Reliable flame detection and burner-to-burner discrimination in multi-burner boilers is significantly more challenging with the NFPA 85 requirement to prove “flame not detected” prior to burner start-up. This NFPA requirement along with difficult discrimination challenges, such as low NOx burners and opposed fired boilers, are demanding more powerful signal analysis and tuning capability from flame detection systems. The IDD 9000 employs a Digital Signal Processor (DSP) based flame signal processing method to offer advanced tuning capabilities necessary for a NFPA compliant system.

The IDD 9000 Flame Amplifier is designed for easy upgrade of existing Forney flame amplifiers with most installations simply requiring a flame amplifier replacement and reconnection of existing wires to improve flame detection and discrimination. The IDD 9000 is available in panel or rack mount; single or dual channel configurations. The dual channel configurations use two fully independent channels to support two flame detectors simultaneously.

✔︎ Enhanced Discrimination and Tuning – Increased IDD frequency response options along with spectrum weighting capability for tuning to unique flame patterns.

✔︎ Storage for eight operating profiles allows BMS controlled or manual file switching for instantaneous recall of optimized performance for a variety of fuels and burner operating conditions.

✔︎ Flame signal processing can be IR only or UV only on each channel.

✔︎ Connecting an IDD and UV-4 flame detector to one dual channel IDD 9000 amplifier allows supervision of a burner/ igniter pair.
