PURPOSE AND SCOPE OF APPLICATION

Explosion-proof light and sound signaling device PGSK03 is intended to send sound and light signals with the purpose of indication of operation modes of the equipment and to draw people‘s attention in emergency and other situations.

Piezo-siren is used in PGSK03 signaling devices for generation of sound signals. 8 light emitting diodes of high brightness are used as a source of light signals. Power supply can be selected depending on the version – 12, 24 V DC and ~220 V AC.

PGSK03 explosion-proof signaling device has 3 operating modes:

• Stand-by mode – green indicator is ON, indicating that the device is switched on and ready for operation;

• Warning mode – intermittent mode for sound and light signalization (duration of the impulse – 0,5 s - 1 s; interval between signals - 0,5 s - 1 s);

• Emergency signalization – constant mode for sound and light signalization.

Combination of lights signals is selected upon customer’s request.

Full production cycle from foundry patterns to finished products is carried out by explosion-proof equipment plant “ZAVOD GORELTEX” Co. Ltd. (former “CORTEM-GORELTEX” Co. Ltd) in the territory of the Russian Federation.

Scope of application – outdoor and indoor hazardous areas 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.
