Critical Spring-Return Function
In the event of a power failure or fire alarm signal, the actuator automatically returns the damper to its safe, pre-set position (either open or closed) in under 75 seconds, ensuring compliance with smoke control protocols.
Dual Voltage Flexibility
Engineered for global applications. Choose from low-voltage AC/DC 24V models for BMS integration or direct AC 100-240V options for simpler installations, reducing the need for additional transformers.
Integrated Thermal Sensor Option (DST Type)
Select models include a built-in SAF72 thermal sensor. This provides an added layer of safety by triggering the actuator's return function automatically upon detecting high ambient heat, independent of the main fire alarm panel.


Robust Protection For Harsh Environments
With an IP54 rating, the actuator is protected against dust and water splashing, making it suitable for installation in plenums, mechanical rooms, and other demanding environments. It operates reliably in temperatures from -20°C to +50°C.
Manual Override
A manual override feature allows technicians to easily position the damper manually for testing, maintenance, or during system commissioning without the need for tools.
Clear Mechanical Position Indicator
Quickly and reliably see the damper's position (open/closed) at a glance, ensuring system status is always visib
Applications of Fire Smoke Actuators
Stairwells & Elevator Shafts
Pressurize these escape routes to keep smoke out, ensuring safe evacuation.
Ductwork
In ducts passing through smoke barriers, they close to prevent smoke transfer between floors or areas.
Atria & Large Spaces
Control airflow and smoke movement in vast open areas.
Lobbies & Corridors
Manage air pressure and smoke spread in these critical circulation zones.
Smoke detector placement: When smoke dampers are a part of the installation, detectors should always be installed into the duct.
Heat responsive components: These bi-metals are what make a damper afire damper and, consequently, a crucial element of the combination fire and smoke damper.
Support structures: In certain applications, boards may be used to prop up the damper and keep it in place.
