ML4105, ML4115, ML8105, ML8115
Fast-Acting, Two-Position Actuators
FOR FIRE/SMOKE CONTROL APPLICATIONS

Động cơ điện cho van chống cháy, chống khói, van chặn lửa

Thiết bị điều khiển cho van chống cháy, chống khói, van chặn lửa

APPLICATION
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 Underwriterís Laboratories Inc. UL555S
ratings up to 350°F.
FEATURES
ï 30 lb-in. (3.4 Nïm) or 50 lb-in. (5.7 Nïm) minimum
driving torque at 350°F (176°C).
ï Integral spring return ensures level of return torque.
ï Fifteen-second spring return timing.
ï No special cycling required during long-term holding.
(See Operation section.)
ï No audible noise during holding.
ï Patent pending design eliminates need for limit
switches to reduce power consumption.
ï Models available for 24, 120, and 230 Vac.
ï Ninety-five degree angle of rotation.
ï Actuator holds rated torque at reduced power level.
ï Die-cast aluminum housing.
ï Housing design allows flush mounting to damper.
ï Integral junction box with three conduit openings
eliminates need for separate wiring box.
ï High-temperature indicator included.

SPECIFICATIONS
Models: See Table 1.
Dimensions: See Fig. 1.
Minimum Damper Shaft Length: 1-3/4 in. (45 mm).
Device Weight: 5 lb (2.3 kg).
Stroke: 95° ± 3°, mechanically limited.
Electrical Ratings: See Table 1.
Electrical Connections:
ML4105A,B, ML4115A,B, ML8105, ML8115: Two color coded
16 in. leads; includes ground screw.
ML4105C1008, ML4105D1007: Terminal block and ground
screw with option for connecting thermal switch.
ML4105C1016, ML4105D1015, ML4115C,D: 1m appliance
cable.
Three 7/8 in. holes for conduit connections (fittings not
included).
Mounting: 3/8 to 1/2 in. square or round damper shafts.
Actuator can be mounted with shaft in any position. Secure
hub to shaft with:
ML4105A,B, ML8105: Four 1/4-28 UNF set screws. Use
1/8 in. Allen wrench to tighten set screws.
ML4105C,D: Four 3 mm set screws. Use 3 mm Allen
wrench to tighten set screws.
ML4115, ML8115: Two 1/4-28 UNF set screws. Use 1/8 in.
Allen wrench to tighten set screws.
IMPORTANT
Honeywell does not recommend using linkages with
these actuators because side-loading of the output
hub reduces actuator life.
Temperature Ratings:
Ambient: 0°F to 130°F (-18°C to 55°C).
Shipping and Storage: -40°F to 140°F (-40°C to 60°C).
IMPORTANT
The actuator is designed to meet UL555S standards
at 350°F (176°C). The actuator must be tested with
the damper to achieve this rating.
Humidity Ratings: 5% to 95% RH noncondensing.

Noise Rating (Maximum):
Driving Open: 65 dBA at 1m.
Holding: 20 dBA at 1m (no audible noise).
