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 ensures level of return torque.
• Fifteen-second spring return timing.
• No special cycling required during long-term holding.
• No audible noise during holding.
• Patent pending design eliminates need for limit switches to
reduce power consumption.
• Models available for 24, 120, and 230 Vac.
• Ninety-five degree angle of rotation for tight damper
closure.
• Actuator holds rated torque at reduced power level.
• Die-cast aluminum housing. Housing design allows flush
mounting to damper.
• Integral junction box with three conduit openings eliminates
need for separate wiring box.
• High-temperature indicator included.
