No need to emphasize the importance of public address and general alarm system on industrial enterprises – duly designed PAGA system is not only an effective tool in technological process control but also, and that is the most important, can prevent people’s injuries or even save their lives in case of emergency.

The basic functions provided by PAGA systems are:

1. Zonal and general announcements in  manual or automatic mode
2. Intercom or Page-party communication between subscribers
3. Sending the alarm signal to the concerned services in case of emergency (fire brigade, police, civil defense)
4. Conference communications
5. Entertainment programs (music, radio) broadcasting
6. Crane communication systems

The highest reliability of the proposed systems is achieved by the following features:

1. Advanced speech quality due to extended bandwidth of the speech – up to 12 kHz
2. Simplex communication mode for the areas with extreme levels of surrounding noise
3. Permanent monitoring of the system operation
4. No single point of failure – distributed architecture with all the critical points of the system duplicated (A/B) or reserved (N+1)
5. Integrity with other telecommunication systems (PBX, radio, F&G, CCTV)
6. Special housings for equipment usage in extremely harsh conditions, proven by international certificates (CENELEC, ATEX, NFPA, CSA) issues by key world agencies (UL, DNV, FM, CUL, BASEEFA)
