he ST7-HV panel is intended for the protection of life, process plant and equipment. It is designed to meet the requirement for reliability and availability particularly for the companies that operate process plants, refineries, energy generation facilities, onshore/offshore oil and gas platforms, chemical plants, marine and commercial industries where it shows excellent system resilience and resistance to electromagnetic disturbances. The ST7-HV panel functions as a safety PLC but fulfils all insurance requirements for dedicated safety systems and is certified by international laboratories to perform the required protection functions in compliance with the applicable standards and/or regulations. The panel is composed of a CPU and dedicated control cards which have their own “intelligence” and are programmed for monitoring, control and alerts for active/passive fire protection, gas detection, CCTV and intruder detection systems. External communication is achieved using standard protocols, such as Ethernet TCP/IP and Modbus. The systems are installed within dedicated19” data racks.

Applications |
The ST7-HV panel is commonly used in :
- Automatic fire suppression and extinguishing control systems. Conforming to the Construction Products Directive (CPD)
- Integrated systems, including fire, intruder/burglar alarm, CCTV along with input/output control function for other peripheral services.
- Safety Security systems, where panels operate, as master or slave units, on communication networks (of a fibre optic and fault tolerant type, too) and are connected to DCS through the protocol;
- Fire protection systems with special voting and redundancy logics, also in accordance with the recommendations of the NFPA 72 standard.
- Gas detection and measurement systems, ATEX-certifiable, capable of interfacing any 4-20 mA output toxic or explosive gas detectors. All of these functions can coexist, or be configured to meet specific customer requirements.

Features |
- Hot backup redundant CPU’s, Hot swap of all cards, including CPU’s, with automatic reconfiguration
- Redundant and looped communication bus between cards and CPU’s, Periodical automatic testing of card inputs and outputs
- Monitoring and Self-diagnostics of the main CPU and control cards allowing safe isolation of any malfunctioning controllers.
- CEI EN 50130-4 immunity requirements (EMC) widely exceeded. Display independent from base rack
