Addressable Gas Detection Systems: 750/650

International Gas Detectors has introduced the TOCSIN 750 and 650 series addressable gas detection system that offers the best gas detection technology.

The systems use advanced addressable technology and offer features and benefits that have never been seen in the gas detection sector before. The combination of Sentinel+ protocol and two-Wire technology from International Gas Detectors allows users to save around 70% to 80% of the cost when compared to existing gas detection systems available on the market.

Third-generation gas detection technology is used by the TOCSIN 750 and 650 series addressable gas detection systems. Integrated with Sentinel+ communication protocol from International Gas Detectors, all sensors are linked to the system on a radial.

The nodes and detector are daisy-chained together through a two-core cable. The two-wire technology from International Gas Detectors is the world’s first technology that is not yet available on the market. The addressable systems provide an array of features that are advantageous to both end-users and installers.

Display Options

Equipped with a color touchscreen display, the TOCSIN 750 offers a user-friendly experience and provides a comprehensive visual of the status of the gas detection system. The color touchscreen shows each device or detector/node linked to the gas detection system. These are shown as bar graphs, displaying present gas levels and alarm thresholds.

When each channel is tapped, additional data about that device or detector/node is obtained. The touchscreen even shows the 'tag lines' of the sensor, enabling users to modify the name of every connected device/sensor, including its location; for instance, 'oxygen sensor in liquid Dewar room.'

Besides this, the TOCSIN 650 Series control panel is integrated with a 2 x 8 RGB color change display and jog wheel. The 2 x 8 display is rugged and is mainly used in heavy machinery and high-traffic areas, like process areas and plant rooms.

The TOCSIN 650 system offers a low-cost solution without affecting the capability of the system. Moreover, the 2 x 8 display allows only restricted access to the gas detection system.

If users find it difficult to select between the display options provided by International Gas Detectors, they can install a 7-inch color touchscreen display up to 1 km away from the main TOCSIN 650 series control panel and can still control the gas detection system from either display.

Service and Report Apps

International Gas Detectors has an array of apps that enable users to service the systems and also download system reports. This feature not only makes service easier and less time consuming but also makes sure that the system has been serviced properly because a report can be easily downloaded from the 750/650 gas detection system. International Gas Detectors offers platform-independent apps.

With the TOCSIN 750 and 650 series control panels, users can perform remote monitoring and third-party system integration.

'Information is key' in today’s digital age. The systems from International Gas Detectors allow users to remotely track the data and information from the gas detection system. Users can employ a 15-inch touchscreen human-machine interface [HMI] to display the data remotely. They can even use the 'Cloud-Based Data Acquisition' solutions available from International Gas Detectors to visualize the gas detection data on any device, anywhere.

A Resource Data Manager (RDM) provides another way to remotely track the gas detection system. A Global System for Mobile Communications (GSM) is yet another way through which text notifications and emails can be sent to specialized mobile numbers and email addresses with fault and alarm notifications.

The gas detection systems from International Gas Detectors enable third-party system integration, like Fire Systems and Building Management Systems (BMS).

Versatile and Expandable

The TOCSIN 750 and 650 series gas detection systems are the most expandable and multipurpose systems available on the market. The two control panel options enable up to 128 detector/nodes across four highways. On the whole, as many as 350 connected devices can be integrated into the systems.

Every highway uses a single two-core cable and the detector/nodes are daisy-chained together. All highways can be run up to 1 km and up to 3 km with the inclusion of boosters. With the 650 and 750 series controllers, users do not have to pay for extra capacity because every controller option is included with four highways as standard.

Sentinel+ Addressable Communication

The 750/650 addressable gas detection system uses the advanced Sentinel+ communication protocol from International Gas Detectors. Integrated with features, the Sentinel +™ 2-Wire technology is a sophisticated digitally communicating gas detection protocol available from International Gas Detectors. The system delivers rapid, error-free, and efficient performance and has been particularly developed to fulfill the special requirements presented by gas hazards.

The Sentinel +™ 2-Wire technology constantly tracks the health and integrity of both the detector and the cable in less than a second communication time. This feature ensures that users have a rapid and consistent gas safety system.

The system offers excellent flexibility to connect the gas detection system to interface to plant shut down hardware, send alarms, and communicate distinctly with Building Management Systems (BMS) and analogous systems.

The two-core cabling for both communication and power without polarity requirement means that cabling is reduced, thus decreasing system costs without compromise.
