Discover the latest advancements in fire safety with Building Research Establishment (BRE)'s newly published research on the effectiveness of Visual Alarm Devices (VADs). Sponsored by the Fire Industry Association (FIA) and its members, this comprehensive study explores five critical factors influencing VAD performance, offering essential insights for updating fire safety standards.
Since January 2014 visual alarm devices (VAD) should meet the requirements of EN 54-23. This has led to some confusion regarding the use of combined sounder beacon devices where the beacon element does not comply with EN 54-23. The use of such devices is acceptable while understanding that the beacon element must be regarded as a supplementary visual indicating device (VID) and is not expected to provide a primary alarm warning signal for alerting or evacuating the occupants of the building.
The requirements of any fire detection and alarm system should come from the determinations of a fire risk assessment and the emergency evacuation procedures. If this risk assessment does not identify the need for a VAD then combined sounder beacon bases can provide a supplementary visual indication that will increase the awareness of people to an event. However manufacturers should make a clear declaration that the device is not to be applied as a visual alarm device as defined by EN 54-23.
