A Success Story

From flat roof production to the development of innovative fire detection – with strategic initiatives Klaus Esser started his success story in 1973 and invested into manufacturing of fire systems. He thus laid the foundation of ESSER’s worldwide reputation as a leading and innovative brand for fire detection. Until today ESSER develops and produces high-qualtity, reliable fire alarm and voice evacuation systems – since April 2005 as part of the Honeywell Group.
