APPLICATION  
APPLICABLE LITERATURE  
The ML4105, ML4115, ML8105, and ML8115 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. Models are  
available with 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.

IMPORTANT  
All wiring must agree with applicable codes,  
ordinances and regulations.  
WARNING

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.

Location and Mounting  
The ML4105, ML4115, ML8105 and ML8115 DCA are  
designed to open a damper by driving the damper shaft in  
Preparation  
either clockwise  
or counterclockwise  
direction.  
Before mounting the actuator onto the damper shaft,  
determine the damper shaft size (3/8 in. to 1/2 in.  
[10 mm to 13 mm]).  
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.  
If damper shaft is 3/8 in. (10 mm) round or square, use part  
number 201391 Shaft Adapter (not supplied with actuator).  
Place adapter opposite set screws (see Fig. 3).  
CAUTION  
Tightly securing actuator to damper housing can  
damage actuator.  
NOTE: The damper shaft adapter centers a 3/8 in. (10 mm)  
damper shaft in the hub. Failure to use adapter can  
cause mounting screws to loosen. A 1/2 in. (13 mm)  
damper shaft does not require an adapter.  
Equipment Damage Hazard.  
Mount actuator to allow it to float along its vertical axis.  
NOTE: ML4105, ML4115, ML8105, and ML8115 Actuators  
are shipped in the fully closed position.

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 30 lb-in., maximum 60 lb-in. torque. Use  
1/8 in. or 3 mm Allen wrench (see Specifications for  
details) to tighten set screws.

OPERATION  
CHECKOUT  
The ML4105, ML4115, ML8105, and ML8115 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°.  
ML4105A,B and ML4115A,B (120 Vac model)  
1. Verify that the indicator has not turned black (see  
Temperature Indicator section).  
2. Check damper position.  
3. Connect 120 Vac to the black and white leadwires to  
drive the damper to the open position. The actuator  
should drive the damper.  
4. If the actuator does not run, remove power for at least  
two seconds.  
5. If the actuator spring returns, allow it to close entirely,  
then return to step 3.  
IMPORTANT  
A break in power of less than two seconds can cause  
the actuator to spring-return 5 degrees or less and  
remain in place until a break in power of longer  
duration.  
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.  
6. If the actuator does not spring return, verify that the  
actuator is properly installed. See Installation section.  
7. If the actuator is correctly installed but neither runs nor  
spring returns, replace the actuator.  
ML4105C,D and ML4115C,D (230 Vac model)  
1. Verify that the indicator has not turned black (see  
Temperature Indicator section).  
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.  
2. Check damper position.  
3. Connect 230 Vac to the blue and brown leadwires to  
drive the damper to the open position. The actuator  
should drive the damper.  
4. If the actuator does not run, remove power for at least  
two seconds.  
5. If the actuator spring returns, allow it to close entirely,  
then return to step 3.  
6. If the actuator does not spring return, verify that the  
actuator is properly installed. See Installation section.  
7. If the actuator is correctly installed but neither runs nor  
spring returns, replace the actuator.  
Temperature Indicator  
The temperature indicator, located on the cover of the  
actuator, provides evidence that the ambient temperature has  
exceeded 200°F (93°C). This is an indication that something  
in the building has caused temperatures to rise well above the  
long-term actuator operation temperature. While the actuator  
is capable of operating at 350°F (176°C) for extended periods  
of time, this indicator provides a visual signal that the actuator  
has been exposed to high temperatures for an undetermined  
period of time. The indicator provides a visual indication to fire  
authorities regarding the extent of damage after an event in  
the building.  
ML8105 and ML8115 (24 Vac model)  
1. Verify that the indicator has not turned black (see  
Temperature Indicator section).  
2. Check damper position.  
3. Connect 24 Vac to the red and black leadwires to drive  
the damper to the open position. The actuator should  
drive the damper.  
4. If the actuator does not run, remove power for at least  
IMPORTANT  
two seconds.  
If the indicator turns black, replace the actuator.  
5. If the actuator spring returns, allow it to close entirely,  
then return to step 3.  
NOTE: The actuator is designed to operate for 30 minutes  
during a one-time excursion to 350°F (176°C).  
6. If the actuator does not spring return, verify that the  
actuator is properly installed. See Installation section.  
7. If the actuator is correctly installed but neither runs nor  
spring returns, replace the actuator.
