Fire And Smoke Actuator

MS4209F; MS4309F; MS4709F; MS4809F; MS8209F; MS8309F

Spring return direct coupled actuators (DCA) for on/off damper control with an integral junction box. The actuator accepts an on/off signal from a single-pole, single-throw (SPST) controller. They are designed to operate reliably in smoke control systems requiring Underwriter's Laboratories Inc. UL555S ratings up to 350 F.
