PAGA/MAIN BROADCAST SYSTEM
The ZIZTEL Public Address & General Alarm System (PAGA) has been designed specifically for high criticality applications including the Oil / Gas industry and the Military; use in less demanding markets is therefore readily accepted.
As with any life safety system the purpose is to deliver a product that is efficient, robust and resilient. Our systems extend from simple non duplicated single path architectures to complex networked fully duplicated redundant A+B N +2 solutions with addressable field devices.
The delivery includes bespoke project management and comprehensive documentation and drawings. Clients are welcome to witness Factory Acceptance Testing.
Full site support is available post-delivery ensuring the system is commissioned and maintained to meet its full design potential and life cycle costs are minimised.

Advantages of Ziztel PAGA system
Prime features of the system include:
- Energy Efficiency – consumes much less power than conventional designs.
- Space Saving miniature 3 unit high power 350Watt amplifier cassettes – significantly reduced 19 inch rack foot print.
- Touch screen management Ziztel GUI enabling rapid fault finding and remote supervision worldwide.
- Class G amplification – live pluggable – rapid service no EMC or network matching risks.
- PC configurable high security operating platform – mission critical life dependent applications – no chip exchanges required.
- Intelligent Addressable Speaker - IAS – supervision of individual loudspeakers and flashing beacons.
- Pressurised Exp ATEX certified fully explosion proof solutions.
The PAGA system is designed to reliably operate for extended periods of time and meets the strictest conditions specified by leading authorities including Bureau Veritas, ABS, RMRS and DNV.

The PAGA System is specifically developed for use in aggressive operating industrial / marine environments including potentially hazardous atmospheres.
The Ziztel PAGA is a purpose designed system targeted at Life safety critical applications, the levels of integrity required for such systems cannot be met by general purpose equipment or hardware primarily designed for intercom applications.
Typical Ziztel high integrity PAGA system configuration – note that the entire critical path is fully duplicated including microphones, controls, indications, management, amplification and field equipment. There are no common mode failure points.
The central equipment extends either loop based or radial / star wired field circuits to loudspeakers, flashing beacons and microphone access units where applicable.
When loop wired cable architectures are specified the package automatically provisions automatic self-healing capability to ensure uninterrupted service in event of field cable conductor discontinuities as well as automatically providing an early warning of any system deterioration.
The central rack allows optional connection to other site systems; examples include: - telephone PABX , VHF/UHF Radio systems, SCADA, Fire and Gas / ICSS, ESD Emergency shut down, Supervisory / fault reporting, Event Recording and Entertainment Systems.
A PAGA package can be supplied in a number of system architectures depending on site criticality:
The Ziztel PAGA also includes the possibility to interrogate each loudspeaker (and flashing beacon) connected to the system either locally or remotely. Intelligent Addressable Speaker - IAS is a secure non-invasive automatic testing sub system which eliminates routine maintenance patrols enables simple adjustment of sound pressure levels delivering greatly enhanced levels of integrity and major cost savings.
