FIRE SAFETY FEATURE Enhanced fire and gas safety systems


performed when smoke, heat, and/or gas is detected, an essential aspect of any FGS application, have been added to the ProSafe-RS engineering functions. Standard FGS faceplates have been added for the integrated display of smoke, heat, and gas detector information such as gas concentration level and device status. In addition, the I/O module has a new function that can reset the detector that sends smoke and heat detection signals to the ProSafe-RS system. This eliminates the need for a reset circuit to restore communications after an abnormality is detected, thus reducing both the size of the hardware and its initial cost. With these enhancements, the ProSafe-RS is easier to adopt and use in FGS applications. Yokogawa provides an N-IO (Network-

n the oil, natural gas, petrochemical, chemical, and other energy and basic


materials industries, various safety measures must be taken to prevent accidents and protect the environment. This includes the use of a safety instrumented system, which can secure plant safety by functioning as an emergency shutdown system (ESD) that detects abnormal conditions and safely initiates emergency shutdowns, and by functioning as a fire and gas system (FGS). Yokogawa’s ProSafe-RS safety


instrumented system can be integrated with the CENTUM VP integrated production control system and is widely


used mainly in ESD applications all over the world. Since releasing this system in 2005, Yokogawa has continued to strengthen its functions to satisfy a variety of customer needs. In response to the rising need for FGS solutions, this latest release includes features that make it easier to adopt and use this system in such applications. And by adding a new input/output (I/O) module and enabling the use of an alternate control network topology, users have a greater range of choices in their ESD and FGS applications. Cybersecurity has also been strengthened. Software components that define the operations and functions to be

As most safety instrumented systems rely mainly on digital I/O signals, the company has added a new I/O module to its lineup that is used for only the input or output of digital signals. This new module reduces the total cost of ownership for users. For the Vnet/IP real-time control bus,


ProSafe-RS has relied on the star network topology, in which all devices are connected to a central hub. Vnet/IP is a control network developed by Yokogawa that features high reliability and quick response. Vnet/IP complies with the IEC61784-2 international standard. The new ProSafe-RS is also compatible with the ring topology, in which devices are connected to each other in the shape of a ring. This feature affords customers greater flexibility when configuring their systems.

EXTINGUISHANT CONTROL PANELS PROTECT NEW FACILITY


Kentec gas extinguishing fire safety panels are playing an important role in helping to protect Specsavers’ new £12 million manufacturing and distribution centre. A new fire safety system, designed and installed by Leader Systems, comprises Kentec K11031 M2 Sigma XT Automatic three zone Extinguishant Control Panels with Apollo conventional Series 65 devices plus conventional sounder/beacons and bells from Klaxon Signals. Kentec’s Sigma XT is designed to comply with the requirements of EN12094-1,


EN54-2 and EN54-4. It features three detection zones as standard, where any zone or any combination of zones can be configured to release the extinguishant gas and allows delay in first stage sounder and detection to be configured, with an instant release facility by using the manual release option. The Kentec Sigma XT is compatible with intrinsically safe barriers, which makes it ideal for use in hazardous areas. Kentec were the first company to introduce an EN12094-1:2003 compliant extinguishing panel and were able to apply the CE mark showing


compliance with the Construction Products Directive to any type of fire control panel. Kentec
