MS8109

The Honeywell MS8109 Fast-Acting, Two-Position Actuators are spring return direct coupled actuators (DCA) for Fire and Smoke dampers (on/off control).

MS8109F1010/U

Fast-acting, two-position actuator with 80 lb-in., spring return

MS8109F1210/U

Fast-acting, two-position actuator with 80 lb-in., 2 aux. switches, spring return

Overview

The Honeywell MS8109 Fast-Acting, Two-Position Actuators are spring return direct coupled actuators (DCA) for Fire and Smoke dampers (on/off control). The actuator accepts an on/off signal from a single-pole, single-throw (SPST) controller. Reversible mounting allows actuator to be used for either clockwise (cw) or counterclockwise (ccw) spring rotation.

Features

30 lb-in. (3.4 N•m) or 80 lb-in. (5.9 N•m) minimum driving torque at 350 F (176 C).
Reversible mounting facilitates use in either clockwise (cw) or counterclockwise (ccw) spring rotation.
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.
Actuator holds rated torque at reduced power level.
Die-cast aluminum housing.
Housing design allows flush mounting to damper.
Designed to operate reliably in smoke control systems requiring Underwriter’s Laboratories Inc. UL555S ratings up to 350 F.
Models available with SPST position-indicating switches (7 degree, 85 degree stroke).
