Siemens Building Technologies GGD Series Fire/Smoke Damper actuators are currently available. However, note that the actuator is rated as a package (UL 555S listed), which includes the damper, damper actuator, and a linkage kit for fire and smoke applications. They are intended for use on UL listed Smoke Dampers or combination Fire/Smoke Dampers. The damper manufacturer is the one who obtains the rating for this package.
