    RETROFIT SEQUENCER

    Add intelligent sequencing to existing panels, simplified.

    The MRTS Retrofit Sequencing Panel provides a straightforward solution for adding robust, one-touch sequential control to any installation using a Square D cabinet that accepts QO circuit breakers. Instead of a costly panel replacement, the MRTS mounts next to the existing cabinet and integrates with new Square D remote-controlled breakers. This approach significantly reduces installation complexity and cost, making it ideal for upgrading legacy sound systems and AVL infrastructure.

    Each MRTS unit is housed in a lockable, rain-tight Hoffman cabinet and features our proven MS-12 Modular Sequencer boards. The system is engineered for long-term reliability and energy efficiency, requiring no holding current to maintain its state.

    SYSTEM COMPATIBILITY

    Integrate the MRTS into your facility.

    The MRTS is designed to work with specific panels and control accessories.

    Square D QO Load Centers

    Designed exclusively for use with any existing Square D electrical cabinet that accepts QO-series breakers.

    Square D QO Motorized Breakers

    Provides control signals to operate Square D QO remote controlled breakers, which must be purchased separately.

    Contact Closure Switches

    Integrates with any dry contact closure switch, such as the LynTec SS-2 series, for simple one-touch control.
    CONFIGURATION OPTIONS

    Configure your retrofit.

    Select the right MRTS model and options for your existing electrical panel.
    Available Models

    Choose the model based on the number of circuits you need to sequence:

    • MRTS-12: Provides control for up to 12 motorized circuit breakers in a single Square D QO panel.
    • MRTS-24: Expands capacity with a second control board to sequence up to 24 motorized circuit breakers.
    Breaker Integration

    The MRTS panel works exclusively with Square D remote controlled breakers, which must be ordered separately:

    • Required Breakers: Order as many Square D QO remote controlled breakers as you need to sequence for your project.
    • Installation: The new breakers plug into the existing Square D panel and are then wired to the MRTS control boards.
    Control Options

    Control is handled via simple and reliable contact closures:

    • Inputs (Standard): A contact closure input is standard on all panels for one-touch system control via a key switch or remote button.
    • Outputs (Optional): Contact closure outputs can be added to any panel to signal system status to other equipment.

    FAQ

    FAQs about the MRTS Panel

    Can I use this with a panel that is not a Square D QO type?

    No, the MRTS is specifically designed and engineered to provide sequencing for Square D cabinets that accept QO-series circuit breakers. It is not compatible with other manufacturers’ panels or breaker types.

    Does this require a LynTec technician for setup?

    No, the MRTS is designed for simple setup and does not require on-site commissioning by a LynTec specialist. The system is pre-configured for straightforward installation by a qualified electrician.

    How is the sequencing controlled?

    The system is controlled via a simple contact closure input, which is a standard feature. This allows you to use a key switch, a remote button like our SS-2, or any other dry contact switch for one-touch operation.

    What else do I need to order besides the MRTS panel?

    You will need to order the appropriate number of Square D QO remote controlled (motorized) circuit breakers separately. The MRTS panel contains the controller, but the breakers are installed in your existing panel.
