Frequently Asked Questions

• Q: Is this detector hot-swappable?

  A: No. The unit must be electrically isolated from the supply power and the BMS interface before removal or installation.

• Q: Does the device support multiple fuel types?

  A: Yes, it is field-calibratable to recognize the spectral signatures of natural gas, oil, and coal flames.

• Q: What is the maximum signal latency?

  A: The hardware architecture ensures a signal latency of less than 3 seconds for flame-out detection.

• Q: Can this unit provide real-time flame intensity data?

  A: Yes, the 4-20 mA analog output provides continuous flame intensity monitoring to the connected DCS or burner controller.

• Q: Is the device compatible with Ethernet diagnostics?

  A: The unit supports integration with Ethernet router-based diagnostic systems for system-level monitoring.

• Q: Does the relay configuration support fault reporting?

  A: Yes, the dual SPDT relay contacts can be configured to represent both flame status and internal device health/fault conditions.

• Q: How is the device powered?

  A: It requires a nominal 24 V DC power supply with a power consumption profile between 4 W and 8 W.

• Q: Does the device require specific optical orientation?

  A: Yes, the unit must be oriented to focus on the combustion zone, ensuring that background radiation is filtered out while the flame flicker frequency is captured.
