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.
• 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).

INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
IMPORTANT
All wiring must agree with applicable codes,
ordinances and regulations.
Electrical Power Hazard.
Line voltage can cause death or serious injury
and short equipment circuitry.
Disconnect power supply before installation.
Electrical Shock or Equipment Damage Hazard.
Low voltage can shock individuals or short
equipment circuitry.
Disconnect power supply before installation.
Location and Mounting
The actuators are designed to open a damper by driving the
damper shaft in either clockwise or counterclockwise
direction. The actuator housing has two slots on the
bottom that, with a 205649 Mounting Bracket, secure it flush to
a damper box (see Fig. 2). When mounted correctly, these
slots allow the actuator to float without rotating relative to the
damper shaft.
Fig. 2. Mounting actuator to damper housing.
Preparation
Before mounting the actuator onto the damper shaft,
determine the:
— Damper/valve opening direction for correct spring
return rotation. The actuator can be mounted to provide
clockwise or counterclockwise spring return.
— Damper shaft size (see Specifications section).
Equipment Damage Hazard.
Tightly securing actuator to damper housing can
damage actuator.
Mount actuator to allow it to float along its vertical axis.

Installation
Device Malfunction Hazard.
Improper set screw tightening causes device
malfunction.
Ensure damper blade is in the correct position and
tighten set screws with proper torque to prevent
damper shaft slippage.
Actuator Damage Hazard.
Using actuator as shaft bearing causes device
damage.
Use actuator only to supply rotational torque. Avoid any
side loads to actuator output coupling bearings.
To install actuator, proceed as follows:
1. Place actuator over damper shaft; and hold mounting
bracket in place. See Fig. 2.
2. Mark screw holes on damper housing.
3. Remove actuator and mounting bracket.
4. Drill or center-punch holes for mounting screws (or use
no.10 self-tapping sheet metal screws).
5. Turn damper blades to desired normal (closed) position.
6. Place actuator and mounting bracket back into position
and secure bracket to damper box with sheet metal
screws.
7. Tighten set screws securely into damper shaft using minimum 100 lb-in., maximum 130 lb-in. torque. Use
1/4 in. wrench (see Specifications for details) to tighten
set screws.
IMPORTANT
1. All wiring must comply with local electrical codes,
ordinances and regulations.
2. Voltage and frequency of transformer must correspond with the characteristics of power supply and
actuator.
3. Use wires rated for at least 75°C (167°F).
4. The conduit fittings are designed for use with 3/8 in.
reduced-wall steel or aluminum flexible conduit.

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°.
The actuators are operated by an spst two-position controller.
When using an spst two-position controller, the actuator drives
to the damper fully open position when controller contact
makes and spring returns to the damper fully closed position
when controller contact breaks. The actuator drops to holding
power level on detection of stall, independent of hub position.
Cycling
The actuator and the internal spring are designed so that no
special cycling during long-term holding is required. 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
application.
NOTE: The actuator is designed to operate for 30 min-
: NFPA90A, NFPA92A, and NFPA92B for your
utes during a one-time excursion to 350°F (176°C).
MS4104F, MS4109F (120 Vac model)
1. Check damper position.
2. Connect 120 Vac to the black and white leadwires to
drive the damper to the open position. The actuator
should drive the damper.
3. If the actuator does not spring return, verify that the actuator is properly installed. See Installation section.
4. If the actuator is correctly installed but neither runs nor
spring returns, replace the actuator.
MS4604F, MS4609F (230 Vac model)
1. Check damper position.
2. Connect 230 Vac to the blue and brown leadwires to
drive the damper to the open position. The actuator
should drive the damper.
3. If the actuator does not spring return, verify that the actuator is properly installed. See Installation section.
4. If the actuator is correctly installed but neither runs nor
spring returns, replace the actuator.
MS8104F, MS8109F (24 Vac model)
1. Check damper position.
2. Connect 24 Vac to the red and black leadwires to drive
the damper to the open position. The actuator should
drive the damper.
3. If the actuator does not spring return, verify that the actuator is properly installed. See Installation section.
4. If the actuator is correctly installed but neither runs nor
spring returns, replace the actuator.
