HS-81 CONTROLLER – Comprehensive F&G Safety for Operational Continuity

Honeywell is the world’s largest provider of advanced automation solutions for the process industry. The HS-81, a complete industrial-grade fire and gas system, contains flame, gas, and smoke detection; logic control and networking equipment; suppression and extinguishing capacity; public speech, sounders, beacons, and other safety components. These components, which can be used to monitor the level of plant safety, provide rapid and coordinated emergency response capabilities. The system’s extremely stable architecture and innovative software enable faster and more accurate judgments, resulting in maximum plant uptime. The HS-81 can meet even the strictest requirements for functional dependability and availability because it is very resistant to electromagnetic disturbances and can keep working even in bad weather.
