DtiCorp.com Is Introducing The New Honeywell ML4115A1009 Actuator

Top Quote The ML4115, 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. End Quote
  • (1888PressRelease) February 07, 2012 - Fort Lauderdale, FL - Popular Honeywell online retailer DtiCorp.com (http://www.DtiCorp.com) is introducing the brand new Honeywell ML4115A1009 Fast-Acting, Two-Position Actuator - 30 lb-in, Spring Return CCW, 120 Vac +/-10%. 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 Underwriters Laboratories Inc. UL555S ratings up to 350F.

    Features:

    - 30 lb-in. (3.4 Nm) minimum driving torque at 350F (176C).

    - Integral spring return ensures level of return torque.

    - Stainless steel internal spring.

    - Fifteen-second spring return timing.

    - No special cycling required during long-term holding.

    - No audible noise during holding.

    - Patent pending design eliminates need for limit switches to reduce power consumption.

    - Models available for 24 and 120 Vac.

    - Ninety-five degree angle of rotation.

    - Actuator holds rated torque at reduced power level.

    - Die-cast aluminum housing.

    - Housing design allows flush mounting to damper.

    - Integral junction box with three conduit openings

    Specifications:

    - Minimum Damper Shaft Length: 1-3/4 in. (45 mm).

    - Device Weight: 5 lb (2.3 kg).

    - Stroke: 95 3, mechanically limited.

    - Honeywell does not recommend using linkages with these actuators because side-loading of the output hub reduces actuator life.

    - Temperature Ratings:

    - Ambient: 0F to 130F (-18C to 55C).

    - Shipping and Storage: -40F to 140F (-40C to 60C).

    - The actuator is designed to meet UL555S standards at 350F (176C). 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).

    - Cycling Requirements: Prolonged holding-period (1 year) testing of these actuators has been performed with no spring return failures. The actuator and the internal spring are designed to require no special cycling during long-term holding. 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. NFPA recommends periodic examination of each fire/smoke damper (semi-annually or annually) to ensure proper performance.

    - Design Life (at Rated Voltage): 60,000 full stroke cycles.
