📊 False alarms are expensive. Unnecessary emergency service calls waste time.
A trouble signal shouldn't cost you an emergency fire department dispatch fee and a supervisory signal shouldn't cause confusion.
Your fire alarm panel isn't trying to confuse you, it's telling you three very specific things:
🚦 Alarm - fire/smoke threat. Dispatch emergency services.
🚦Supervisory - A vital system issue (like a closed sprinkler valve). No fire, but an operational issue.
🚦Trouble- An electrical glitch within the system's own hardware (like a dead battery).
