Fire Alarm Function Testing Workstation

Simulate activating the devices in your design and watch the notification appliances respond in real time — flashing strobes, evacuation tones, and live status updates. A safe way to understand cause-and-effect before you're on the jobsite.

Simulation for training only. Real fire alarm testing must follow the manufacturer's instructions, NFPA 72, and your AHJ — and must never be performed on a live system without proper notification and authorization.

Real-World Scenarios

Case studies from the field. Read the situation, decide what you would do, then reveal each step to compare your plan against a guided answer.
