PURPOSE AND SCOPE OF APPLICATION

Sound signaling devices are applied in areas, where sound and speech signals for warning are required, as well as in areas with potentionally explosive atmosphere.

Explosion-proof electrodynamic sound signaling device PGZ-SIRENA1 is intended for continuous round-the-clock operation in a stand-by mode (possibility to send sound alarm signals) in security, fire and other signaling systems. Maximum level of sound pressure (sound signal is modulated as per the apmlitude) at rated supply voltage is not less than 114 Db. Pattern of direction for sound signaling device PGZ-SIRENA1 is circular.

By default, the device is supplied without mounting bracket. To add mounting bracket to the assembly, /SKOBA option must be specified in the marking when ordering.

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.
