VADs are used to supplement sounders, providing an effective means of alerting and evacuating occupants of the building, as part of its fire safety strategy. Regulations and codes of practices recommend that they should be installed in places where audible devices alone would be ineffective, or, where they are simply undesirable. Installation of VADs has been mandatory since January 2014 and, with the introduction of the EN54-23 the use of VADs has grown considerably.

FC440AV

The FC440AV range of compact addressable wall sounders with a Visual Alarm Device (VAD) includes three models with the same low current and high-output specification. There are red and white body indoor models plus an IP-rated version for either outdoor or harsh environment applications.

FC440AVB and FC441AVB Addressable Sounder VAD Bases

Specifically, for use with the FireClass addressable detectors. The bases are available as fire alarm sounders with Visual Alarm Device in two power outputs, standard and high. 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 two-wire digital loop provides the power and communications for the sounder, VAD, and detector.

FC442AVB Addressable Open Class VAD Sounder Beacon

For use with the FireClass addressable detectors. The base incorporates a fire alarm sounder that carries its own address so it can be monitored and controlled from the fire alarm control panel, which is independent of the detector fitted to the base. The two-wire digital loop provides both power and communications for the sounder and detector.

FC445CAV and FC440CAVB Addressable wall sounder VAD and sounder VAD base

These are compatible with FC510 and FC520 panels and should be used only with those panels. The panel display will show device type of the previous FC410LPBS and FC430LPBSB.
