PURPOSE AND SCOPE OF APPLICATION
PGS-IT34 explosion-proof sign is used as signage, for giving light alarm signals in hazardous areas in presence of combustible gases and dust to regulate a person‘s behavior under normal conditions and in emergency situations. It is used in fire alarm systems and automatic fire fighting systems.
Explosion-proof sign PGS-IT34 has two modes of lighting: constant and intermittent with frequency of ~1.5Hz (only for incandescent and LED lamps). Lighting mode depends on selection of circuit.
Scope of application - hazardous indoor and outdoor areas in accordance with explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) and areas hazardous with combustible dust ignition, as per GOST IEC 61241-3-2011, dangerous production facilities of I, II, III, IV hazard classes under supervision of Rostekhnadzor and national supervisory bodies of the Customs Union and the CIS countries.
