Wiring Diagrams
FSAF24-SR (-S) US 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 Ωresistor, 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 failsafe operation. Actuator
shall open damper in <75 seconds per UL555S and shall spring closed in
under 20 seconds. Actuators shall be UL listed, 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.
Safety Note
Screw a conduit fitting into the actuator’s metal bushing. Jacket the
actuator’s input and output wiring with suitable flexible conduit. Properly
terminate the conduit in a suitable junction box.

Replacement Applications 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.

INSTALLATION NOTES
Actuators may also be powered by 24 VDC.
The ZG-R01 500 Ωresistor converts the 4 to 20 mA control
signal to 2 to 10 VDC.
Only connect common to neg. (—) leg of control circuits.
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 listed, one
switch is fixed at 10°, one is adjustable 30° to 90°.
APPLICATION NOTES
Meets UL requirements without the need of an electrical ground
connection. Actuator may also be powered by 24 VDC.
Double insulated.

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
components could result in death or serious injury.
