Visual alarm deadline met

Designed to protect the deaf or hard of hearing and those working in areas of high ambient noise, the BSI introduced EN 54-23 in June 2010 in order to set stricter guidelines on the installation and performance requirements of Visual Alarm Devices (VADs).

 

Compliant products are only permitted to emit a red or white light and are classified into three categories based on their intended application – ceiling mounted devices, wall mounted devices and an open class category.
