The system execution employs a fully duplicated mission critical high security architecture which features ZMIS supervision and management enabling remote control and interrogation. Unlike other PAGA systems on the market today the Ziztel ZEST core operation is static with no dependence on software / code which ensures compliance with the requirements of SIL Level 3 and is commensurate with a high integrity PAGA system.
The package features a ‘proper’ A + B architecture, note that IP based PAGA solutions alone cannot achieve a truly fault tolerant delivery compatible with a prime life safety system.

New product release. The ZXM032 is a solid state micro controlled speech storage device. The unit can store up to 100 x voice messages each held in secure non-volatile memory. The ZXM032 plugs into a Ziztel ZX100 PAGA control processor and delivers a menu of pre-recorded emergency or routine voice messages under control of either the operator and / or the site fire and gas detection package. Cause and effect is readily configured in the host management subsystem to allow zonal distribution, alarm tone augmentation (interleaved MESSAGE / ALARM TONE / MESSAGE ..) or site wide pre-defined voice instructions.
Ziztel DAS04Ex is a Zone 1 ATEX certified Explosion proof distributed intercom station which operates on a network basis thereby eliminating the requirement for a centralised exchange or switch. The unit is primarily intended to provide secure 'last ditch' open channel emergency voice communications between critical muster point positions on an offshore installation. To this end the unit incorporates self-contained integral no break supply autonomy, amplification and system management and is arranged so that there is no dependency on other equipment or other stations. The DAS01 Ex is supplied with ZAP10-02-11 explosion proof noise cancelling microphone and DSP15 EXMN explosion proof projector horn which together assure high speech intelligibility in potentially hazardous severe environmental conditions. Where the unit must provide efficient operation in ambient noise exceeding 85dBA sound pressure level the Ziztel AH23-60079 acoustic hood provides both excellent back ground noise rejection as well as additional shelter for both the equipment and user. The station is interconnected to other DAS04-Ex subscribers via a simple single pair cable which is arranged on a secure loop wired basis, up to 50 x DAS04-Ex stations can be connected to a single highway.
The Nghi Son Refinery and Petrochemical Complex is located in Thanh Hoa Province in North Vietnam, around 200 kilometers south of Hanoi. As Vietnam's largest oil refinery, it is expected to contribute more than 30 percent of Vietnam's demand for petroleum products. The new refinery will include a petrochemical complex, energy facilities, pipe line and storage facilities. It will produce products such as gasoline, diesel, and jet fuel for the local Vietnamese market, together with other products for sale in neighbouring countries.
Ziztel were selected to supply the audible alarm sounder / visual flashing beacons necessary to ensure signalling in high noise areas of the plant.
Management is provided by a network of sounder / beacon drivers, TCA-01X, which are locally powered to provide amplifier and control outputs to dedicated 100 V line loudspeakers and xenon discharge lamps. The TCA-01X outstation is distributed over the site and includes both ATEX certified Zone 1 and safe area weatherproof variants.

Ziztel Integrated Page Party and PAGA package combines five party lines enabling full duplex handset communications, zonal voice paging and site wide emergency alarm and speech broadcasts. The system is based on the Ziztel PPX page party solution and is shown undergoing final FAT checks at our manufacturing facilities in Nottingham England in readiness for air freight to YPFB Ammonia and Urea complex Bolivia. The development is the largest project of industrialization of natural gas so far undertaken in the country.
The state oil company YPFB, stated that plant is designed to produce 650 thousand tons of ammonia and 725 thousand tons of urea and should be operational in the second half of 2015.
Many sites are subject to requirement for expansion of their existing PAGA system, this can be very costly due to either complete re fit of the existing equipment(s) or non-competitive unrealistic quotations for upgrade / renovations from the respective vendor.
A cost effective alternative is available from Ziztel enabling retention of major parts of the established system and allowing the operator to have a choice. The Ziztel X PAN-100 enables the operator to seamlessly interface his current PAGA package to a Ziztel system thereby taking advantage of the benefits of new technology within constraints of possible site expenditure.
The X PAN-100 enables safe and secure extension of almost any vendor’s PAGA system to a Ziztel package. The level of integration / expansion depends on site requirements and systems are tailored to suit the client technical / commercial specification and budget. The final package is designed to provide a fully supportable, maintainable and, most of all, safety critical solution.
The X PAN-100 sub system is already fitted, proven and commissioned on Middle East Petrochemical sites, saving considerably over the complete re installation of a replacement PAGA system . Contact Ziztel Sales for further information.
