Selection Recommendations
Choose IS200FOSAG1AAA when your flame detectors or optical sensors require the “AAA” firmware variant or enhanced discrimination features. Select over IS200FOSAG1A when compatibility with specific sensor models or advanced flame quality monitoring is required. Verify “AAA” firmware matches your sensors before commissioning. For standard flame detection applications, IS200FOSAG1A may be sufficient.
Precautions and Important Notes
Use ESD-safe handling. Verify sensor wiring and optical alignment. Confirm “AAA” firmware supports your specific flame detectors and sensors. Never interrupt firmware updates. Board draws 2.0A – verify rack power capacity. Document all configurations. Store spares in anti-static packaging. Do not mix IS200FOSAG1AAA with IS200FOSAG1A in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all flame detection functions during commissioning. If replacing an IS200FOSAG1A with an IS200FOSAG1AAA, verify all sensors are compatible with the new firmware before installation. The IS200FOSAG1AAA is critical for flame protection – ensure all detection and protection functions are verified before placing in service. Regular sensor cleaning and alignment should be performed per manufacturer recommendations.
