FC441AVB Addressable Sounder Base VAD Hi
The FC440AVB and FC441AVB are addressable sounder bases with a visual alarm device specifically for use with the FireClass addressable detectors. The bases are available as fire alarm sounders with visual alarm device (VAD) in two power outputs, Standard and High. The High power option provides more coverage for the VAD compared to Standard.
Each has an address so they can be monitored and controlled from the fire alarm control panel, which is independent of the detector fitted to the base. The power and communications for the sounder, VAD and detector are provided by the digital loop. This helps to reduce installation costs as no additional wiring is required.
