MS4104, MS4109, MS4604, MS4609, MS8104,

MS8109 Fast-Acting, Two-Position Actuators

FOR FIRE/SMOKE CONTROL APPLICATIONS

APPLICATION

The MS4104, MS4109, MS4604, MS4609, MS8104 and

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. (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.

(See Operation section.)

• 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°, 85° stroke).

MS4104, MS4109, MS4604, MS4609, MS8104, MS8109 FAST-ACTING, TWO-POSITION ACTUATORS SPECIFICATIONS Mounting: Round 1/2 inch shaft adapter with 1/4 inch set screws. Threads: ¼-20 UNC-2A Material: Alloy Steel hardened to HRC 45-53 Thread Lock: Nylon Patch Models: See Table 1. Table 1. Models. Voltage (Vac) Model IMPORTANT Honeywell does not recommend using linkages with these actuators because side-loading of the output hub reduces actuator life.

OPERATION CHECKOUT The MS4104, MS4109, MS4604, MS4609, MS8104 and MS8109 DCA are designed for use in Smoke Control Systems. If power fails, the actuator spring returns to the 0° position. The actuator mounts flush with the damper box. The actuator drives from 0° to 95° and spring returns back to 0°. MS4104F, MS4109F (120 Vac model) 1. 2. The actuators are operated by an spst two-position controller.
