Operation
When power is applied, the actuator coupling moves toward the open position, “90°”.
The actuator opens in fifteen seconds nominal, 90° at 60 Hz. In the event of a power
failure or when operating voltage is turned off, the actuator returns to the “0” position.
The return time is fifteen seconds maximum for 90°.
The GGD actuator does not require any periodic cycling to function properly as an
integral part of an active smoke control damper system.
NOTE: Siemens Industry, Inc. however, strongly suggests that all life safety
systems are functionally checked periodically. Check the smoke control
damper/actuator every time you functionally check your smoke detectors,
emergency lights, and/or power generators for operation.
