PURPOSE AND SCOPE OF APPLICATION

Explosion-proof sound signaling devices PGZ-POST are special-purpose signaling devices intended for application in hazardous areas in security and fire alarm systems and other signaling systems. Explosion-proof light and sound signaling devices PGZ-POST are intended for continuous round-the-clock operation in a stand-by mode (possibility to send sound alarm signals) in hazardous areas of industrial and construction facilities where flammable gases and dust are present. 

Explosion-proof PSGE01 piezo-siren is applied as a source of sound signal in signaling devices PGZ-POST, PGZ-POST-P, PGZ-POST-N. Maximum level of sound pressure is 108 Db. The piezo-siren supplied with 220V signaling device is additionally completed with a power block installed inside the signaling device.

Scope of application – outdoor and indoor hazardous areas and pits non-hazardous with gas or dust, as per explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996), regulating application of electrical equipment in hazardous and non-hazardous areas at dangerous production facilities of I, II, III, IV hazard class supervised by Rostechnadzor and national technical supervision bodies of the CIS countries.
