OPERATION

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

®

: NFPA90A, NFPA92A, and NFPA92B for your 

application.

NOTE: The actuator is designed to operate for 30 min-

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

CHECKOUT

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 actu-

ator 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 actu-

ator is properly installed. See Installation section.

4. I

f 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 actu-

ator is properly installed. See Installation section.

4.

If the actuator is correctly installed but neither runs nor 

spring returns, replace the actuator.
