Short Definitions
Building Management System (BMS)
A platform that brings HVAC equipment, sensors, alarms, schedules, and operating data into one system for monitoring and control.
Gateway
A device or software layer that connects controllers, sensors, networks, or different communication protocols so data can move between them.
Fallback Demo
A locally stored, offline, or recorded version of the demo used when a live device, login, network connection, or cloud platform is unavailable.
What an AHR Expo Controls Demo Needs Behind the Screen
An AHR Expo controls demo may look like a dashboard and a few connected devices, but the live sequence can depend on controllers, sensors, gateways, computers, displays, network hardware, and connected HVAC equipment working together. A complete controls demo device list should also account for power supplies, signal cables, login credentials, local software access, and backup equipment.
Demo Component | Power Need | Data or Network Need | What to Check |
|---|---|---|---|
Controllers and control panels | Product-specific or low-voltage power | Direct I/O, fieldbus, gateway, or local network | Keep terminals, controls, and reset access available |
Sensors and field devices | Battery, low-voltage, loop, or controller-supplied power | Direct input, fieldbus, wireless link, or gateway | Confirm how the input reaches the controller and dashboard |
Gateways and routers | Continuous power | Local network, wired internet, or both | Keep devices concealed but within technician reach |
Computers and demo laptops | Reliable power or charging access | Local network, wired internet, or offline environment | Test logins, permissions, software, and backup files |
Dashboard screens and touchscreens | Screen power and video or data connection | Depends on the computer, controller, or media source | Check readability and response from the visitor position |
Connected HVAC equipment or simulated loads | Product-specific power and controls | Direct control, gateway, local network, or simulated input | Test the complete hardware-to-dashboard result |
Spare cables, adapters, batteries, chargers, and a backup computer should be treated as part of the BMS demo booth setup, not as last-minute accessories.
Plan Power Around the Live Controls Demo
A controls demo may depend on dashboard screens, computers, controllers, gateways, routers, connected HVAC devices, demo lighting, and backup hardware. Power planning should follow the approved workflow so each critical device remains available throughout the presentation, while chargers and spare equipment stay within reach.
Keep the Live Demo Chain Powered
Controllers, network devices, computers, screens, and connected equipment used in the live sequence need continuous power. Critical components should not all depend on one failure point, especially when a single interruption could stop the controller-to-dashboard workflow or delay troubleshooting.
Leave Access for Charging and Reset Work
Tablets, backup laptops, batteries, adapters, and spare devices may only need charging access, but those points should remain reachable after counters, screens, and storage are installed. The same device map should carry into trade show booth design and engineering, where screen positions, counter openings, cable routes, and service points are coordinated before production.
