Kidde Aerospace 30-215-8 Flame Detector

The Kidde Aerospace 30‑215‑8 is a dual‑sensor flame detector that uses ultraviolet (UV) and infrared (IR) optics to detect both visible and invisible flames in aircraft fire protection systems. Common failure modes for this model include optical sensor contamination or degradation, power supply voltage dropout, and internal circuit board shorts caused by moisture ingress or thermal cycling. First‑check diagnostics: verify the 24 V DC input is within spec and stable; inspect the UV/IR sensor housings for dust, corrosion, or physical damage; and test the detector’s output logic with a multimeter to confirm proper high/low signaling per the aircraft wiring schematic.[oss-gpt-20b] Post Comment
