Hazardous areas often require the use of optical signals for warning or information purposes. The EExII strobe light dSLB21 offers both of these signalling features. It is designed for continuous operation. If the supply voltage is turned on, the Strobe Light dSLB21 is activated. The device is available in several versions with various levels of operating voltage and flash energy and various signalling colours. The stable, glass-fibre reinforced polyester (GRP) housing is made to the IP66 degree of protection and may be used indoors or outdoors. The II 2 G EEx de IIC T6 protection class enables the unlimited use of the signalling device in all hazardous areas, zones 1 and 2. The flameproof enclosure and the "increased safety" type of protection of the terminal room guarantee hazardous area protection. The upper part of the flameproof enclosure, which contains the flash electronic and the mounted flash tube, consists of a transparent Makrolon-cap. An inner cap lends colour to the light. The housing consists completely of GRP. Thus the device is protected against corrosion, and fulfills the requirements of contact safety class II. An equipotentiel bonding is not required. All outer fastening parts are manufactured in noncorrosive materials.
