Additional Installation Considerations
Installation of the DFD-150 requires careful attention to several key considerations to ensure that the damper functions effectively and complies with fire safety regulations.
Breakaway Connections and Security Features
Breakaway connections are an important feature for the DFD-150, allowing for a UL-approved method of attaching the duct to the damper sleeve. These connections are designed to disengage in the event of excessive force, preventing damage to the damper and ensuring that the fire suppression system remains functional.
Security bars, which are round steel bars welded into the damper sleeve, can be used to reduce security risks and reinforce the equipment. These bars help prevent tampering or unauthorized access to the damper, ensuring that it remains in its intended position and function.
Clean Wrap and Retaining Angles
A clean wrap is a thin film that adheres to the ends of the damper sleeve to prevent dust, dirt, and debris from entering the damper at the construction site. This feature is particularly important in environments where the damper is installed before the final stages of construction, as it helps maintain the integrity of the damper and reduces the need for post-installation cleaning.
Retaining angles or retaining plates are another critical component for the DFD-150. These can be ordered with the damper, pre-cut to the correct dimensions with holes at 1-inch increments to facilitate ease of installation. Retaining plates are especially important for true round fire dampers, as they allow for installation into a square opening.
