Description The OpenAir direct coupled, fast-acting, two-position, spring return electronic actuators are available as 24 Vac, 120 Vac, and 230 Vac models. They are intended for use on UL-listed smoke control dampers and combination fire/smoke rated dampers. Features • Optional built-in auxiliary switches: Fixed switch points at 5° and 85° rotation. • Optional built-in Electronic Fusible Link (EFL) capability with four temperature ratings: 165°F (74°C), 212°F (100°C), 250°F (121°C), and 350°F (177°C). • Reversible fail-safe spring return. • High temperature polymer housing. • Pre-cabled, insulated lead wires. • Thirty-second powered operation at rated torque, temperature and voltage. • Fifteen-second mechanical fail-safe at rated torque and temperature. Application This actuator is used for the control of dampers requiring up to 80 lb-in (9 Nm) (GKD) and 200 lb-in (22 Nm) (GVD) driving torque. It is intended for control of UL-listed smoke control dampers and combination fire/smoke HVAC dampers. This actuator is designed to meet the 2002 revisions to the UL 555/555S and the AMCA Standard 520 specifications.

Operation When power is applied, the actuator coupling moves toward the open position, 90°. The actuator opens in 30 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 15 seconds nominal for 90°. The National Fire Protection Association NFPA 92A Standard for Recommended Practice for Smoke-Control System and UL 864 Standard for Control Units and Accessories for Fire Alarm Systems, require weekly self-tests for dedicated smoke control equipment used in a smoke control system. The National Fire Protection Association NFPA 72 Standard for National Fire Alarm Codes states that all life-safety systems are to be functionally checked at least annually. The GVD/GKD actuators do not require any periodic cycling to function properly as an integral part of an active smoke control damper system. Check the smoke control damper/actuator every time you functionally check your smoke detectors, emergency lights, and/or power generators for operation. Installation See OpenAir® GVD/GKD Series Electronic Damper Actuator Designed for UL Listed Fire/Smoke and Smoke Control Dampers Installation Instructions (A5W00094027) for detailed guidelines.
