November 4, 2025 — In today’s fast-moving world, building owners face increasing pressure to reduce energy use, meet sustainability goals, and improve occupant comfort — all while managing tight budgets. But if your facility still relies on a legacy building automation system (BAS), achieving these goals can seem out of reach.
The good news? You don’t have to start from scratch.
S4 Integration Solutions believes that legacy systems — especially Johnson Controls Metasys N2 networks — can still deliver value when paired with modern, open protocols like BACnet. S4IS’s BACnet N2 Integration product bridges the gap between your existing N2 devices and today’s smart building platforms.
Why upgrade instead of replace?
Replacing a BAS is expensive, disruptive, and often unnecessary. In many buildings, field-level devices (like sensors, actuators, and controllers) are still perfectly functional. The problem lies in their inability to communicate with modern building management systems (BMS) or value-added applications.
The S4IS BACnet N2 Integration unlocks this potential by:
- Preserving your investment: Continue using your N2 devices while gaining access to powerful, BACnet-based front-end systems.
- Reducing downtime: S4IS integration installs with minimal disruption to your building operations.
- Accelerating ROI: Start benefiting from energy analytics, fault detection, and modern UI/UX immediately — without waiting for a system-wide upgrade.
- Automating the process: S4IS technology auto-discovers your N2 network and creates BACnet-compliant representations of your existing devices — fast, efficient and accurate.
Built for scalability and performance
Unlike other gateways, the S4IS BACnet N2 Integration was engineered to offer:
- Network management-grade performance
- Full visibility into system health and device status
- Deep configurability without complexity
Whether you’re managing a single building or an entire portfolio, the S4IS integration platform helps you meet your operational and energy goals faster.
A smarter path forward
Modernizing your BAS doesn’t have to mean tearing it out. With S4 Integration Solutions, you can evolve your system at your pace — cost-effectively and without sacrificing reliability.
