The actuator will meet requirements of UL555 and UL555S when tested as an assembly with the damper. Square footage of operating damper will depend on make and model per damper manufacturer UL testing. 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. Dimensions (Inches[mm]) Standard: 1/4" to 1/2" 1/4" to 5/16" 3.30" [83.72 ] 2.40" [61] 0.68" [16.7] 0.43" [11]0.77" [19.5] 4.5" [114] 0.2" [5.2] 6.28" [159.5] 3.0" [76.2] Safety Notes Screw a conduit fitting into the actuator’s bushing. Jacket the actuator’s input and output wiring with suitable flexible conduit. Properly terminate the conduit in a suitable junction box. Retrofit Safety Note Use of the FSTF for replacement of other makes of actuators is limited in damper area. The FSLF is preferred for direct coupled applications. The FSTF may be applied for linkage applications on dampers 1.5 sq.ft. and smaller at velocities under 2000 fpm.
