FSAF24(-S) US, FSAF120(-S) US  
On/Off, Spring Return, Meets 250°F [121°C] for Half Hour, 75 Seconds  
Torque min. 133 in-lb, for control of air dampers  
Application  
For two position control of UL555S rated dampers in HVAC. Actuator sizing should be  
done in accordance with the damper manufacturer’s specifications.  
The actuator is mounted directly to a damper shaft or jackshaft 3/8” to 1.05” in  
diameter by means of its universal clamp. A crank arm and mounting brackets are  
available if the actuator cannot be direct coupled to the jackshaft or damper shaft.  
Square footage of damper operated will depend on make and model of damper.  
Typically 12 sq.ft. minimum up to 24 sq.ft maximum will be operated for UL555S  
applications.  
Operation  
The FSAF series actuators provide true spring return operation for reliable fail-safe  
application and positive close-off on UL555S dampers. The spring return system  
provides constant torque to the damper with, and without, power applied to the  
actuator.  
The FSAF series provides 95° of rotation and is provided with a graduated position  
indicator showing 0 to 95°. The FSAF has a manual positioning mechanism which  
allows the setting of any damper position within its 95° of rotation.

WARNING Live Electrical Components!  
During installation, testing, servicing and troubleshooting of this product, it may be  
necessary to work with live electrical components. Have a qualified licensed electrician or other  
individual who has been properly trained in handling live electrical components perform these  
tasks. Failure to follow all electrical safety precautions when exposed to live electrical compo-  
nents could result in death or serious injury.

Typical Specification  
Large combination fire and smoke dampers are to be operated by Belimo FSAF  
series actuators. Manufacturer shall provide 5 year warranty.  
Actuators shall draw no more than 12VA at 230V or 10 VA at 24V.  
Where auxiliary switches are required for signaling, starting fans, or position indica-  
tion, -S model actuators, damper blade, or proximity switches shall be provided.  
Smaller dampers shall employ Belimo FSLF or FSNF actuators per damper manufac-  
turer recommendations.

FSAF24-SR(-S) US  
Proportional, Spring Return, 24 V, 2 to 10 VDC or 4 to 20 mA control signal  
Operation at 250°F for limited time per UL555S testing  
Torque min. 133 in-lb, for control of air dampers  
Application  
For proportional modulation of UL555S rated dampers in HVAC. Actuator sizing should  
be done in accordance with the damper manufacturer’s specifications.  
The actuator is mounted directly to a damper shaft or jackshaft up to 1.05” in diameter  
by means of its universal clamp. A crank arm and mounting brackets are available if  
the actuator cannot be direct coupled to the jackshaft or damper shaft.  
The actuator operates in response to a 2 to 10 VDC, or with the addition of a  
500 Ω resistor, a 4 to 20 mA control input from an electronic controller or positioner.  
A 2 to 10 VDC feedback signal is provided for position indication or master-slave  
applications. See Application Bulletin for details.  
Operation  
The FSAF series actuators provide spring return operation. There is no reversing  
switch on the FSAF24-SR. It is direct acting only. A reverse acting signal is required if  
it must spring open while 2V signal drives it closed. The torque is asymmetrical giving  
180 in-lb drive and 133 in-lb spring.  
The FSAF resets after being driven or springing closed to the 0 position. There is a  
possible hysteresis of 1° every 1000 changes in signal. This can cause a position shift.  
It is recommended that power or signal be reset once a week.

The wire 5 feedback can be used to parallel up to five additional actuators. If less than  
2.1 V or greater than 9.9V is given wire 3, actuator drives all the way to the respective  
end stop.  
The FSAF uses a DC motor which is controlled by a microchip The actuator may be  
stalled anywhere during its rotation without damage. If power is removed, the damper  
will spring closed. Interlocks must be provided as necessary for life safety functions  
and to shut down fan if required.

Typical Specification  
Proportional smoke, and combination fire and smoke dampers, shall be controlled by  
Belimo FSAF24-SR actuators. The control signal shall provide proportional damper  
control in response to a 2 to 10 VDC or, with the addition of a 500 Ω resistor, a 4 to  
20 mA control input from an electronic controller or positioner. The actuators must be  
designed so that they may be used for either clockwise or counter clockwise fail-safe  
operation. Actuator shall open damper in <75 seconds per UL555S and shall spring  
closed in under 20 seconds. Actuators shall be UL Approved, have a 5-year warranty,  
and be manufactured under ISO 9001 International Quality Control Standards.  
Actuators shall be as manufactured by Belimo. Actuators with auxiliary switches  
must be constructed to meet the requirement for double insulation so an electrical  
ground connection is not required to meet agency listings.  
Proportional control  
Replacement Application  
The number one “equal or better” requirement for use as a replacement for obsolete  
defective motors is the UL555S listing of the Belimo actuator with the damper for the  
application. The local authority having jurisdiction sets the requirements since UL  
has stated that they do not regulate replacements.

FSAF24-BAL(-S) US  
Spring Return, 24 V, 3-Position, 100% Open Override  
Operation at 250°F for limited time per UL555S testing  
Application  
For 3-position control of UL555S rated dampers in HVAC. Actuator sizing should be  
done in accordance with the damper manufacturer’s tests. In the absence of other  
information, use 10 in-lb of torque per square foot of area for opposed blade and 14  
in-lb for parallel blade fire and smoke dampers at 1000 fpm air velocity.  
The FSAF24-BAL is specifically designed to balance the air flow in ducts and  
simultaneously provide control of fire and smoke dampers. 0V = spring closed. 24V on  
wire 2, not 3 = drive to the potentiometer position (balanced flow). 24V on wire 3,  
regardless of the status of wire 2 = drive full open (smoke control extraction or  
pressurization). See Application Bulletin for details.

WARNING
Live Electrical Components!  
NOTE: When using FSAF24-BAL(-S) US actuators, only use accessories listed on this page.  
During installation, testing, servicing and troubleshooting of this product, it may be  
necessary to work with live electrical components. Have a qualified licensed electrician or other  
individual who has been properly trained in handling live electrical components perform these  
tasks. Failure to follow all electrical safety precautions when exposed to live electrical compo-  
nents could result in death or serious injury.  
Typical Specification  
Where indicated on drawings, combination fire and smoke and balancing dampers  
shall be controlled by Belimo FSAF24-BAL or equal actuators. The actuators must  
be designed so that they may be used for either clockwise or counter clockwise  
failsafe operation. Actuator shall open damper in <75 seconds per UL555S and shall  
spring closed in under 20 seconds. Actuators shall have a 5-year warranty and be  
manufactured under ISO9001 International Quality Control Standards.

The actuator shall spring closed if either the smoke detector or alarm system  
removes power from it. Actuator shall spring closed if the primary temperature  
thermodisc opens due to high ambient of >165°F or as otherwise indicted on  
drawings.

The actuator shall drive full open if either the smoke control system 100% open  
override or Fire Fighters Smoke Control Station override is activated. Damper shall  
spring closed again if the thermodisc of a combination fire and smoke damper opens  
due to high temperature (typically 250°F).
