The Honeywell Scame HS81 (H-S81-HS) is a modular industrial fire and gas control system that combines fire detection, gas detection and suppression control in one panel, with redundant CPUs, redundant power supplies and hot-swappable I/O cards. It is available as a compact controller with up to 8 I/O cards and as a self-standing panel with up to 130 I/O cards. Akan Industrial and Automation engineers, supplies and commissions HS81 systems in Türkiye as a solution partner of Scame Sistemi.
What is the HS81 system?
Scame Sistemi, based in Arluno, Italy, has developed industrial fire and gas detection systems since 1979 and became part of Honeywell in 2015. The HS81 is its industrial fire and gas platform for high-risk sites such as oil and gas facilities, power plants, ports, airports and chemical plants.
Compact Industrial Fire Controller
The compact controller (H-S81-HS/C-ULS single supply, H-S81-HS/C-ULD dual supply) integrates flame, gas and smoke detection, logic control and networking, suppression and extinguishing, public address, sounders and beacons. It consists of an enclosure, display, redundant CPU and up to eight I/O cards chosen to suit the facility.
| Parameter | Value |
|---|---|
| I/O cards | Up to 8, addressable |
| Suppression zones | 1 per I/O card |
| Points per zone | 99 inputs, 99 outputs, 99 associations |
| Programmable zones | 300 fire and intrusion zones |
| Redundancy | CPU and power supply |
| Hot swap | All I/O cards, CPUs and display |
| Networking | TCP/IP between panels |
| Third-party interface | Modbus RTU, Modbus TCP |
| Remote I/O | F7011 safety bus, up to 64 modules per control card |
HS-81 self-standing panel (S81-HS/1-10R)
For medium and large applications, up to eleven 19”, 3U anodized aluminium racks are installed in a steel cabinet with swing frame and acrylic glass door. The first rack contains the base system (one or two CPUs, operator display and keyboard); each additional rack has a rack controller and 13 I/O card slots. Cards connect to field wiring via prewired connectors and terminal blocks.
| Parameter | Value |
|---|---|
| Functions | Addressable and conventional fire detection, gas detection, suppression |
| Max. I/O cards | 130 |
| Redundancy | CPU and I/O card |
| Networking | TCP/IP |
| Certification | SIL 2 |
| Max. battery capacity | 120 Ah |
| Wide-area I/O | F7011 safety bus |
CPU card
The CPU card processes all information from the other cards. Two CPUs can run in parallel; if the primary fails, the secondary takes over immediately without interrupting operation or losing events.
