MS4609, MS8104, MS8109 Fast-Acting, Two-Position Actuators

FOR FIRE/SMOKE CONTROL APPLICATIONS

SPECIFICATION DATA

APPLICATION

The MS4104, MS4109, MS4604, MS4609, MS8104, MS8109 Fast-Acting, Two-Position Actuators are spring return direct coupled actuators (DCA) with an integral junction box for on/off damper 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 return and are designed to operate reliably in smoke control systems requiring Underwriter’s Laboratories Inc. UL555S ratings up to 350°F if applicable.

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.

•Stainless steel internal spring.

•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 operated reliably in smoke control systems requiring Underwriter's Laboratories Inc. UL555S rating up to 350°F.

•Non-UL marked version available.

•Models available with SPST position-indicating switches (7°, 85° stroke).

Cycling Requirements:

The actuator and the internal spring are designed to require no special cycling during long-term holding.

Honeywell recommends following all local, state and national codes for periodic testing of the entire smoke control system. Refer to National Fire Protection Association (NFPA) National Fire Codes®: NFPA90A, NFPA92A and NFPA92B for your application.

NFPA recommends periodic examination of each fire/smoke damper (semi-annually or annually) to ensure proper performance.

Minimum Damper Shaft Length:

2 in. (51 mm).

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

IMPORTANT

Honeywell does not recommend using linkages with these actuators because side-loading of the output hub reduces actuator life.
