Fire and Smoke Damper Actuators

 

The Siemens GND, GGD Series fire/smoke damper actuators are spring return, 2-position, 15 second actuators designed to operate UL Listed smoke control dampers and combination fire/smoke dampers. The GND Series has 53 in-lb (6 Nm) of torque and the more powerful GGD Series has 142 in-lb (16 Nm) of torque. These actuators have patented built-in electronic fusible links; there is no need to buy/install separate parts to perform that function.
