The company’s new line of 30 lb-in. and 50 lb-in. spring-return direct-coupled actuators are designed to perform while meeting the UL555S Standard for smoke damper and fire-smoke damper applications. Features include two new spring-return actuator lines replace add-on external parts with integral components, an integral spring-return ensures constant torque, an integral junction box with three conduit openings takes the place of a separate wiring box, and the actuator’s design eliminates end switches.
