ZoneFirst RDP-8 Damper

The ZoneFirst RDP-8 is a professional-grade 8-inch round zone damper designed for seamless integration into high-performance residential and light commercial HVAC zoning systems. Engineered with a heavy-duty 24-gauge galvanized steel shell, this single-blade damper provides reliable airflow control for duct systems rated up to 2.0” W.C. equipment. It features the advanced MP12M modular motor, a high-torque 12Vdc actuator that operates on a power open/power closed cycle in under five seconds. The plug-and-play design utilizes dual RJ11 modular ports, allowing contractors to daisy chain up to 10 dampers per zone using the included 25' PIW25 modular cord. A built-in two-color LED indicator provides immediate visual feedback: green for open and red for closed, facilitating rapid troubleshooting. With a life-cycle rating exceeding 1,000,000 cycles and an adjustable minimum position setscrew, the RDP-8 is the technician's choice for Plug-In-Play™ zoning reliability and streamlined installation.

• Efficient Installation: Modular RJ11 jacks and 4-conductor cabling eliminate traditional hardwiring, significantly reducing time on the job site.
• Precise Control: The MP12M motor provides direct drive linkage with an adjustable minimum position setting for customized airflow balancing.
• Visual Diagnostics: Integrated Open (Green) / Closed (Red) LED indicators allow for quick status verification without removing the motor cover.
• Versatile Mounting: Rigid construction allows for installation in any position within a properly sized 8" round duct.
• System Scalability: Dual-port design facilitates easy daisy chaining, supporting extensive zoning configurations from a single control panel port.

Can the RDP-8 be used with standard 24VAC control panels?
No, the RDP-8 is part of the Plug-In-Play™ series and is specifically designed for 12Vdc operation. It must be paired with compatible ZoneFirst 12Vdc modular control panels.

What happens if the internal motor fails?
The MP12M actuator is designed for simplified field replacement. By loosening a single setscrew, the motor can be swapped in under a minute without disassembling the ductwork or damper blade assembly.

Is the modular cable included with the unit?
Yes, each ZoneFirst RDP-8 ships with a 25-foot PIW25 modular cord to ensure immediate connectivity between the damper and the zone controller or the next damper in the chain.
