Fire and Smoke Damper Actuators

Honeywell fire and smoke damper actuators are designed to meet both UL-555 and UL-555S 350°F safety requirements for combined fire and smoke applications. The fast-acting actuators close dampers in 15-20 seconds, and the integral spring return ensures the consistent, proper level of torque.
