Angst+Pfister has concentrated its safety technology program on the theme of "illuminated safety systems", containing a very diversified and high-standing range of products. This comprises: (a) stationary emergency and warning lamps, mobile emergency lamps, monitoring equipment for emergency lamps having a single battery and special lamps for use in potentially explosive environments, and (b) a series of emergency electricity supply systems. This extends from simple centralized emergency battery electricity supply systems to complete plants with microprocessor controlled functional control systems and separate monitoring of individual lamps, without the need for additional data transmission lines.
