Middle Atlantic MPR Series Modular Power Raceway System - Standalone Sequencing Controller

The Middle Atlantic MPR Series delivers professional-grade power management through a seamlessly integrated Modular Power Raceway System paired with a dedicated sequencing controller. This setup brings six-step sequencing to life, coordinating startup for AV gear, displays, projectors, and equipment racks with precision. Whether you’re outfitting a broadcast studio, corporate meeting space, or home theater, the standalone sequencing controller option ensures safe, orderly power-up and a cleaner, more reliable power distribution workflow. Built for flexibility, the MPR family combines the USC-6R rackmount sequencer with raceway-mounted or standalone sequencing modules to suit your installation needs.

• Six-step sequencing with USC-6R: The rackmount USC-6R sequencer provides a precise six-step power-up and power-down sequence, helping protect sensitive devices from inrush currents and voltage fluctuations during startup.
• Flexible mounting options: Choose raceway-mount MPR-SEQ for integrated rack-and-raceway installations, or opt for the standalone MPR-SEQ-1C controller for independent sequencing without a full rack setup. The versatility makes it easy to tailor the system to your space and workflow.
• Low-voltage trigger control: Sequencing is driven by simple low-voltage switch closures, enabling easy integration with building automation, wall panels, or custom control systems that trigger AV power sequencing without high-voltage wiring complexity.
• Local and remote initiation: Initiate sequencing locally using a front-panel switch or connect remote triggers to synchronize power sequencing across multiple devices or rooms, providing consistent startup across your installation.
• Modular, scalable power management: The MPR system is designed to grow with your needs, offering a clean, modular approach to power distribution in AV environments while delivering reliable sequencing, surge protection concepts, and organized cable management within the raceway framework.

How to install Middle Atlantic MPR Series Modular Power Raceway System - Standalone Sequencing Controller

Before beginning, confirm your space and identify where the USC-6R rackmount unit, MPR-SEQ raceway module, or the standalone MPR-SEQ-1C will reside. Plan the wiring path so that low-voltage control lines reach your trigger sources without interfering with primary power cables. The MPR system is designed to integrate cleanly with existing Middle Atlantic power raceways, providing a cohesive aesthetic and practical cable management solution for professional AV installs.

First, mount the sequencing components in their preferred locations. If you’re using the rackmount USC-6R, install it securely in a standard equipment rack with adequate ventilation. For raceway-mounted configurations, attach the MPR-SEQ module within the raceway section you’ve allocated, ensuring stable alignment and unobstructed access for front-panel controls and any indicator LEDs. If you’re deploying a standalone MPR-SEQ-1C, place it in a suitable location where control wiring can reach the trigger sources and where the unit remains easily accessible for maintenance and testing.

Next, establish your low-voltage control wiring. Connect the trigger devices (such as wall switches, automation controllers, or dimmer panels with low-voltage outputs) to the sequencing input per the installation guidelines. Keep conductors neatly routed within the raceway or along approved cable pathways, and label lines to simplify future troubleshooting. It’s important to verify that the control signals are compatible with the USC-6R or MPR-SEQ inputs and that they are configured to initiate the six-step sequence when desired.

Then, connect the MPR system to the power distribution arrangement. Route AC power feeds through the raceway and into the downstream devices that will be sequenced. Ensure that all devices intended to participate in the sequencing are connected to the appropriate stage outputs or power taps endorsed by the MPR configuration. Check for secure plug connections, secure cable management, and clear labeling to prevent accidental mis-wiring during maintenance or expansion.

Power up the system and perform a baseline test. Use the local front-panel control to initiate the six-step sequence and observe the orderly ramp-up of connected equipment. If remote triggers are configured, test those paths by triggering from your automation system or wall control to confirm that all devices synchronize as intended. Monitor indicators on the USC-6R and MPR modules to verify proper sequencing and promptly address any fault indicators or misfires.

Finally, document the configuration. Record the wiring diagrams, trigger source assignments, and the exact order of devices in the sequence to simplify future upgrades or service visits. Use the modular MPR platform to scale your installation as new components are added, maintaining a consistent startup profile and a clean power-management footprint within your rack or raceway.

Frequently Asked Questions
