MS4609F1210 Honeywell | 230V Fire/Smoke Actuator with 95° Stroke

Product Description

The Honeywell MS4609F1210 is a high-performance, fast-acting fire/smoke damper actuator designed for use in HVAC systems within commercial and industrial buildings. Part of Honeywell’s MS Series, this actuator ensures reliable and rapid damper closure in emergency situations, enhancing building safety by helping to control the spread of smoke and fire.

Featuring a spring return mechanism, the MS4609F1210 automatically drives the damper to a safe position when power is lost, providing peace of mind in critical environments. It is ideal for applications requiring UL-listed fire and smoke dampers. The actuator operates with two-position control and includes two SPST auxiliary switches to offer status feedback or enable interlocking with other systems.
