Fire and Smoke Damper Actuators for Sale

Find the Right Fire and Smoke Damper Actuator for Your System

Fire and smoke actuators are critical components in HVAC systems designed to prevent the spread of fire and smoke within a building. These specialized actuators control fire and smoke dampers, automatically closing them during a fire emergency to isolate affected areas and protect occupants.

Where Are Fire and Smoke Damper Actuators Used?

Fire and smoke damper actuators are found within the HVAC ductwork of various buildings, including commercial, industrial, institutional, and high-rise structures.

Building and fire safety codes strictly mandate the use of fire and smoke damper actuators in specific locations within a building's HVAC system. They are typically installed at strategic locations such as:

• Fire-Rated Walls: Where ducts pass through fire-rated walls, these actuators ensure automatic closure of dampers to maintain the integrity of the fire barrier.

• Between Building Zones: Actuators help create fire and smoke compartments, limiting the spread within a building.

• Stairwells and Shafts: Actuators protect these critical escape routes by preventing smoke infiltration.

Why Are They Important?

• Compartmentalization: Fire and smoke damper actuators are crucial for compartmentalizing a building during a fire. This slows the spread of fire and smoke, buying valuable time for evacuation and firefighting efforts.

• Protecting Lives: By limiting the movement of smoke and heat, these actuators help maintain safe escape routes and protect occupants.

• Minimizing Damage: Actuators can also help protect sensitive equipment or areas of a building from smoke damage.

Benefits of Quality Fire and Smoke Damper Actuators

• Life Safety: Reliable fire and smoke actuators are crucial for protecting lives and property.

• Code Compliance: Actuators often have UL555S or other certifications to meet strict fire safety codes.

• Ease of Installation: Well-designed actuators simplify installation and integration into fire safety systems.

• Durability: Actuators must withstand harsh conditions and potential exposure to heat and smoke.

Choosing the Right Fire and Smoke Damper Actuator

Selecting the right fire and smoke actuator involves several key factors to ensure reliable operation and compliance within your fire safety system. Let's break down some essential considerations:

Actuator Control Input

• Modulating: Provides precise damper positioning for airflow control and smoke management strategies beyond basic isolation.

• On/Off: Offers simple open/closed operation for primary fire and smoke containment.

Actuator Torque

Measured in inch-pounds (in-lb), represents the actuator's rotational force. Choose an actuator with sufficient torque to overcome airflow resistance and reliably operate the damper, even under adverse conditions.

• 18 in-lb: Typical for smaller dampers and applications with lower airflow resistance.

• 30 in-lb / 70 in-lb: Suitable for medium-sized dampers or those in areas with moderate airflow.

• 133 in-lb / 180 in-lb: Designed for larger dampers or applications where significant airflow resistance may be encountered.

Actuator Voltage

Ensure the actuator's voltage matches your building's electrical system for proper operation and safety.

• 24V: A common low-voltage option for control systems or where mandated by local codes.

• 120V / 230V: Standard line voltages found in most commercial and industrial buildings.
