When the needs of our customer are fully understood, the project will be forwarded to our Projects office. Here, a team of dedicated engineering professionals will design a panel and building management system that will entirely meet the brief given. It is here that panel wiring diagrams are drawn up, with the building and final installation fully considered.


At MCA Systems, our design and manufacturing of control panels is carried out in our very own specialist assembly facility by a team of highly skilled and experienced engineers in Bangor, County Down. We can provide control panels to suit any requirement from small wall mounted panels to floor standing panels to multi-compartment form 4 motor control centres. The panels are manufactured with the highest quality components (Carlo Gavazzi, Eldon, Schneider, Siemens, Socomec, Weidmuller) in accordance with current electrical standards. Quality control and full bench testing is carried out before any control panel is dispatched to site so you can always be assured of the finest workmanship.


Once installed, our skilled engineers will attend site to begin commissioning your bespoke bems system alongside other disciplines, always with a view to completing the project on time to ensure a smooth building handover.

Building Management System 


Building Management System (BMS) is a computer-based control system installed in buildings that controls and monitors the buildings mechanical and electrical equipment such as boilers, pumps, air handling units, cooling plant, lighting, metering, fire and security systems. HTML5 graphical interfaces allows the BMS to be viewed/controlled within the building or remotely via PC, tablet, iPad, iPhone devices.

energy management systems 


Arrigo’s innovative energy management platform gives you the combined power of all data collected from a building by the control system. By connecting to the Arrigo EMS cloud service, you can easily access all building data and follow up on results gained from various actions in real time. The system gives you quality-assured analyses and forecasting without any manual input, helping you save valuable time. Arrigo makes it easy for building owners to see tangible results from various actions and implementations, helping them gain control of their energy consumption. In the long run, using Arrigo can contribute to greater cash flow and increased building asset values.
