INSTALLATION

When Installing this Product...

1. Read these instructions carefully. Failure to follow

them could damage the product or cause a hazard-

ous 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.

WARNING

Electrical Power Hazard.

Line voltage can cause death or serious injury

and short equipment circuitry.

Disconnect power supply before installation.

ENSURE THAT MOUNTING ASSEMBLY PREVENTS ACTUATOR

ROTATION AND ALLOWS ACTUATOR TO FLOAT ALONG INDICATED

AXIS. WHEN TOO TIGHT, THE RESULTING BINDING CAN DAMAGE

THE ACTUATOR OR REDUCE TORQUE OUTPUT.

CAUTION

Electrical Shock or Equipment Damage Hazard.

Low voltage can shock individuals or short

equipment circuitry.

Bracket, secure it flush to a damper box (see Fig. 2). When

mounted correctly, these slots allow the actuator to float

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. 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 sec-

tion.

4. If the actuator is correctly installed but neither runs

nor spring returns, replace the actuator.

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.

MS4604F, MS4609F (230 Vac

model)

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

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 sec-

tion.

4. If the actuator is correctly installed but neither runs

nor spring returns, replace the actuator.

Association (NFPA) National Fire Codes : NFPA90A,

NFPA92A, and NFPA92B for your application.

NOTE: The actuator is designed to operate for 30 minutes

during a one-time excursion to 350°F (176°C).

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 sec-

tion.

4. If the actuator is correctly installed but neither runs

nor spring returns, replace the actuator.
