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.
