ABSTRACT Brief Description The Advanced Discovery System (ADICOS) is used for early detection of fires in industrial environments. It is comprised of various separate detector units. With aid of suitable arrange- ment and parameterization the system meets a specified detection goal, without being sus- pectible to interference.
ABOuT THIS MANuAl About this manual Objective This manual describes the special requirements on installation, wiring, commissioning, and operation of ADICOS detectors for explosive atmospheres. They are exclusively addressed to knowledgeable specialist personnel (–› Chap. 2, Safety instructions). Explanation of symbols This manual features a continuous structure for best possible comprehension.
SAfETY INSTRuCTIONS Safety instructions ADICOS HOTSPOT-X20 detectors for explosive atmospheres ensure operational safety as- suming proper installation, commissioning, operation, and maintenance. for this purpose, it is absolutely required to completely read, understand, and follow these instructions and the safety information contained. WARNING! Installation and operating errors can lead to fatal and severe injuries and dam- age to the industrial plant.
SAfETY INSTRuCTIONS Personnel qualification Any work on the control may only be performed by qualified personnel. Persons, who can per- form work on electrical systems and recognize possible dangers based on their professional education, knowledge, and experience as well as knowledge of the applicable provisions, are considered qualified personnel.
