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 Building Technologies, 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.

Installation

Refer to the installation instructions for detailed guidelines.

CAUTION:

Read and carefully follow the Installation Instructions (129-255) to avoid

equipment damage.

Wiring

All wiring must conform to NEC and local codes and regulations.
