NOTE: When using FSAF24-SR(-S) US actuators, only use accessories listed on this page.
Typical Specification
Proportional smoke, and combination fi re 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.
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.
Wiring Diagrams
1 Provide overload protection and disconnect as required.
2
CAUTION Equipment Damage!
Actuators may be connected in parallel.
Power consumption and input impedance must be observed.
3 Actuator may also be powered by 24 VDC.
4 No ground connection required. Double insulated.
5 Only connect common to neg. (–) leg of control circuits.
6
For end position indication, interlock control, fan startup, etc.,
FSAF24-SR-S US incorporates two built-in auxiliary switches:
2 x SPDT, 7A resistive, 2.5A inductive 120/250 VAC, UL Approved, one
switch is fi xed at 10°, one is adjustable 30° to 90°.
Meets UL requirements without the need of an electrical ground
connection.
The ZG-R01 500 Ω resistor converts the 4 to 20 mA control signal to
2 to 10 VDC.
WARNING Live Electrical Components! G
During installation, testing, servicing and troubleshooting of this product, it may be
necessary to work with live electrical components. Have a qualifi ed 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.
