Honeywell ML8115A1005 Fast-Acting, Two-Position Actuators for Fire & Smoke Control

Description:

Honeywell ML8115A1005 is a Fast-Acting Two-Position Actuator ideally used for Fire and Smoke dampers (on/off control). This has an electrical rating of 24 Voltage and a counterclockwise spring return. The ML8115 Fast Acting Two-Position Spring Return Direct Coupled Actuator function is to accept an on/off signal from a single-pole, single-throw (SPST) controller.  This model includes an integral junction box for on/off damper control.  Reversible mounting allows the actuator to be used for either clockwise (CW) or counterclockwise (CCW) spring rotation. A clockwise or counterclockwise spring return option is available which is very reliable in smoke control systems requiring Underwriterís Laboratories Inc. UL555S ratings up to 350°F. Features:   Spring return timing of 15 seconds Internal Spring Stainless Steel Material A 95-degree angle rotation 30 lb-in. (3.4 N.m) minimum driving torque at 350°F (176°C). Integral spring return ensures the level of return torque. Housing Die-cast aluminum material No special cycling needed during long-term holding. Silent operation during holding. Patent-pending design eliminates the need for limit switches to reduce power consumption. The actuator holds rated torque at a reduced power level. Housing design allows flush mounting to the damper. Three conduit openings at the integral junction box
