Which protocol is commonly used to integrate building automation with fire alarm systems?

• A. BACnet
• B. OPC UA
• C. MQTT
• D. Z-Wave

Answer: (A)

When integrating building automation with fire alarm systems, the goal is reliable, standardized communication across diverse devices and vendors. BACnet is designed for building automation and control networks, providing a common way for devices from different manufacturers to talk to each other. It defines object types (like on/off signals and sensor readings) and services that let a building automation system monitor alarm states, receive events, and coordinate actions with fire safety equipment. Because fire alarm panels and BAS need to share real-time status and trigger coordinated responses (such as ventilation or door/ elevator control), BACnet enables this interoperability in commercial buildings. Other protocols exist—for example OPC UA, MQTT, or Z-Wave—but they don’t have the same level of industry-wide adoption and built-in suitability for integrating fire alarm systems within building automation, making BACnet the typical choice.
