Siemens Building Technology GVD126.1U Actuator
The Siemens Building Technology GVD126.1U is a high-torque 24V fire and smoke damper actuator engineered for precise two-position control in critical life safety HVAC systems. Delivering 200 lb-in torque, this rotary electronic actuator is specifically designed for integration with UL-listed smoke control dampers and combination fire/smoke dampers, ensuring compliance with UL555 and UL555S standards. Its robust construction features a NEMA 1 rated high-temperature polymer housing, capable of withstanding the rigorous demands of commercial ventilation environments.
For dependable fail-safe performance, the GVD126.1U actuator utilizes a mechanical spring return mechanism that automatically drives the damper to its safety position in under 15 seconds during a power loss. This unit includes two fixed auxiliary switches (set at 5° and 85°) for position feedback and features built-in Electronic Fusible Link (EFL) capability for thermal response. Its versatile design allows for direct-coupled mounting on shafts up to 1-inch, while the 3-foot plenum-rated cable simplifies field wiring for professional contractors.
Key Benefits:
- 200 lb-in torque provides sufficient power to operate large-scale fire and smoke dampers.
- Spring return fail-safe ensures immediate damper closure or opening during emergency power interruptions.
- Integrated auxiliary switches provide reliable remote status monitoring of damper position.
- Dedicated EFL capability supports seamless connection of electronic fusible links for localized heat detection.
- Compliant with UL555S smoke control standards for essential life safety system integration.
Common Questions:
Can the GVD126.1U be used with 24VDC power?
Yes, this actuator is compatible with both 24VAC and 24VDC supply voltages, making it adaptable to various building automation control circuits.
What is the typical run time for this actuator under load?
The motor drive run time for 90° of rotation is approximately 30 seconds, while the spring return fail-safe function operates in less than 15 seconds.
Does this unit support manual override for testing?
Yes, it features a manual override mechanism to allow technicians to position the damper during installation and system commissioning without power.
