Fire And Smoke Actuator

ML4115; ML8115

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.

FEATURES

•Integral spring return.

•No audible noise during holding.

•Electronic circuitry provides efficient operation while eliminating the need for limit switches.

•Ninety-five degree angle of rotation for tight damper closure.

•Die-cast aluminum housing.

•Housing design allows flush mounting to damper.

•Integral junction box with three conduit openings eliminates need for separate wiring box.

•Mounts to 3/8 or 1/2 in. round or square shaft.

•High-temperature indicator included.
