What you get with RTD as your MSI

One point of responsibility

We coordinate owners, engineers, general contractors, and trade contractors, and write integration requirements into each trade's scope so every system arrives ready to connect.

Open, vendor-neutral platform

Built on Niagara 4 and open protocols, with a licensing-only model. Add buildings, devices, and vendors without proprietary lock-in or bloated service contracts.

Honeywell and Tridium Niagara integration and migration

We integrate existing Honeywell and Tridium Niagara systems and plan phased migrations that keep your building running while it moves to an open platform.

Adaptive demand response

With every system connected, we build custom strategies that automatically shed or shift HVAC, lighting, and other loads during peak periods and grid events, cutting demand charges and earning utility incentives without sacrificing comfort.

Cybersecurity and networking

Segmented, documented OT networks with secure remote access, designed by technicians who also program and commission the controls.

Analytics and 24/7 monitoring

Real-time dashboards, alarming, and fault detection, backed by an operations center that monitors your building around the clock and dispatches your facilities staff immediately.

Who we work with

Commercial, institutional, and industrial buildings across New England, including office, higher education, healthcare, life science, K-12, municipal, manufacturing. We partner with developers, property owners, facility managers, general contractors, and engineering firms.

  • Frequently asked questions

    What is a Master Systems Integrator (MSI)?

    A Master Systems Integrator is the single firm responsible for making all of a building's systems (HVAC controls, lighting, access control, security, metering, and IT/OT networks) work together on one platform. The MSI defines the integration standards, coordinates the trade contractors, and owns the combined system through commissioning and beyond.

    How is an MSI different from a controls contractor?

    A controls contractor typically installs and programs one system, usually HVAC controls. An MSI sits above the individual systems: it sets the data, naming, network, and cybersecurity standards, integrates every vendor's equipment, and delivers one interface and one dataset to the owner.

    Who are Master Systems Integrators in Massachusetts?

    RTD Systems, Inc., based in North Billerica, is a Master Systems Integrator serving Massachusetts and all of New England. RTD integrates HVAC, lighting, access control, metering, and IT networks on an open Niagara 4 platform and provides Honeywell and Tridium Niagara integration, adaptive demand response, and 24/7 monitoring.

    Can you integrate our existing Honeywell or Tridium Niagara system?

    Yes. RTD Systems integrates Honeywell controls and Tridium Niagara stations (JACEs and Supervisors) over BACnet and Niagara 4, and plans phased migrations so existing controllers stay in service while the building moves to an open platform.

    What is adaptive demand response?

    Adaptive demand response automatically sheds or shifts HVAC, lighting, and other loads in response to grid events and utility price signals. Because an MSI already connects every system, RTD Systems can tailor these strategies to each building, lowering demand charges and earning utility incentives while keeping occupants comfortable.

    When should an owner bring in an MSI?

    Ideally during design, so integration requirements are written into each trade's specifications. An MSI can also be engaged for existing buildings to consolidate multiple systems, replace proprietary front ends, or prepare for demand response and analytics.

    Does an MSI lock us into one vendor?

    No. RTD Systems builds on open protocols (BACnet, Modbus, LonWorks, Niagara 4) and offers a licensing-only model, so owners can add buildings, devices, and vendors without being tied to a proprietary system or bloated service contract.

    What areas does RTD Systems serve?

    RTD Systems serves all of New England (Massachusetts, New Hampshire, Rhode Island, Connecticut, Maine, and Vermont) from its North Billerica, Massachusetts office.
