Application

N/A The type FSLF spring-return actuator is intended for the operation of smoke and combination fire and smoke dampers in ventiliation and air-conditioning systems. The actuator will meet requirements of UL555 and UL555S when tested as an assembly with the damper and will meet requirements of UBC for 15 second opening and closing at 350°F.
Square footage of damper operated will depend on make and model and the temperature required.
