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.

• 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).

IMPORTANT

The actuator is designed to meet UL555S stan­dards at 350°F (176°C) on applicable marked
models. The actuator must be tested with the
damper to achieve this rating.

Settings (fixed): 7° nominal stroke, 85° nominal stroke

Design Life (at Rated Voltage):

30,000 full stroke cycles.

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.
