GST-200 Series System Architecture
The GST-200 Series can be structured in a star or loop topology depending on building requirements. A single panel connects to:
- Addressable Detectors (smoke/heat)
- Manual Call Points
- Sounders and Flashers
- Input/Output Modules
- Repeater Panels
- Network Panels
All devices communicate digitally with the control panel via two-wire loops, reducing cabling costs while maintaining high reliability.
How the GST-200 Works
The working principle of the GST-200 series is based on continuous communication and intelligent decision-making:
- Detection: Each detector continuously monitors its environment for smoke, heat, or gas.
- Communication: The detector sends status data to the control panel at regular intervals.
- Decision: The control panel analyzes the data using built-in algorithms to identify genuine alarms, minimizing false activations.
- Response: Upon detecting a confirmed fire signal, the panel triggers programmed outputs such as activating alarms, relays and emergency systems.
- Logging: All activities are recorded in memory for audit and maintenance.
