  • Finally, a single SIL3 certified safety system that combines multiple related systems into one! Fire Extinguishing, Fire/Smoke Detection, Flame & Gas Detection, Security & Access Controls, and CCTV Cameras/DVR with an intuitive Supervisory HMI and full connectivity to PLC, OPC Server, and SCADA Systems.

    The HS81-HS system has been designed to meet the highest industrial functional reliability and availability requirements, particularly for the companies that operate in the field of energy production and transformation, where it shows excellent resistance to electromagnetic disturbances and a continuous operability in difficult environmental conditions. Its capability is demonstrated by the compliance with the requirements of fault tolerance set by the International Standards IEC 61508, and because of this compliance, it has obtained the level SIL3 (Safety Integrity Level 3) certified by TÜV Rheinland.


    • Flame and Gas detection systems
    • Automatic fire extinguishing systems
    • Addressable analog detection systems with multiple protocols
    • Integrated systems (fire extinguishing, CCTV, alarm, etc…)
    • Network systems among panels or with DCS and SCADA through Modbus, Ethernet and OPC Server

    All functions and features described above can co-exist in the same system or can be fully customized according to the customer’s needs.

  • • The HS81- HS fulfills all these functions: Safety PLC for F&G detection, addressable fire detection panel for general purpose buildings, fire panel for extinguishing systems, with complete system HMI interface

    • SIL2 and SIL3 certified - high availability and fault tolerance

    • Hot swappable & redundancy: power supplies and all cards, including CPU’s, with automatic reconfiguration

    • Addressable and Conventional, Distributed Intelligence - modular, sizeable to need

    • Automatic self-diagnostics and fault signalling of cards, I/O and CPU, automatic safety disabling of malfunctioning cards
  • The HS81-HS panel is a programmable Fire and Gas Controller suitable for safety and security installations with a technologically high economic content.

    What application is the system designed for?
    With the HS81-HS panel, fire & gas detection, intruder alarms, smoke detection & fire suppression can be integrated within O&G facilities, energy plants, petrochemical industries, naval, military and public installations.

    How is the system composed?
    Externally, the panel HS81-HS is similar to a safety PLC; it is composed of electronic PCB cards mechanically compatible, which are inserted in 19” racks. The panel HS81-HS can have from 1 to 10 racks, each rack has 13 card slots. In addition to the versions customizable for clients, the UL version has a case with 6 racks, while for the European market, 3 other versions are available:

    HS81-HS/1R: Base Rack + 1 card rack, wall-mounting cabinet, L=600 H=700 P=400 mm

    HS81-HS/2R: Base Rack + 2 card rack, wall-mounting cabinet, L=600 H=1100 P=400 mm

    HS81-HS/10R: Base Rack and up to 10 card racks, self-standing cabinet, L=800 H=2100 P=800 mm
    About 20 different cards can be used, each dedicated to different functions such as flame suppression, gas detection, intruder alarm, smoke detection and communication with other systems and/or panels. Hot swap of cards and power supplies, with no need for panel shutoff.
    The HS81-HS panel has a dedicated rack for the operator’s interface and consists of a large alphanumeric display, a keyboard and LED indications to show the system status. Each panel HS81- HS has its own AC feeder and battery charger, which allows the panel to work even without an external power supply.

  • Oil and Gas Production

    We offer a complete range of comprehensive services for the oil and gas industry. Our expertise and industry experience enable us to provide a full scope of solutions for small as well as large facilities and to provide our customers with tailor-made products and services to protect life, profitability, and the environment. Our considerable resources and qualified personnel allow us to keenly focus on customer care, as well as on consistently high-quality products and services.


    Safety is not an option in the refining industry – it’s a prerequisite that’s essential to life, to the environment, and even to smart financial investments. And when it comes to industrial safety services and products for the refining industry, Honeywell Industrial Fire Protection is the solution-provider of choice.


    The petrochemicals industry has always been vulnerable to fire safety issues, but today more than ever, plant security plays an increasingly large role in safety considerations. Our solutions meet the wide range of cost, regulatory, technical, and insurance needs in today’s petrochemicals industry.

    Power Generation and Distribution

    Power generation and distribution is as important as it is challenging, which is why special solutions are required to mitigate potential risks and to help you adapt to the changing landscape of electricity generation. Furthermore, our solutions improve plant uptime, reduce total cost of ownership, and ensure regulatory compliance. Honeywell Industrial Fire Protection provides integrated safety and information solutions for complete plant-wide safety and control – for conventional as well as renewable energy generation and distribution.


    Mining is a particularly difficult industry when it comes to fire detection and voice alarms. The dusty, wet, and potentially explosive environment presents unique fire and smoke detection challenges; plus, installation and maintenance of detection and voice alarm systems is more demanding due to difficult access, especially in underground tunnels. Traditional smoke and fire detection systems have always struggled to perform in the difficult and hazardous environments in the mining industry: concerns like poor detection, shorter detector life, false alarms, and high levels of maintenance all influence the ongoing costs of mining operations. We overcome these challenges by providing reliable early warning fire detection and voice alarm systems to enable rapid responses – even while operating with low maintenance – in order to reduce costs and safeguard your profitability.

    Pulp and Paper

    Pulp, paper, and paperboard mills are located all around the world and employ hundreds of thousands of people. The pulp and paper industry is susceptible to equally severe problems with fire and dust explosions due to the nature of the industry. Dangerous sparks and hot particles can be generated in the production processes and be the cause of fire, thus leading to loss of revenue and/or human life as well as major damage to production lines and machinery.


    Production plant fire risk is a factor that must be addressed in order to ensure that seamless business operations and profitability are protected at all times. However, the range of possible manufacturing hazards is just as multifaceted as the industry itself, so custom-made solutions are necessary to address the specific issues in every individual manufacturing facility.

    Pharmaceutical & Biotech

    Numerous and dynamic factors increase the challenges of fire protection and controlled emergency evacuations in the pharmaceutical and biotech industry. Taking into account the often specific building structure and building requirements for pharmaceutical and biotech industry as well as that a fire could release substances that may be harmful to workers, fire-fighters or other people involved, many challenges must be overcome to find the right fire detection system for such a facility.
