This document summarizes a seminar presented by EMS Radio Fire & Security on new technology. EMS has been in business since 1967 providing radio parts and later fire and security systems. They now employ 130 people in a 4,000 square meter facility. The seminar covered the EN54 wireless link standard for radio fire devices, key differences between this and the BS5839 standard, how EMS ensures quality factory production control, and applications of wireless fire technology such as for historic buildings, difficult installations, and temporary systems due to benefits like speed of installation and minimal disruption.
