Description
The Det-Tronics Model 8000 (Part: 226650-001) is a robust, microprocessor-based control system designed for industrial gas detection and fire monitoring. It serves as a central hub for up to 8 independent sensor channels, providing continuous monitoring for combustible and toxic gases. This controller is widely utilized in high-risk environments such as offshore drilling platforms, refineries, and chemical processing plants, where it processes field signals to activate local alarms, ventilation systems, or automated emergency shutdown (ESD) sequences.

🚀 Recommended Series Models & Integration
The Model 8000 integrates seamlessly with Det-Tronics detection hardware to form a complete safety-instrumented system:
- CGS / PIR9400 – Standard catalytic and infrared gas sensors
- U5015 – Explosion-proof flame detector (common in connected systems)
- PointWatch Eclipse – Infrared gas detector for combustible gases
- FlexVu UD10 – Universal display unit for field sensor management
- Relay Output Modules – For expanding the number of controlled alarms/beacons
- Power Supply Unit (PSU) – Required for stable 24VDC rail power in high-load scenarios
- Serial Interface Module – For communication with a host PLC or DCS (Modbus)
- Calibration Kit – Essential for field maintenance of sensors (226650-001 specific maintenance)
⚠️ Integration & Maintenance Note
The 226650-001 is designed to handle multiple sensor technologies. When configuring the 8 channels, ensure that the DIP switches and jumpers on the input cards are set to match the specific sensor type (e.g., 4-20mA vs. bridge) for each channel. Incorrect settings will result in “Fault” or “Sensor Open” alarms on the display.
