Bulletin Issue Date May 20, 2004 Electric Smoke Damper Actuators The Modulating Electric Smoke Damper Actuators are oil immersed, spring return, linkage coupled actuator for modulating damper control designed to operate reliably in smoke control systems requiring Underwriters Laboratories Inc. (UL) 555S ratings up to 250 F. The actuator accepts a 0 to 10 V or 4 to 20 ma signal from a controller. The Low Torque Electric Smoke Damper Actuator is a spring return Direct Coupled Actuator (DCA) with an integral junction box for on/off signal from a Single Pole, Single Throw (SPST) controller. Models are designed to operate reliably in smoke control systems requiring Underwriters Laboratories Inc. UL555S ratings up to 350 F. The High Torque Electric Smoke Damper Actuators are spring return, Direct Coupled Actuator (DCA) for on/off damper control designed to operate reliably in smoke control systems requiring Underwriters Laboratories Inc. (UL) 555S ratings up to 350 F. The actuator accepts an on/off signal from a Single-Pole, Single-Throw (SPST) controller.
