Modern buildings are complex ecosystems, housing multiple systems that need to work together seamlessly. From HVAC and lighting to security and energy management, each system generates data and requires coordination.
At Tyrrell Systems, we specialise in Master Systems Integration (MSI), bringing together these fragmented technologies into intelligent, responsive ecosystems. We coordinate systems like BMS, IoT, lighting, fire, security, and energy to create buildings that are not just smart, but truly intelligent.

Comprehensive solutions designed to simplify complex integrations and deliver exceptional results
We simplify complex multi-system coordination by acting as the single, accountable interface between all building technologies — saving you time and reducing integration risk.
We ensure all building systems (BMS, IoT, lighting, fire, security, metering) are properly integrated, tested, and handed over — reducing post-completion issues and delays.
From design to commissioning, we support you with technical input, system architecture advice, and clash avoidance before problems arise onsite.
Our integration expertise avoids duplication, miscommunication, and system conflicts — helping keep programmes on track.
We help you meet client ESG, smart building, and compliance requirements — making your project more valuable.
We understand how contractors work — with in-house engineers, documentation, and support built for your delivery model, not against it.
