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.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 sq.ft. minimum up to 4 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. The actuator is shipped in the zero fail-safe position to provide automatic compression against damper gaskets for tight shut-off. When power is applied, the manual mechanism is released and the actuator drives toward the open position where it stops rotating. The manual override can also be released physically by the use of a crank supplied with the actuator. SAFETY NOTE Screw a conduit fi tting into the actuator s bushing. Jacket the actuator s input and output wiring with suitable fl exible conduit. Properly terminate the conduit in a suitable junction box.

No Noise level (max) running 45 db (A) Servicing maintenance free Quality standard ISO 900, 5 year Belimo warranty Weight 6.0 lbs (.7 kg.) 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.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 to 0 VDC, or with the addition of a 500 Ω resistor, a 4 to 0 ma control input from an electronic controller or positioner. A to 0 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 FSAF4-SR. It is direct acting only. A reverse acting signal is required if it must spring open while V signal drives it closed. The torque is asymmetrical giving 80 in-lb drive and 33 in-lb spring. The FSAF resets after being driven or springing closed to the 0 position. There is a possible hysteresis of every 000 changes in signal. This can cause a position shift. It is recommended that power or signal be reset once a week. A manual override winder and locking mechanism is provided. If the manual winder is used when the actuator is powered, the actuator will release and drive closed to reset the 0 degree position. The actuator may not be mechanically parallelled or piggybacked. Each damper section should be controlled by a separate actuator. The wire 5 feedback can be used to parallel up to five additional actuators. If less than. 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. SAFETY NOTE Screw a conduit fi tting into the actuator s bushing. Jacket the actuator s input and output wiring with suitable fl exible conduit. Properly terminate the conduit in a suitable junction box.

Operation Mounting of the actuator to the damper axle shaft or jackshaft (3/8 to.05 ) is via a cold-weld clamp. Teeth in the clamp and V-bolt dig into the metal of both solid and hollow shafts maintaining a perfect connection. The specially designed clamp will not crush hollow shafts. The bottom end of the actuator is held by an anti-rotation strap or by a stud provided by the damper manufacturer. The actuator is mounted in its fail safe position with the damper blade(s) closed. Upon applying power, the actuator drives the damper to the open position. The internal spring is tensioned at the same time. If the power supply is interrupted, the spring moves the damper back to its fail-safe position. Subject to change. Belimo Aircontrols (USA), Inc.

17 FSTF0(-S) US On/Off, Spring Return, 0 VAC Torque min. 8 in-lb, for control of fire and smoke dampers Application The type FSTF spring-return actuator is intended for the operation of smoke and combination fire and smoke dampers in ventilation and air-conditioning systems. The actuator will meet requirements of UL555 and UL555S when tested as an assembly with the damper Square footage of damper operated will depend on make and model and the temperature required. Operation Mounting of the actuator to the damper axle shaft or jackshaft is via a cold-weld clamp. Teeth in the clamp and V-bolt dig into the metal of both solid and hollow shafts maintaining a perfect connection. The specially designed clamp will not crush hollow shafts. The bottom end of the actuator is held by an anti-rotation strap or by a stud provided by the damper manufacturer. The actuator is mounted in its fail safe position with the damper blade(s) typically closed. Upon applying power, the actuator drives the damper to the open position. The internal spring is tensioned at the same time. If the power supply is interrupted, the spring moves the damper back to its fail-safe position. M / - Subject to change.
