Annunciators within the Omniflex range have been assessed in accordance with the requirements of the UK Nuclear Installations Inspectorate, which involved substantiating the safety certification of each instrument involved.

The Emphasis tool was developed to assist the nuclear site operators to achieve a common level of substantiation while eliminating duplication of effort.

All of the annunciators within the Omniflex range that have been assessed use the same technology and firmware version as used in the Omni8/16C, allowing the company to re-package the boards into custom-built housings and to offer direct-replacement annunciators for older third-party manufacturers’ units such as the Rochester UC30 and MPAS90 Alarm Annunciators, thus allowing these and other old annunciators to be replaced by an Emphasis-approved Annunciator.

Additional features of the Omniflex Annunciator range have also been approved, allowing for the addition of serial interface boards and soft-set mode, which is used for more advanced alarm annunciator functionality, providing flexibility in configuration.

The company was founded in 1965, formerly known as Conlog, specialising in process control, alarm/event management and instrumentation products and systems. In 1997, the original instrumentation business division of the company changed its name to OMNIFLEX Ltd.

Omniflex works across all business sectors including pharmaceuticals, hospitals, oil, gas, nuclear, water, electrical distribution and energy monitoring.

The company has its offices in the UK, South Africa, and Australia, and the company’s products are sold on five continents. Product ranges include well-known brands such as OMNI SIL alarm annunciators, OMNITERM SIL signal conditioning, MAXIFLEX intelligent remote terminal units (RTU) and I/O systems and the MAXILARM/Omni 4000 alarm/event management systems.

We bracket ourselves as a ‘remote monitoring specialist’, using data acquisition systems, with better than 1mS timestamp at the IO point (from several I/O up to thousands of I/O),  alarm event management including multiplexing systems, telemetry systems, Data2Desktop using standard web browsers, over varying forms of media and high-integrity (SIL1) annunciator systems.

A particular area that Omniflex is also very strong in is obsolescence issues on old legacy alarm annunciators systems. We have, in most cases, a solution for replacement of Rochester, Highland and Robinson’s annunciator systems. Our alarm annunciator systems have been substantiated by Sellafield for and on behalf of all the nuclear operators.

An area that we can offer customers significant cost savings is through the use of our CONET networking technology, which is supported by many of our RTU / PLC products. Using our CONET network technology allows existing installed cabling to be used therefore significant cabling/installation costs can be avoided. A typical example of this whereby our customer in the nuclear industry used our CONET technology, retained their existing cabling and infrastructure, saved them in the region of £1m on cabling and scaffolding.

As a worldwide supplier, OMNIFLEX provides technical training, back-up and application engineering support to a variety of industry partners including local distributors, value-adding resellers and systems integrators, to provide superior levels of service to the end user.
