Product details
The FireClass FC440CAVB (576.440.016) is an addressable base sounder beacon VAD (visual alarm device) for FireClass addressable fire alarm systems. It is loop powered and driven from an addressable control panel, and as a ceiling-mounted base it provides a mounting for a fire detector (or a B-CAP blanking cap). Tones, volume, beacon flash and status monitoring are configurable from the control panel, and every unit has a built-in two-port loop short-circuit isolator.
