Product Details Supplier Info More products

Omniflex has more than 40 years experience in the design and manufacture of alarm annunciators and has been instrumental in their development from relay logic to microprocessor controlled SIL Rated Alarm Annunciators.

The aim of an alarm system is to prevent, or at the very least minimize, physical and economic loss to plant or people through operator intervention in response to a plant condition that has occurred thus making the necessary corrective action optimizing production.

Alarm management has new meaning in major process plant disasters of recent years, such as Buncefield, Chernobyl, BP Texas City, Bhopal and 3 Mile Island to name but a few.

Collaborative work by large process companies, vendors and industry organisations like the Electrical Equipment Manufacturers and Users Association (EEMUA) and the Instrumentation Society of America (ISA); accepting the need for an alarm management strategies; and applying new technology and standards to the process, companies can achieve multiple benefits. These include better productivity, quality improvement,  a more motivated and responsible staff, improved profitability and efficiency while minimizing the potential liability of management.

Definition of an Alarm

An alarm is classified as an event to which an operator must react, respond and acknowledge (not simply acknowledge and ignore) and no plant should have more than 6 such alarm occurrences an hour [EEMUA 191 guidelines].

If you have more than that you have got it wrong!

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.
