of a smoke exhaust system or just compartmentation?
Is there a test certificate available?

Without those, changing actuators becomes risky from an AFSS and certifier perspective.

Important Disclaimer

This article provides general technical guidance only and is not intended to replace project-specific engineering design, certification, manufacturer instructions, or regulatory requirements. Fire and smoke dampers must be selected, installed, tested, and maintained in accordance with applicable Australian Standards, manufacturer certification, and project fire engineering requirements. Always verify compliance requirements with the project certifier, fire engineer, mechanical engineer, and relevant authority having jurisdiction.

Key Compliance Reminder

Fire and smoke dampers are typically assessed as part of a tested assembly. Replacing dampers, actuators, linkages, or mounting arrangements without verifying certification and tested configurations may affect compliance and fire system performance.
