PAGA System

The ZIZTEL Public Address & General Alarm System (PAGA) has been designed specifically for the Oil & Gas industry.

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.

The ZEST PAGA System is specifically developed for use in aggressive operating industrial / marine environments including potentially hazardous atmospheres. ZEST 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.

Unlike many of our competitors we believe that software should not be part of the critical path in the design of a PAGA life safety system, to this end a highly robust static kernel is employed which meets the requirements of compliance with SIL level 3. The Ziztel PAGA design therefore eliminates risks associated with latent software bugs, system re boots and possible code corruption due to ‘brown outs’. Ziztel ZMIS core [link to ZMIS data sheet] provides the operator with ultimate PAGA management both locally and remotely (ZMIS Global), the application is an integral part of ZEST and is designed in house by our team of highly experienced engineers.

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 solutions.

The ZEST 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 ZEST 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. ZADS 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.
